Some shipowners choose oil for 2-stroke boat motors, based either on the experience of others or on your own. Both of them are no good. Of course, you need to listen to the advice of experienced friends, but you should act as the manufacturer recommends. A much sadder situation is when the owner of the vessel transfers his experience of handling... a car to the PLM.

Despite constantly rising prices, you need to choose the right oil for two-stroke outboard engines. And for this you need to have a clear idea of ​​what it is like. As you know, all options on the market are divided into two large groups:

• synthetic;
• mineral.

Which representative should you give your preference to? A more expensive branded one or a regular one, but cheaper? Let's try to figure it out.

How is “mineral water” different from “synthetics”?

The main difference between them is the material that is their basis. If mineral oil For two-stroke engines While boat motors are created on the basis, roughly speaking, of oil, synthetic ones are obtained from specially obtained components. The latest are all sorts of:

• alcohols;
• esters;
• olefin polymers.

Experts recommend carefully reading all labels on the packaging. If “Synthetic” is displayed here, then this only indicates the presence of a synthetic base. In addition, such inscriptions are typical for companies that use marketing to attract new customers. Simply put, we are talking about “mineral water” with improved lubricating properties.

The presence of the inscription "Full Synthetic" is an almost 100% guarantee of a synthetic base. True, unscrupulous manufacturers can mix “mineral waters” here, thereby increasing the amount of harmful emissions and reducing the value of the biodegradability indicator.

What to prefer?

So, in all this diversity, the inexperienced boat owner is lost and is not able to understand what kind of oil to pour into the boat engine. And all because such people simply do not carefully read the operating instructions for the unit. As a rule, the manufacturer of the equipment always indicates what needs to be “poured” into the engine.

Very often the recommendations mention the TC-W3 standard. Unless otherwise explained in the documentation, you can use mineral varieties that meet this standard. In addition, the manufacturing company must be more or less well-known and inspire trust. This is ideal.

If you are interested in oil for the gearbox of a boat motor, one of the modern models(as a rule, these are powerful injection devices), then apart from the options listed in the manual, nothing else can be used! Since the PLM was created with “synthetics” in mind, it should only be “fed” with it.

Is it possible to take synthetic-based gear oil and pour it into a regular two-stroke? Yes, it can be done. At the same time, such an act will not harm the power unit at all. Quite the contrary. You should not think that mineral is worse and will not allow the equipment to work out its intended resource 100%. No worse and, of course, it will allow it. It’s just that the cost of purchasing it will be much lower.

Varieties and prices

One of the most famous on the market (both domestic and global) is Yamaha engine oil. As you know, the manufacturer cares very much about its customers, and therefore has developed a special line of lubricants under the Yamalube brand.

For example, 2M Two Stroke Semi-Synthetic for Outboards costing 360-400 rubles per liter will ensure ideal operation of an engine operated in harsh conditions. This grade of oil guarantees protection against corrosion/wear and provides ideal lubricating properties.

Yamalube oil

Another famous brand- Motul. Products offered to the Russian consumer, compatible with any lubrication system: both with separate and mixed. The additives used prevent the formation of scale and reduce coking of spark plugs and the formation of soot. One of the main advantages of the product is the ability to quickly form an emulsion (stable) during the process of combining, that is, mixing, with gasoline. Both unleaded and leaded.

A typical representative is Motul outboard tech 2t. Its cost in Moscow stores is about 700 rubles.

Motul outboard tech 2t oil

Anyone who prefers the Quicksilver brand knows that the oils it offers are suitable for any PLM. However, there are some differences:

• Premium category - can be used for engines with a power of at least 2.5 and no more than 115 horsepower, with the exception of Optimax from Mercury;
• Premium Plus category - with any power units;
• DFI - with devices having a direct injection system.

For example, a liter bottle of Premium TC-W3, made in the USA, will cost about 800 rubles.

