Engine size, horsepower and the type of fuel used often dictate the grade of oil required for periodic changes. However, it's not that simple. There are many oils, there are several quality standards, and even if you have a specific car model in mind, it is sometimes quite difficult to understand the variety of lubricants. Today we will figure out which oil is best to pour into the 16-valve Lada Priora engine, and which one is better to refuse.

Does each engine have its own oil?

If the engine oil is not selected correctly, it will begin to be squeezed out through the breathers

By and large, all modern VAZ cars that come off the assembly line today are equipped with the same type of engine, if not a modification of one base engine. In the case of the Priora, the plant at different times installed and is installing several engines on this model:

• old 8-valve 1.6-liter 87-horsepower VAZ 21116 engine;
• 16-valve 98-horsepower 1.6-liter VAZ 21126 engine;
• forced 106-horsepower 16-valve 1600 cc engine VAZ 21127;
• 1.8-liter 98-horsepower 16-valve engine 21128.

If you don’t take into account the eight-valve engine, then all the others are absolutely identical in design and in the volume of oil poured - it’s a stable 3.5 liters. Even in terms of technical characteristics, the engines differ very slightly, so there is no need to talk about a radical difference in lubrication. The manufacturer agrees with us.

What kind of oil to pour into Priora, what does AvtoVAZ say?

By and large, it does not matter what kind of oil is poured into the Priora engine from the factory.

Simply because it changes immediately after running in, which is about two thousand kilometers. Many people change the oil right away. Some oil manufacturers, for example, Lukoil, claim that in every new Priora, their 10w-30 mineral running oil splashes in the crankcase, TNK claims that their semi-synthetics are poured into Prioras, and a list of brands and types of oils recommended by the plant is given in the manual operation. On four pages.

In short, the plant is responsible only for the break-in period and does not particularly advertise the brand and manufacturer of the break-in oil, and this is not necessary. Now we’ll figure out for ourselves which oil to pour into the 16-valve Priora and what parameters to choose.

Oil selection parameters for Priora

Standard Priora owner kit: MANN oil filter and Motul synthetic oil

The conversation about choosing the optimal oil for a 16-valve Priora can drag on ad infinitum, so we will outline a number of basic parameters that should be taken into account when choosing a lubricant when replacing:

1. Mineral oils . Let's make a reservation that the manufacturer does not matter in our case. Mineralka is an inexpensive oil intended for use in derated low-speed engines. The product is made by distilling oil, so the percentage of additives in it is minimal. This indicates low cleaning properties and a short service life before replacement. Nevertheless, you shouldn’t think that mineral water is completely worthless. It needs to be changed more often and the motor should be operated in indoor ficus mode, without unnecessary loads and overheating.
2. Synthetics. Synthetic oil is the purest chemical and, like any substitute for natural components, is much more expensive than mineral water. And this is not in vain, since during the manufacturing process of synthetics it is possible to add any additives and radically change the properties of the lubricant, you can literally get a universal lubricant. It will work well and for a long time in both low-power and high-power engines. It lasts longer than mineral water, lubricates better, does not thicken much in winter, and does not lose viscosity much in summer.
3. Semi-synthetic oils . Perhaps the most popular oil among Prior owners - it has balanced lubricating properties, a reasonable price and a huge range.

There are several other types of motor oils, but they have nothing to do with Priora. At least for the base car.

In addition to classifying oils by composition, they are divided into viscosity classes at a certain temperature according to the SAE standard; this classification is shown in the table below:

Classification of motor oils

This table suggests that the choice of oil now depends on the operating conditions of our car.

In addition to air temperature, it is also worth considering the year of manufacture of the car, since engine oil standards changed in 2003. For example, for Priora manufactured before 2004, it is recommended to use oil marked SL/SM, after - with markings S.M.. This only applies to synthetics.

Shell, Castrol, Total or Lukoil?

The principle of reasonable sufficiency is what you need to use when choosing oils for your Lada Priora.

We are aware that the loads in the Priora engine differ from the operating mode in the six-liter 500-horsepower 12-cylinder naturally aspirated engine from AMG, which is why there is no point in overpaying for the brand. Domestic oils from trusted manufacturers cope quite well with lubricating the Priora engine, the main thing is to change the oil and filter on time.

