What kind of oil to pour into a Subaru Forester. Do-it-yourself oil change in a Subaru Forester engine. Other products for Subaru

Today every person knows that car engines work efficiently and for a long time only thanks to engine oil. It ensures constant lubrication of engine parts, and also performs several more essential functions. Therefore, engines operate for a long time without major repairs, often driving 150–200 thousand kilometers. Subaru oil belongs precisely to this type of product, which with its quality characteristics provides long life to the motor.

A little about the product

Motor oil for Subaru is produced by the Japanese corporation IDEMITSU. This company has four oil refineries in Japan. Their own wells supply them with raw materials, so production cycle can be considered complete. That is, Idemitsu produces oil, processes it and supplies the products of this processing to the market.

Oil produced under the Subaru brand is distributed jointly with Fuji Heavy Industries. Thanks to an extensive transport network and optimal logistics, it is possible to slightly reduce the final cost of the product.

Subaru engine oil 0w20, as well as 5W30, was developed specifically for the engines of this company. They have a specific arrangement of cylinders - in a horizontal plane, opposite each other. Such engines are called “horizontally opposed”. These are what all Subaru cars are equipped with. Due to the design features, these power units are so capricious in the choice of lubricants.

A distinctive feature of Subaru oils is their exceptional cooling capabilities. They service power units running on gasoline. Viscosity corresponds to international SAE standard.

When running in new car and during the initial period of operation, original oil with a minimum viscosity index should be used, that is, SUBARU MOTOR OIL SM 0W20. If the car has passed sufficient quantity kilometers - from 50 thousand and above, you can already switch to a higher viscosity, 5W30. Moreover, such a lubricant is intended for severe operating conditions, and in Russia there are just such. It all depends on how much consumption increases lubricant minimum viscosity. If the engine begins to use liters of it, this is that threshold.

Features of 0W20 oils

Subaru brand engine oil of minimum viscosity is intended only for boxer engines. The main purpose is small-displacement gasoline engines with SOHS gas distribution systems. This is an all-season synthetic product, which is based on a liquid obtained by hydrocracking using NS technology. There is a synthetic additive obtained from light hydrocarbons. The additive package is unique, intended exclusively for Subaru. Protects the motor very well, providing the following functions:

The base has a very good viscosity index, starting from 165. It is not inferior to fully synthetic products from other manufacturers. Therefore, IDEMITSU classifies oils for Subaru as synthetic, although hydrocracking is still not synthetic. The base contains no aromatic and sulfur compounds, which indicates high stability composition.

The lubricant has been tested in wide range temperatures, while showing amazing stability of its basic qualities. According to the SAE standard, at 0W20 the oil composition retains all its characteristics and allows the engine to crank at low temperatures down to -30°C. The color of the oil composition is green, which indicates a large amount of molybdenum.

Molybdenum significantly prevents wear of parts power unit, prolonging his life.

According to API standard, the oil corresponds to categories SN/SM/SL. This means that the phosphorus content in the composition is minimal. This approach is necessary for the long-term operation of systems for neutralizing harmful emissions, which have exhaust gas. The oil composition is comprehensively energy-saving. Can be used for both naturally aspirated and turbocharged engines. Has high resistance to oxidation, prevents wear processes that cause premature aging power unit parts.

Besides, engine oil SUBARU MOTOR OIL SM 0W20 complies with the American-Japanese ILSAC certification standard. The lubricant composition is assigned to categories GF3/GF4/GF5. This means that the product must prevent the formation of various types of sludge, provide high level protection piston group, and regarding forced engines and turbochargers, protect against deposits formed at high temperatures.

The oil has increased compatibility with the materials from which oil seals and various gaskets are made. Thanks to good oxidation resistance, it does not age for a long time, providing an extended interval between replacements. Well protects engines that can run on biofuels containing ethanol. For all other characteristics, GF5 corresponds to class SN of the API standard, GF4 - SM, GF3 - SL, respectively.

Many drivers complain that their engines consume this lubricant composition liters. Moreover, both worn-out and practically new power units are susceptible to this “disease”. This is due to certain disadvantages of boxer engines from Subaru. The fact is that aluminum blocks cylinders have cast iron sleeves. Cast iron and aluminum have different coefficients of thermal expansion. This drawback causes the cylinders to take on an ellipsoidal shape. Oil scraper rings the pistons also “lie down”. All this together leads to the fact that lubricant leaks into the combustion chambers. This is the reason for the expense. This problem can be “treated” in only one way - by switching to a more viscous composition 5W30.

Oil compositions 5W30

The oil composition SUBARU MOTOR OIL SM 5W30 is not new development. The product has been sold on the market for a long time and has won its army of fans. Subaru positions it as a lubricant that should be used when... difficult conditions operation. By default, the manufacturer still recommends using 0W20, especially on early stage run until all engine parts have become accustomed to each other.

Naturally, the product meets all standards regarding viscosity and other characteristics. Recommended for use in temperate climates where there is no severe frosts. According to international classifiers, it has the same categories as 0W20. The base is not synthetic in the direct sense of the word, because it is obtained from oil by hydrocracking using HC technology.