Are you interested in oil for Suzuki engines? Then you can purchase Marine Ultimate 2t. TC-W3, manufactured by Nippon Oil. The price of a liter plastic canister is about 520-530 rubles. When using this lubricant, you must strictly follow the proportions indicated in the user manual!

Marine Ultimate oil 2t. TC-W3

As you can see, oil for 2-stroke outboard engines in Russian stores is presented in wide range. Moreover, the cost is quite acceptable, considering the importance of the PLM for the boat and its owner. Of course, products from official manufacturers deserve trust.

Some experts are convinced that very soon oil for four-stroke outboard engines (and only this!) will be in demand by Russian shipowners. But statistics convince us of the opposite: "two-stroke", firstly, are more numerous; secondly, the demand for them is only growing every year.

Which oil is better for two-stroke and 4t outboard engines?

The oil requires a variety of properties depending on the type of outboard motor. Today I will tell you how to understand all the nuances of the choice and what you should vote for with your ruble.

Motor oil for boat engines 2t

This oil works when mixed with gasoline. The product must have good combustion properties and low ash content. It’s good when oil for two-stroke outboard engines burns together with gasoline, leaving no residue. Otherwise, carbon deposits will form on the spark plugs, piston rings, and in the combustion chamber. Plus, the engine will smoke a lot, which is also a minus.

Oil for outboard motors 4t (four-stroke)

For 4-stroke engines, other characteristics are relevant. Such mechanisms literally float in lubricant; maximum friction reduction and excellent holding power on the metal are key. Higher demands are placed on high-speed sports engines.

All declared performance characteristics must last longer than those of 2-stroke engines. I advise you to pay attention to transmission oil for outboard engines from Yamalube, it is ideal for heavy loads.

Which oil for 2t outboard motors is better in terms of additives?

Products in this segment do not have a precise chemical composition. Essentially, it is a mixture of various carbohydrates and additives. Special additives significantly increase performance characteristics.

The most common of them are:

• anti-oxidation, anti-corrosion– protect against chemical corrosion of metal. This is very important for outboard motors, as they operate in conditions of high humidity;
• detergents– wash away solid particles, carbon deposits, clean the surface;
• anti-foam– block the formation of foam. Otherwise, it can provoke dry operation of the mechanism. This is a direct path to jamming and high wear;
• anti-wear, extreme pressure– protects parts subject to friction from wear.

What are dietary supplements

The main ones include additives for rapid decomposition in nature. The point is that in the design of 2 stroke engines part of the gasoline-oil mixture “flies into the pipe.” Because of this, in some European countries The use of such engines is prohibited. Additives protect environment and contribute to the rise in price of the product by 50-80%, which is significant. This is of no benefit to the mechanism itself.

There are additives that correct the viscosity index and reduce the pour point. The higher the viscosity grade, the thicker the lubricant. Optimal solution can be found in the technical specifications of the motor. A less viscous substance burns better and penetrates accurately into parts. More viscous - gives high holding capacity and better protection. Golden mean offers the Quicksilver brand, pay attention to Motul oil for outboard engines.

Important little things

When choosing oil, you should take into account that products from different manufacturers should not be mixed. If the components react, you can provoke a change in properties for the worse. Please note that the finished product cannot be stored for long periods of time. Base oils without additives last longer. In any case, it is better to buy a more “fresh” sample.

Check out the differences between the different types of oils:

• mineral (base) oil into the gearbox of a boat motor - are produced when oil is separated into its components. This The best decision for engines of small, partly middle class, old mechanisms. There is no point in overpaying for synthetics, since most of the properties will not be realized. Look for available options in the Lukoil line;
• semi-synthetic, synthetic– these varieties are obtained by processing polyalphaolefins. The products are noticeably more expensive, but more technologically advanced (Motul). In terms of characteristics, it is noticeably ahead of its mineral comrades. This the best option for engines with injection and oil dosage systems.