A non-representative survey of Prior owners in 2016 showed that about 21% of respondents prefer Shell oil, about 18% trust the German quality of Mobile1, and the rest equally prefer Lukoil, Rosneft and XADO.

Oil selection survey

conclusions

Thus, if you follow the rule of changing engine oil not every 15 thousand , as the manufacturer says, and 10,000 km, add no more than 150 g per thousand mileage (this is exactly the oil consumption of a Priora with a healthy engine), then there should be no problems with the engine. High-quality lubrication and smooth roads for everyone!

The Lada Priora engine, like other cars, needs regular lubrication. Motor oil helps the engine operate efficiently for a much longer period of time and reduces wear on its components.

Choosing engine oil for the Lada Priora, as some experts say, is a rather complicated procedure.

In order to determine the quality of the oil, you also need to know about the required quantity (volume) of lubricant for Lada Priora.

According to the instruction manual and factory recommendations, it needs from 3.2 to 3.4 liters of fluid - this is the average value. In order to determine exactly how much oil goes into the engine, you should fill in 3.2 liters of fluid, warm up the engine for several minutes, after which, by measuring the lubricant level, you can determine the missing amount.

The amount of oil is measured using a dipstick, which has two marks - maximum and minimum. Between them there should be an indication of the lubricant level. It is clear that if the oil is below the minimum, then it should be added, but in no case should you pour lubricant so that it exceeds the maximum mark. This will increase the pressure inside the lubrication system and can lead to the destruction of some engine components, as well as squeezing out oil.

To make it convenient to change the oil, it is worth buying containers with a volume of about 4 liters.

The best oil for Priora

There are several types of oils, depending on its base - synthetic and semi-synthetic, as well as mineral, which are now practically not used. For a 16-valve engine, it is suggested to use synthetic brands.

To select an oil, you should decide on the brand and select the required viscosity index that corresponds to the conditions of use of the car.

For winter, oils marked 0W-5W are best suited - even at temperatures down to minus 35 degrees, such oils will work properly. Thicker oils are also suitable for the summer period.

Manufacturers

There are a huge number of oil manufacturers on the market who offer their products for different types of cars. Typically, global brands produce lubricants of fairly high quality, and their prices are appropriate.

In addition to Western synthetic oils, it is recommended to use domestic ones - for Priora, one of the best choices would be Lukoil products. Castrol and Shell brand products also perform well. These manufacturers have good product characteristics, and they are usually intended for high-power engines. Among well-known brands, Esso and Mobil oils, or others, are definitely suitable.

Oil consumption

Priora has a fairly high lubricant consumption and for every thousand kilometers you will have to count about one liter of fluid. To say that Priora consumes oil is the most accurate opinion about the consumption of lubricant by this car. Thus, every 3000 kilometers it will be necessary to completely change the oil in the system. It is worth noting that under constant loads and accelerations, when the gas pedal works quite intensively, you will need to change the oil much more often.

During the first few days of using a vehicle, the engine uses a lot more lubricant as engine parts grind in. Therefore, the first oil fill and the second can occur with a shorter period of time and mileage between them.

The Priora's consumption also increases if the car has an oil leak into the fuel system - thus the oil burns out very quickly, which can be determined by the type of exhaust gases. If the valve seals are faulty, they will need to be replaced. In addition, a decrease in oil level can lead to other breakdowns.

Change of oil

Even a novice can fill the car with oil on his own, but it is unlikely to be able to guarantee a sufficiently high quality of the car’s operation if the driver does not have sufficient knowledge to fill in new oil.

• To fill, you need to open the neck, check the drain plug, and also replace the filter. The filter element in Priora changes along with the oil.
• Before changing the oil, you first need to drain the old oil; to do this, unscrew the drain plug on the oil pan (after the car has warmed up). The oil flows out for a few minutes, after which you can close the drain and begin pouring fresh lubricant.

It is better to pour into the engine the same type of oil that was used before the replacement - a sudden change from one type to another can lead to engine seizure.

For a beginner, it is best to contact a car service or service station, as this guarantees a high quality oil change, as well as an adequate level of lubrication in the engine system. In addition, car service workers can find some faults and immediately fix them during the replacement process.

Today you can buy it at any auto store, but you need to have a basic understanding of what this substance is and how to choose it. The first thoughts that the engine would need a lubricant appeared in the mid-19th century, when Lenoir was trying to create the first internal combustion engine, and at the same time the pistons were constantly jamming in the cylinders.