• MOTUL– the famous French brand specializes in the development and production of chemicals for Vehicle and industry. Motul oils have no analogues and are suitable for daily use. The physico-chemical properties of the product are maintained throughout long term operation and guarantee ideal engine operating conditions;
• Husqvarna– the Swedish company has earned the status largest manufacturer various garden tools, equipment and related products. The products demonstrate the highest quality and are used for domestic and professional needs;
• LUKOIL– the production of oils is a separate area of ​​activity of the Lukoil group. These products symbolize world-class quality and reliability. At the same time, this is a very affordable price segment;
• Quicksilver– an Australian brand specializing in the production of oils and cosmetics for various vehicles. The products successfully extend the service life of engines and contain unique additive packages;
• TOHATSU– the Japanese corporation also pleases with the consistently high quality of oils and cosmetics. We can talk about the protection of motors when operating in aggressive environments, protection from oxidation, corrosion, and a significant increase in service life, which is confirmed by numerous reviews;
• Yamalube- this is real world brand, known almost everywhere. It produces high-quality products for internal combustion engines, which successfully work in a wide variety of applications. power plants. All oils undergo multi-stage laboratory tests.

An overview of oils for outboard engines and tips for choosing them are shown in the video:

The engine is the main mechanical unit in a boat motor. It determines the performance of the equipment, the correct operation and the length of its service life. Its functioning directly depends on the oil used for 2-stroke outboard engines. Therefore, the choice of this component must be taken with special responsibility.

Types of mixtures

There are many offers on the market from various manufacturers. Each oil for two-stroke engines of outboard motors has individual characteristics, pros and cons. The entire range is divided into 2 main classes:

• synthetic;
• mineral.

It should be noted that this is not the entire list of types of oils for two-stroke outboard engines, but they are used most in demand. The product differences are: different composition, molecular structure, and the similarities lie in the stability of the components. For 2-stroke outboard motors, the most preferable is synthetic lubricants. This factor is justified by the possibility of maintaining viscosity at different temperatures. This has a positive effect on the durability of the engine and its components.

Such products are allowed to be used after mineral ones. But if an unknown consistency was poured into the engine, it must be drained and flushed. The mineral product stands out for its budget price. In addition, the reduction in material consumption should be highlighted. But design features Outboard motors of different brands are not designed to work with a liquid consistency, so users will often encounter leaks.

Oil requirements

To determine which oil is best suited for the application, you first need to understand the requirements for this component. The oily product performs the following functions:

• increasing the service life of the power unit;
• heat removal from mechanical components;
• preventing friction of working mechanisms;
• ensuring safety from external adverse influences.

The main quality criterion is the presence of a certificate of compliance with international or state criteria. All products for 2-stroke outboard motors are individually marked TCW3. Such oily compositions do not contain additives containing metalanion compounds. If a low-quality product is used, carbon deposits will form on individual engine components. This will lead to rapid wear and tear on the mechanisms and their breakdown.

Rating of the best oils for 2-stroke outboard engines

With the abundance of oils for outboard motors, an inexperienced consumer can easily get confused. But to choose the most best option for use, it is recommended to use the already established rating of oils for 2-stroke outboard engines.

Motul Outboard Synth

The synthetic Motul 2T refill product is considered a product latest generation. This option is perfect both for engines with an automated mixing system, and for units where it is necessary to pre-dilute the consistency manually. Thanks to high quality Motul for 2T outboard motors will keep all mechanical components in their original condition for a long time. Motul oil was produced taking into account NMMA TCW3, RL56623, APITSC4 standards.

Motul Outboard Synth

Brief parameters:

The synthetic fluid of the Motul-Sport classification is based on 100 percent esters. The manufacturer guarantees a significant reduction in friction force and high performance parameters. The price of the product does not exceed 1800 rubles.

Lukoil 2T oil

Lukoil is intended for use as an additional component in the preparation of a fuel-oil mixture for both water engines and engines of small equipment such as snowmobiles, chainsaws, motorcycles, etc. Reduced level Ash content is a guarantee of a long service life of the spark plug. It is also often used to lubricate gas power units and compressors.

Lukoil 2T

Based on numerous reviews, a list of the main advantages of this product has been formed. trademark. The advantages include long-term protection of the power unit, temperature stability, good parameters when used in the cold season, reduced volatility. The cost of a 4-liter container with mineral filling is 540 rubles.

VIDEO: Motul or Lukoil?

The Quicksilver brand produces two series of motor oils for units - Premium and Premium Plus. This product was manufactured specifically for two-stroke power devices, protecting them from external influences under extreme operating conditions.

Quicksilver Premium 2-Cycle Outboard

A synthesized product with the addition of a set of special additives has a positive effect on the service life of the two-stroke working body. The fluid is used for equipment with low or medium power rating. But here it should be remembered that the consistency is used only under normal operating conditions without extreme temperatures. The product is made according to the TCW3 standard.

Separately, it should be noted that the constituent elements maximally suppress the likelihood of oxidation of parts or the formation of corrosion. Quicksilver has good cleaning ability, due to which the engine will always remain clean and free of dirt. This is a big advantage because it is quite rare.

The capacity of the container is 4 liters, but there are also 1-2 liter variations. The mixture is used not only for boat equipment, but also for snowmobiles, ATVs, gasoline saws and other motor vehicles with liquid or air system cooling. The price for a 1-liter container is 650 rubles.

Luxe TC-W3

Delfin Industry is the first company to release Russian market motor oils specifically for two-stroke outboard engines. In addition to the fact that this sample is cheaper than most brands, its quality composition is much better than the industry standard TC-W3, developed back in 1991.

Options:

According to customer reviews, Luxe TC-W3 prevents the formation of deposits and mixes easily with fuel. It is used in a mixture with fuel in a ratio of 1:100. Please note that the TC-W3 standard defines a list of requirements, the main of which is the absence of anti-wear and extreme pressure additives that contain heavy metals. These additives have been replaced with biodegradable ones, which limits engine power. At more than 6000, such oil will no longer help. Price 1 liter 249 rub.

Synthetic oil German manufacturer consists of basic components and a set of additives. Can be used for all 2-stroke engines, regardless of the cooling system - air or liquid. Biodegradable composition, that is, there are no anti-wear and extreme pressure additives based on heavy metals. This is consistent with the TC-W3 standard, but excludes applications for engines with maximum torque greater than 6000 rpm.

LIQUI MOLY Marine Fully Synthetic 2T

The product has the advantage of reducing the flash point to 120°C (compared to 240°C for Motul). This, on the one hand, is more profitable, since the oil burns completely even in a cold engine. On the other hand, it increases the consumption of the product, respectively, the concentration is 1:75. Considering the already considerable price - 1780 rubles. for 1 liter, the feasibility of its use is a big question.

Which oil should you choose?

Objectively, it is impossible to name the ideal or the worst oil. Everyone has how positive points, and negative. The most important thing is to buy a product taking into account the engine cycle and the availability of FC-W approval.

Please note the following:

1. For small-capacity four stroke engine choose oils with low viscosity.
2. Synthetics are purchased only if constant use is planned throughout the season. Even if the required volume is not exhausted, during seasonal conservation all working fluids are drained.
3. Synthetics are recommended for use specifically for two-stroke engines due to the minimum concentration, since the engine always runs at high speeds.
4. Even if you choose an inexpensive Chinese outboard motor, use high-quality oil - cheap components wear out faster, therefore, they need more reliable protection from wear. Of course, this is not a reason to use low-grade oil for expensive “Japanese” products, but in any case there is no need to save money. The lower the quality of the oil, the faster the engine life is consumed, regardless of the country of the engine manufacturer.