Why do you need oil and what are its components?

Automotive lubricant

Engine oil is needed to reduce the coefficient of friction between two metal surfaces. In addition, it helps remove wear products and particles of unburned gasoline from friction pairs, and is involved in cooling parts and protecting them from corrosion.

Modern oils consist of basic components (mineral ones are obtained during the distillation of oil, and synthetic ones - during chemical synthesis in specialized factories), which affect the temperature and viscosity properties, and a package of additives, with the help of which special qualities of oils are created.

For example, a standard oil contains about eight parts of base components, one part of viscosity modifiers and one part of additives.

Additives may include a dispersant (allows the additives not to precipitate), detergent (detergent), antioxidant, anti-wear substances, etc. Therefore, engine lubricant is a complex substance, the composition of which is selected and tested sometimes for 3 years or more.

Common Misconceptions About Motor Oil

• If Priora's oil has darkened, it needs to be changed ahead of schedule. This is not always required, because it darkens due to the fact that the detergent components dissolve products from incomplete combustion of gasoline. Thus, lubricant helps keep engine components clean.
• The replacement period can be determined by eye. This is an incorrect statement, since replacement must be done in strict accordance with the manufacturer's recommendations.
• The oil can be changed irregularly. In fact, if one replacement is missed, deposits in the engine increase in intensity, which leads to slower circulation and potential breakdown of the car's engine.
• You should only choose expensive products. This is incorrect, because if the manufacturer’s recommendations are not followed, even expensive samples can cause harm during operation.
• All-season oil is of worse quality than seasonal oil. What oil is better to fill? Answer: you can easily use an all-season one, because it is developed for difficult operating conditions and tested on all-weather stands (from the African desert to the snows of Yakutia).

Lubricant characteristics are important

• There is no difference between mineral oils and “synthetics”. In fact, it exists and lies in the fact that mineral oils lose their performance characteristics faster, oxidize more intensely, and leave residues on the engine, so for cars with a long time interval between services, it is worth choosing synthetic options.
• The statement that mixing synthetic and mineral options will not harm is also incorrect. This can only be done in extreme cases, when it is not possible to add oil of the same brand on the highway. In this case, as soon as possible, you need to completely replace the oil fluid with a single sample.
• Fuel and lubricants cannot be checked at home. Of course, a detailed analysis will not work, but if, when placing a drop of oil on a newspaper (picked up with a dipstick), it forms a stable drop, then changing the oil in the engine is simply necessary.
• Engine oil must be supplemented with suitable auxiliary additives. This is not necessary, because the manufacturer selects a balanced composition in which additional elements will only interfere.
• Oil can be poured into the Priora only after flushing. This, again, is not true. High-quality modern fuels and lubricants have good dispersing and washing abilities, so the engine does not always need to be flushed. It's better to just shorten the replacement interval.

What kind of oil should I put in the Priora engine?

Motor oils differ for gasoline, diesel and turbocharged engines and in the temperature range of possible use.

The oil for Priora must be selected based on the specific model of this car. For example, on a Priora 1.6i liter with engine 21116 (installed since 2011), it is worth taking the recommended samples with the following characteristics:

For some regions, the 0W sample may also be suitable, which allows you to operate the machine at minus 30-35°C. In addition, there are oils intended only for summer use, as well as energy-saving class samples with low viscosity and an additional additive package (intended for the corresponding engines).

Motor Priora

The Priora can have a 126 engine (cylinder diameter 8.2 cm, produced since 2007), a 127 engine (cylinder diameter 8.2 cm, produced since 2013) or a 128 engine (cylinder diameter 8.25 cm, produced since 2003) ).

They are suitable for oil with the same characteristics as for the 21116 engine. The year of manufacture of the engine affects the oil used, in accordance with API recommendations. For example, on a 128 engine it is advisable to install fuel and lubricants marked SL/SM, and for other variants - marked SM, which means that the oil is designed for engines manufactured after 2004.

Therefore, before deciding which oil to fill, you need to carefully read the specifications for your own car. You also need to take into account the mileage it has. It is believed that the more the engine has worked, the larger the number in front of the letter W should be (indicates the winter period of operation).