VIDEO: Test of several brands of oils for two-stroke outboard engines

For several years now, many owners of two-stroke engines continue to argue about what oil should be used on two-stroke engines, old and new - synthetic or mineral. Let's try to figure it out.

First, a couple of examples from life. One acquaintance, having bought a new foreign-made engine, persistently fed it “MS-20”, relying on extensive experience in operating Soviet-made engines. It’s good that I used AI-95 gasoline. The engine lived without problems for two seasons, but on the third it began to malfunction. After some operations on setting up the carburetor, ignition system and replacing spark plugs, this bright man finally decided to “open up” the engine. It showed that the combustion chamber was literally clogged with carbon deposits, and the rings were, as they say, “stuck.” All this was implied before disassembly, but I wanted to make sure and convince the owner. The main problem of the owner, who almost killed the engine (after resuscitation, the engine continues to live today), was that he used the recommended AI-95 gasoline, but, not understanding the advice on oil, he decided to take the best of what he knew .

Here's another example. Let's say someone with good motorboating experience decided one day that he no longer wanted to deal with motors. domestic production and, naturally, I bought a “foreign car”, for which I spent a long time selecting oil for two-stroke engines. For some reason, this person did not want to buy “pre-dissolved” oil, which can simply be poured into a can of gasoline in the required proportion, shaken and used as directed. To the question: “Why?” the answer was the following: “I don’t trust it, because it does not lubricate the engine elements well, because it has already been dissolved.”

I hope there are enough examples from the life of domestic elders for now. Let's return to mineral water and synthetics.

So what is the difference between mineral oil and synthetic oil, other than the retail price?

The differences are at the core. That is, the composition of the additives in them may be identical, but the base is different. In mineral oil it is, roughly speaking and without delving into chemistry, from petroleum, and in synthetic oil it is from specially obtained chemical elements, which chemists call olefin polymers, esters, ethers, alcohols, etc. Different manufacturers use different formulations and bases. Oils for two-stroke engines, which contain up to 30% synthetic components, are produced by many companies. Moreover, their packaging may say “Synthetic”. On the one hand, this marketing ploy and an indication that the oil actually contains a synthetic component, on the other hand, this inscription can often mean that the flash point of the oil and its lubricating properties are improved compared to “purely mineral” oil. The oil on the packaging that says “Fully Synthetic” most likely has a 100% synthetic base. Sometimes manufacturers are cunning by mixing in a certain amount of mineral. True, this does not affect the quality of the oil very much, except that its biodegradability becomes slightly lower and a little more harmful emissions are generated. But it’s still a shame - you pay 100 percent synthetic oil, and you get, for example, 92 or 89 percent...

Fully synthetic oil for two-stroke engines, i.e., consisting of 100% olefins and other elements, appeared for two main reasons: due to the demands of environmentalists and the birth of powerful and highly loaded engines, in particular, with direct fuel injection systems. Powerful modern ones require an oil that, firstly, has good fluidity, which is important for successful operation in automix systems; secondly, it is capable of lubricating engine elements well and at the same time burning quickly and as completely as possible; and, finally, thirdly, quickly decompose in the open air and be as little harmful as possible to microorganisms. A synthetic oil base makes it possible to satisfy the listed requirements, although not completely, but more successfully than a mineral one, which has only part of the mineral base - the so-called “semi-synthetic”. In short, synthetic-based oil is more stable and convenient.

Today, all oil manufacturers are slowly switching to synthetics, at least those who make oils for engine manufacturers. Oil is becoming more expensive, but the technology for producing olefins and analogues, if not becoming cheaper, remains at the same level. However, in retail, “synthetic” remains more expensive than “mineral”.

The following picture emerges: new types of oils are automatically better than the previous ones. Of course, in their niches. In this case, the “ascending” principle works, i.e. old motor You can relatively painlessly fill in fully synthetic oil, but you cannot fill a new two-stroke engine with injection with oil intended for “classic” two-stroke engines.

So what to do and what to buy? You need to buy what the motor manufacturer recommends. If the “manual” states that you should fill in oil that meets the TC-W3 standard and there are no other comments, then you can use any mineral oil that meets this standard and is trustworthy.

Almost all modern two-stroke engines without an “automix” system can operate successfully, without much harm, on modern mineral oil, which has a low cost. In engines with an “automix” or other system, but supplying oil to the crank chamber through special device, you can also use mineral oils, but only those intended for automatic supply systems, of course, if the manual does not indicate that special oil should be used.

Manufacturer of modern injection two-stroke engines and two-stroke engines high power indicates the inadmissibility of using oils other than those specified in the instruction manual, and this must be strictly adhered to. They require fully synthetic oil, because the engines were made with it in mind.

“Synthetics”, which, as already mentioned, has greater fluidity than mineral water, which is important for a “point” oil supply system, as well as improved lubricating properties, creates a “stable” film on the engine elements that prevents dry friction even in critical cases. The higher the engine load, the greater the likelihood of critical moments occurring, in our case - oil starvation.

There is an opinion that “synthetics” do not work well in motors with plain bearings. However, although special studies on this topic have not been conducted (or there is no available information about them), practical experience in the use of synthetic oil suggests that it is as friendly with sliding bearings as mineral water, mainly due to its penetrating properties and the ability to create a tear-resistant film.

So, after all, is it possible to use synthetic oil in “simple two-stroke engines”? In principle, yes, the engine will not get any worse, but sometimes, especially at the time of start-up and in mode maximum speed, maybe even better. There will also be less deposits in the combustion chamber. At the same time, good mineral oil, which has a low retail price, will allow the engine to last the hours set by the manufacturer, i.e., the resource. Therefore, everyone must decide for themselves.

What's the result? Read the instructions and, if the manufacturer recommends using mineral oil, then the use of synthetic oil is not prohibited, however, due to high cost

and is not “encouraged.” If the use of a specific synthetic oil is recommended, then mineral oil can no longer be used, even the corresponding TC-W3 - for many reasons it will not suit the lubrication system of a particular engine.

And lastly: on long trips on motorboats, it makes sense to take with you a jar of synthetic oil, which can be mixed with all types of oils for two-stroke engines. It is convenient and can help in difficult times, if not for you, then for others who find themselves in a difficult situation. When you purchase a boat, the first thing you need to think about is what engine is best suited for its engine, so that it can work properly for a long time and does not need repairs. Every owner of a PVC boat will face this problem and should take this seriously, since the proper operation of the boat’s engine will depend on the quality of the selected oil.

There are usually two types of oils to choose from:

• synthetic;
• mineral.

In order to make the most the right purchase, you need to imagine how these oils differ from each other, what their advantages and disadvantages are.

The main difference between these oils, of course, is their molecular structure, that is, you will have to look for differences in the very basis

.

It is worth noting that synthetic oils are considered very stable due to the fact that they are built with already defined specified parameters. Such oils are most often purchased specifically for boats.

Also, such oil is considered very convenient, since even if mineral oil was used before, synthetic oil can easily replace it. However, if you do not know for sure what kind of oil was in the boat, it is best to use first flushing oil, and only then synthetic.

Stability in chemical composition synthetic oil means the most safe mode motor operation. That is, there will not be any transformations in it that can quite significantly change the operating time of the motor and its general characteristics.

So, when choosing a synthetic oil, you can be sure that its viscosity will be the same over a different temperature range. This phenomenon will significantly determine how quickly the boat can start, for example, in the cold, as well as the stability of the motor at extremely high temperatures, and when it is forced to work in difficult conditions.

In addition, synthetic oil is much more fluid than any other oils, which is another positive factor. The excellent fluidity of the oil is also ensured by its composition, which is reliable and tested with the help of highly qualified specialists, which is incomparable to the fluidity of mineral oil, and is also famous for its penetrating ability.