The manufacturer recommends filling the Priora with new oil after a mileage of 15,000 kilometers. In dusty areas this figure drops to 10,000 kilometers. The oil filter is usually changed along with fuel and lubricants, which helps to avoid dirt particles getting into the new lubricant. To do this, we take new oil and filter, a rag, a brush with metal teeth, a wrench set to “17”, a container for drained oil (under no circumstances should it be drained on the ground!), and a wrench for turning out the filter.

Changing the oil and oil filter

Draining old grease

1. Sequence of work:
2. Warming up.
3. We put the car on the lift.
4. Open the hood and remove the oil filler plug.
5. Clean the oil drain plug on the crankcase using a brush and a rag.
6. Loosen the tightening on the plug.
7. Place a container for oil (you can make a funnel from a bottle).
8. We turn out the plug and drain the oil.
9. Use a special wrench to unscrew the filter.
10. Now you can fill the filter 2/3 full of oil so that during the first start-up the valve drive parts experience a minimum of “oil starvation”.
11. Lubricate the O-ring with oil (can be treated by the manufacturer himself, for example, with talcum powder).
12. Screw the filter back 0.75 turns until the cylinder block flange and ring touch.
13. We unscrew the plug on the oil filler neck and fill it with fuel and lubricants (it can be filled using a funnel made from a bottle).
14. Using a dipstick, check the level (it should be halfway between the minimum and maximum values), and tighten the plug.
15. We start the engine at idle speed and let it run for a couple of minutes. We check whether oil is leaking from the filter and from under the drain plug.
16. We stop the engine, check the oil level, add if necessary, tighten the filter and the drain plug.
17. We put the mudguard back.

How much oil should be poured into the Priora engine? Documentation from the manufacturer reports that the engine requires 3.5 liters, and about 3.2 liters need to be added. Compared, for example, with the Niva, Priora is a very economical car in terms of consumption of this type of fuel and lubricants, since it “eats” fifty grams of oil per 1000 km (Niva - up to one liter in off-road conditions).

A car engine needs high-quality lubrication. If you do not change the lubricant in time and do not monitor the oil level in the power unit, this can lead to a reduction in engine life. Let's figure out what kind of oil to pour into the Priora. Indeed, despite the fact that there are recommendations from the manufacturer, today a large number of brands of automobile oils are suitable for an engine installed on 2170. Therefore, the choice is very often difficult.

Some general information

The sedan was launched in 2007. Back then, the Priora’s configurations were not so rich, and the first models were equipped with 8-valve internal combustion engines from 2114. This somewhat confused motorists, because the engine was not famous for its service life and reliability. Therefore, after some time, a 16-valve power unit replaced it, and even later its modification appeared. The engine had an increased service life, consumed less fuel and was generally more reliable. But at the same time, requirements for lubricants increased.

Nevertheless, the 16-valve Priora was most loved among motorists. The power of the 1.6-liter power unit was 87 liters. s., and the latest modification has become even more powerful. But the load on the internal combustion engine has increased somewhat. For example, in the maximum version it is equipped with air conditioning, which causes the engine to sags, but this is typical for most engines of budget cars.

What you need to know about modern oils

Now the choice of lubricant for the engine is practically unlimited. There are a lot of manufacturers, and all oils at first glance are similar to each other. However, they are divided into three large groups:

• mineral - obtained by distilling oil. They have relatively low cleaning abilities and a short resource. A clear advantage is low cost;
• synthetic oils are pure chemistry. This lubricant contains a huge amount of detergents and this allows you to extend the replacement interval. Behaves stably both in heat and at sub-zero temperatures;
• semi-synthetic - a mineral base with the addition of additives is used. According to the majority, this is the best option for the 16-valve Priora. It has an average price tag and is great for domestic engines.

Many motorists prefer semi-synthetics. This oil is affordable and still provides good engine lubrication. Overall a great option.

To understand what kind of oil to pour into the Priora, just read the operating instructions. It contains all the necessary information on the oils to be filled. Many people are interested in what is filled from the factory. But in reality this is not so important, because immediately after break-in this lubricant is changed. Many claim that Lukoil 10w30 break-in oil was poured from the assembly line, but whether this is actually true is unknown.

If we do not consider the 8-valve power unit, which is not particularly popular, then the same oil can be poured into all other engines. This is due to the fact that, in fact, this is the same motor, which has been modified several times. The amount of oil to be filled is 3.5 liters. The operating instructions indicate such lubricants as Rosneft-Premium, TNK-Magnum. All these are domestic products of fairly high quality.