Synthetic oil for two-stroke outboard engines

If you haven't used synthetic oil before, there can be real problems when switching to synthetic oil.

Most often, they are detected more critically if cheap and non-existent ones were previously used. quality oils, and recommendations for changing the oil were often not followed, and any foreign substances were observed to get into it. Then the motor will begin to deteriorate due to accumulated in it harmful deposits. In this case, you may notice cracking of the seals in the motor.

If you use mineral oil, then such deposits will peel off and come out gradually, but if you use synthetic oil, the deposits, due to its high fluidity, will be washed out all at once, which can be dangerous, since the oil receiver mesh may simply become clogged because of this.

will happen oil starvation and, as a result, we will get a damaged motor, no longer suitable for work or in need of expensive repairs.

How to choose oil for two-stroke outboard engines

It is best to use synthetic oil from the very beginning, otherwise switching to it after any other foreign oils can result in disastrous consequences for the PVC boat motor.

So, let's look at when you can't use synthetic oil:

• deposits are observed in the engine;
• the sealing elements are no longer elastic;
• during the “break-in” period;
• The engine has already been repaired.

In any other cases, synthetic oil will be an excellent option for your engine and guarantees it protection, thanks to which it can work for a long time and efficiently without any breakdowns.

Main characteristics of oils for 2-stroke outboard engines

If you have just purchased a boat, then you should “break it in”. For this task, mineral oil is best suited and only after that can you start using synthetic oil. Then the motor on your boat can serve you for a really long time.

However, if you decide to switch to “synthetics”, but something goes wrong, you can always independently assess the damage in order to apply necessary actions, which will not allow the boat engine to fail.

Grade:

• assessment of the condition of the engine (presence of pronounced defects or seals, oil leakage);
• the presence of deposits in the engine (here it will be enough to simply flush the oil supply system);
• sebaceous seals have ceased to be elastic (synthetics are not recommended; it is better to use them after proper repairs and “breaking in the engine”).

If you still doubt whether your engine can withstand synthetic oil, you can start using “semi-synthetics” first.

Which oil to choose for outboard motors

The most popular boat motors:

• Suzuki;
• Yamaha;
• tohatsu.

Individual oil should be selected for these engines. For a Suzuki engine, synthetic oil is quite suitable, which costs no more than five hundred rubles per liter.

For Yamaha, you can even use car oil, since this motor considered stronger. Such oil costs differently, you can find it quite cheap, from 300 rubles, or very expensive, since they sell oils for Yamaha for 2000 rubles.

Mineral oils in the case of a Tohatsu engine or any mixtures made with the addition automobile oils It's better not to use it. This engine is weaker than the Yamaha, so it is best to buy good synthetic oil, which costs around seven hundred rubles.

Motul oil for two-stroke outboard engines

Motul is considered a fairly popular oil for boats. Such oil burns completely in the engine, which does not create any waste that can subsequently clog the oil network, which will lead to an unpleasant breakdown in the future.

This oil works on the principle of mixing. That is, it enters the combustion chamber together with the fuel, since two-stroke outboard engines always have a “combined” mixing system.

How long will a two-stroke outboard motor last without oil?

The engine can work without oil, but it won’t last long. That is, the engine without oil will work at idle speed. This happens because even after the oil is removed, an oil film remains and until it is completely exhausted, the engine will be able to work.

The oil protects the motor from friction while the piston moves inside the motor. Naturally, the engine will stop working when the oil runs out completely and most likely may even become unusable.

Therefore, you need to choose the right oil for your boat, taking into account all its characteristics. Only in this case powerboat will be able to serve its owner for a long time and move around the most dangerous places on the river.

When faced with a choice before buying oil, you can always consult with more enlightened boat owners who have been using such a vehicle for a long time. After all, we all know that the selection of any part occurs by trial and error, and most often this is the best option, since you can evaluate each oil and choose the one that will suit your boat best.