But which is better?

It is necessary to understand that there are options for summer, winter and all-season use. The latter are the most popular due to their versatility. They work great both in the cold season and at high temperatures. But even here there are clear recommendations from the manufacturer and they look like this:

• 15w40 - from -15 to +40;
• 10w40 - from -25 to +40;
• 5w40 - from -30 to +40;
• 10w30 - from -30 to +25.

This suggests that the choice should be based on the ambient temperature. For example, if the car is operated in the Far North, then the optimal oil will be one that thickens as late as possible. Those from the above list are 5w40 and 5w30. But if frosts drop below -30, then you need to pour 0w40. The situation is exactly the same with viscosity at high temperatures. In order to worry about this as little as possible, all-season lubricant is poured into the 16-valve Priora.

About specific oils

"Lada Priora 2" is a restyled model of 2013. Most of the changes affected the interior of the car. In addition, as noted above, a 16-valve power unit is already installed here. Semi-synthetic oils are best suited for this engine. An excellent and inexpensive option is lubricants of the SL and SJ categories according to the API classification. In this case, the viscosity is selected based on the region of operation.

"Rosneft-Premium" is an excellent domestic product that is available on the shelves of all auto stores. Many motorists speak positively about this lubricant. The motor on Rosneft runs quieter and smoother. They also highlight MANNOL Extreme, which is excellent for heavy duty use. If most of the driving is in the city, then Mannol will be very useful. Another suitable option is "SINTOIL-Ultra". Inexpensive motor oil with a fairly rich chemical composition. There is also molybdenum, which reduces the coefficient of friction, as well as a package of detergent additives. All that remains is to choose which oil to pour into the Priora from the above.

How to change oil?

The 2nd generation Lada Priora engine contains about 3.5 liters of lubricant. Therefore, it is worth buying a 4-liter canister. The remainder is usually enough to top up until the next change. The process itself is quite simple. The car is installed on a horizontal surface; if desired, the front part can be raised by 10-15 degrees for a more complete drainage of waste.

The power unit must be warmed up to operating temperature. After this, the drain plug is unscrewed and the engine oil is poured into a prepared container. The old filter is unscrewed and a new one is installed in its place. lubricated with oil. Next, tighten the plug and fill in fresh oil. We check the level using the dipstick. That's it, we have completed the oil change. "Priora" is ready for further operation.

Important nuances

Do not forget that an engine with high mileage often requires the use of thicker lubricants. This is due to natural production. The fact is that oils that are too thin will flow through the gaps in the cylinder-piston group that appear during operation. At the same time, a lubricant with a viscosity of 5w30 is considered optimal for a new engine, and 10w40 for a used one. In any case, there is no need to go beyond the viscosity recommended by the manufacturer.

Another important detail is waste consumption. Some oils burn more, others less. But a lot depends on the mode of operation. The more often the engine spins up to high speeds, the more oil will burn. In this case, the lubricant is selected individually, by trial and error.

Compliance with replacement intervals

Regardless of what kind of oil is poured into the Lada Priora, it must be changed regularly. The first replacement after running-in is carried out after 2-3 thousand kilometers. The same rule applies to those engines that have undergone major repairs. Failure to comply with these requirements may result in improper operation of the power unit.

Further, the manufacturer recommends replacing it once a year or every 15 thousand kilometers, whichever comes first. Therefore, if you have driven only a few thousand in a year, this does not mean that you don’t have to change the oil. During this time, it loses some of its performance properties and will no longer work as expected. Many motorists change the lubricant in the power unit every 10 thousand. This is partly the right decision. Most oils acquire a dark color over this mileage, which indicates high cleaning properties. Therefore, no matter what kind of oil is poured into the Priora, it must be changed regularly.

About the gearbox

It is installed on the Priora. Its service life directly depends on operating modes and on the regularity of changing transmission oil. As for the manufacturer's recommendations, a complete replacement must be performed every 75 thousand kilometers or after 5 years, whichever comes first. In essence, everything is exactly the same as with the engine, only maintenance is performed much less frequently.

The box was filled with TM 412 from the Lukoil company from the factory. This is a break-in transmission oil, which is replaced during the first maintenance. During break-in, gear shifting will be performed with greater effort. This is due to the characteristics of the transmission oil. It is necessary to clean the system of technical debris.

Ideal for checkpoints

Motorists are interested in which oil is most suitable for the Priora gearbox. It is worth noting right away that there is no need to skimp on the quality of the lubricant. Replacement is already done quite rarely, so once every few years you can spend money. It is quite possible that by doing this you will significantly extend the life of the car’s manual transmission. As for viscosity, according to manufacturers’ recommendations it should be in the range from 75w80 to 80w90. Again, a lot depends on the region where the car is operated.

It is worth paying attention to the fact that the oil volume in the Priora (manual transmission) is exactly the same as in the engine. Usually 3.5 liters is enough for a complete replacement. Actually, the process is performed in a similar way. The MPKK has the same drain plug, and there is a dipstick in the engine compartment. It is advisable not to overfill the transmission, so after we fill it with about 3.5 liters, we take a short break. This is necessary so that all the lubricant flows into the pan. Check the dipstick and top up if necessary.

Let's sum it up

"Lada Priora" (126 engine) is a modern, comfortable sedan from a domestic manufacturer. The engine resource before major repairs is quite long. But the internal combustion engine does not always run as long as stated in the passport. This is partly due to the fact that the deadlines for replacing lubricants are not met. Or drivers save money and pour mineral water, and also change it every 10-15 thousand kilometers. This negatively affects the operation of the power unit.

There is also a risk of stumbling upon a fake, which also does not bode well for the engine. Therefore, it is recommended to purchase oils for internal combustion engines and manual transmissions only from a dealer or in trusted places. At least this way you can be sure of the originality of the product. So we figured out how much, when and what kind of oil to fill. Don’t forget about replacing the filter, because if you leave it, the whole procedure is reduced to zero. Do you like to drive? Then change the oil a little more often.

Many Russian motorists complain that the engines of domestic cars consume a lot of lubricant. Today, Russian-made cars manufactured at AvtoVAZ are equipped with 16-valve engines of modifications 21126, 21127 and 21128. The designers of these power units officially claim that the first two 1.6-liter models should consume no more than 50 grams of lubricant per 1 thousand kilometers. . But the oil consumption of the Priora, equipped with the domestic engine 21128, is expected to be 6 times more, that is, up to 300 grams for the same distance. What is the reason for such great gluttony? Does this indicator depend on what kind of engine oil is used for the Priora?

Features of the motor brand 21128

This power unit is installed not only in Priora. They are also supplied to other brands of VAZ cars. Wanting to reduce the cost of production, the authors of the modernization of the 21127 engine decided to leave the cylinder-piston block unchanged. The solution was simple - increase the volume by increasing the piston stroke. To implement it, the connecting rod and crank mechanism was changed. Shortened connecting rods allow the pistons to increase their stroke.

Despite the manufacturer’s assurances that the engine’s service life is 200 thousand km, in practice it turned out to be much less. This is explained by the fact that the parts of the cylinder-piston block began to experience much greater loads. The engine itself is a 4-cylinder, injection. The timing camshafts are located at the top, the gas distribution mechanism drive is a belt drive. But if it breaks, the valve cylinders do not bend. But wear of the rings and cylinder walls progresses quite quickly. As a result, the engine becomes so “hungry” that it consumes oil for the Priora from 0.7 to 3 liters per 1 thousand km. Thus, without major repairs, it cannot travel even one hundred thousand kilometers.

Other reasons for excess grease consumption

In addition to the above-mentioned shortcomings due to the fault of the manufacturer, there are a number of other reasons why synthetics or semi-synthetics poured into the engine are overused. This applies to all engine models, regardless of manufacturer.

If a lot of oil fluid is burned, you can see bluish exhaust gas coming from the exhaust pipe. Over time, an oily black film can be found on its edges. But it is impossible to determine the reason why this happens without opening the engine.

Priora is equipped with several engines: 8 and 16-valve with a volume of 1.6 liters, as well as the above-described 1.8-liter with 16 valves. They all have different power - from 81 to 120 horses. In order to choose the right lubricant for them, it must meet certain characteristics. The lubricant must be synthetic or semi-synthetic. So what kind of oil should I use? Lada Priora uses engine oil corresponding to classes SJ, SL - according to the American API specification. Such lubricants are used for gasoline engines starting in 1996. Which oil is better to fill - SJ or SL?

Lubricants of level SL and higher are required to be used in 16-valve engine models. They are designed for both conventional and multi-valve engines, including turbocharged ones. These oil compositions have low volatility and extended drain intervals. Good cleaning qualities allow you to promptly remove carbon deposits, soot, and other harmful deposits from the engine. SL class motor oils can be recommended for all Priora power units.

Another important characteristic is viscosity, defined by the SAE standard. As a rule, all-season motor fluids that have a certain level of low-temperature and high-temperature viscosity are poured. For example, in the 5W30 indicator, the number 5 means that the pumpability of the lubricant, as well as the engine crankability, will allow a cold engine to be started normally at sub-zero temperatures, down to -30°C. The number 30 after the letter W determines the kinematic and dynamic viscosity of the lubricating mixture in a warm, running engine. It is usually measured in laboratory conditions, the oil composition is heated to temperatures of +40°C, as well as +100°C. Although the cylinder-piston group heats up even to +250°C, engine oil also works there, reducing the friction of the piston rings on the cylinder walls.

The higher the level of high-temperature viscosity, the less fluidity the lubricant will have. At the same time, the oil film on the surfaces of parts is stronger and more stable.

For Priora engines, the recommended level is 30 or 40. Synthetic lubricant with viscosity 30 (for example, 5W30) is best used in unworn engines, when the gaps between the surfaces of the parts are still small. Over time, you will have to switch to a thicker, semi-synthetic composition, which has a viscosity characteristics of 40.

Low-temperature ductility is determined by the first digit in the designation. For areas with harsh winter climates, it is recommended to take 0W30 - the engine will start even at a temperature of -35°C. For moderate latitudes, 5W30 or 5W40 is quite suitable. For cars operating in the south of the country, we can recommend 10W40 - the maximum cold start temperature will be -20°C. This lubricating composition does not lose its viscosity in hot climates.

Popular brands and grades of lubricants

As the first fill for Lada Priora engines, a good semi-synthetic composition from the domestic manufacturer - Lukoil is used. The first maintenance with a lubricant change is performed after 2.5–3 thousand km. Further, changing the oil in the Lada Priora engine depends on operating conditions, fuel quality, brand and manufacturer of motor fluid. If you want to save your engine, an oil change on a Priora should be done every 7–8 thousand kilometers. Although, according to the manufacturer, the lubricant requires replacement after 10–15 thousand km.

It is worth paying attention to such famous manufacturers as Esso, Mobil, Shell, ZIC, Total. Their range of synthetic and semi-synthetic oils is quite wide. The only negative is the higher price compared to domestic manufacturers.

It is not necessary to buy an oil mixture that has API SL. Later level compositions, SM and SN, are also compatible with SL. At the same time, their performance qualities are even better.

If the car’s warranty has already expired and there is no need to carry out scheduled maintenance at the dealer, in Lada Priora you can change the engine oil yourself. This process is simple. You just need to adhere to a certain sequence of actions. You must purchase in advance a 4-liter canister of motor fluid with suitable properties, as well as an oil filter. If you are going to switch to a different viscosity or change manufacturer, you will additionally need to flush the engine.

Soft flushes, according to the conditions of their use, are poured 200–300 kilometers before changing the lubricant. During this time, they clean the engine of toxins. Others pour right before you change the oil. Then the engine idles for 5 minutes to half an hour. It all depends on the specific wash. You should prepare: your own set of wrenches, a container for used lubricant, rags.

1. The engine warms up well, the car is placed on a lift or over an inspection hole.
2. The filler neck under the hood is released. The drain plug is carefully unscrewed with a 17 key, and a container for draining is first placed in the bottom of the crankcase.
3. The old oil is completely drained along with the flush. It is advisable to suck out the remaining lubricant from the bottom with a large syringe with a tube - after all, it is very difficult to park the car in an absolutely horizontal position.
4. The old oil filter is unscrewed. A new one is installed, half filled with new grease.
5. The drain plug is screwed in and about 3.5 liters of lubricant flows into the engine through the filler neck. The level is checked with a dipstick; it should be halfway between MIN and MAX.
6. The engine starts and idles. After 5–7 minutes, the oil level is checked again. Top up if necessary.

Your car is ready to travel again until the next consumable replacement.