Classic, or 100%, synthetics are synthesized from gas, that is, a light hydrocarbon substance. This oil is called PAO, or polyalphaolefin. Why is hydrocracking equated with synthetics? Because the viscosity index of hydrocracking oils is comparable to PAO. This means that the substance is stable over a wide temperature range without losing its basic qualities. But still PJSC thermal-oxidative stability higher.

During the process of catalytic biochemical treatment, oil goes through several stages of purification. First, fuel oil is obtained, then it is distilled in a vacuum. Thus, it is possible to obtain the heaviest fractions, which are the raw material for further processing and purification. The main goal is to remove as much as possible sulfur and solid paraffins, various organic acids, resins, and other polycyclic compounds. They are precisely the cause of the formation of varnish deposits, corrosion and carbon deposits in the engine, being a catalyst for these processes.

We can say that hydrocracking is a technology for maximum purification of mineral oils from all of the above impurities. In this process, several reactions occur in parallel and simultaneously. The result is the purest possible product, which, by the way, is even used to make Johnson’s Vavu baby oil. Some companies classify hydrocracking products as mineral oils, some, like IDEMITSU, are synthetic. In fact, this is a completely separate class of products, which is equal in quality to synthetics, but is much cheaper.

The quality of oils produced for Subaru is worthy of praise. It hasn't happened yet negative reviews about them, except in cases where careless motorists have used these products for other purposes - after all, they are only suitable for boxer engines Japanese manufacturer.

Other products for Subaru

In addition to the above motor oils, transmission lubricants are also produced. These include Subaru ATF for automatic transmissions. This is a high-quality, expensive semi-synthetic product, specially tailored for Subarov automatic machines. A special oil is also produced for power steering.

Despite the fact that all these products are intended for cars from a Japanese manufacturer, they can also be used for other vehicles, as long as the lubricant characteristics are the same. True, few experimenters do this for the reason high cost these products.

3.04.2018

Despite the fact that a larger number of Subaru Forester cars are sold in our country through secondary market, the model has not lost its popularity over the years. This trend is due to excellent driving characteristics, high quality assembly and stylish, ergonomic design of everything model range Subaru, as well as wide possibilities in cross-country ability, thanks to systems all-wheel drive wheels Among service questions, the most frequently asked question is which Forester oil to pour into the engine, gearbox, and gearbox. rear axle and not by chance. From the right choice and compliance with replacement deadlines depends on the service life of these units, and repairing them in the event of breakdowns is usually difficult and expensive.

To the engine

All cars of the brand are equipped with boxer power units, which are very demanding on the quality of engine oil. In addition, due to incorrectly selected lubricant, such a motor experiences the so-called “ oil starvation" This phenomenon negatively affects its performance, causes overheating and increased wear basic elements.

For the cold period - 5W-30,
universal - 10W-40 (10W-30),
for hot periods - 20W-50;

The use of liquid motor oils is usually contraindicated because main feature boxer engine is increased load on the crankshaft while it is running. Insufficient viscosity of the lubricating fluid leads to the formation of nicks on interacting parts. This causes their critical wear and causes complex and expensive repairs. Besides this, too liquid oil destructive for engines with high mileage.

When to change Subaru Forester engine oil?

The manufacturer recommends a power unit lubrication interval every 10 thousand kilometers. On new cars, the engine oil is changed after the end of the break-in period, which, depending on the intensity of use, averages 5 thousand km. The only thing you should not forget about when performing this procedure is to completely drain the old lubricant, then rinse the power unit and replace the filter element.

An important and mandatory point: the power unit must be filled with the exact oil that was originally used in it. For example, if the engine was synthetic oil Forester, accordingly, when replacing, this type should be used, but not mineral or semi-synthetic. In the case when the choice fell on a lubricating fluid of a different brand, before pouring it into the engine, it is necessary to completely flush it. After this, you need to fill the new one to a level that will exceed zero mark on the dipstick by about 3-5 mm, and start the engine so that it runs for about 10-15 minutes. Next, drain the filled oil, change the filter and refill the lubricating fluid to the required level.

Automatic transmission oil

What kind of oil is used in Subaru Forester automatic transmission? This question is one of the most popular on forums dedicated to this model.

Special transmission fluid in automatic transmissions gear is necessary to ensure the transmission of torque from the power unit through a special torque converter. In addition, it is needed for lubrication and cooling of interacting elements. Naturally, its resource is not endless. With time transmission oil loses its properties and becomes completely unsuitable for further use. In this case it is necessary urgent replacement transmission fluid, otherwise we should expect the most disastrous consequences for the automatic transmission.

Prerequisites for replacement working fluid in the Forester automatic there are extraneous noises when switching positions, heavy selector travel, incorrect gear shifting. All this indicates insufficient level lubricating fluid in the automatic transmission, or its unsatisfactory condition.

Forester pan drain plug

The manufacturer has established a schedule for replacing transmission fluid, which is 100 thousand kilometers. In general, the actual life of the oil in an automatic transmission corresponds to the service life of the vehicle. But in reality the situation is somewhat different. There are a number of reasons why an urgent oil change is indicated. Among them:

The presence of a leak on the automatic transmission housing as a result of mechanical damage.
Incorrect operation of the box.
Repair activities.
Change in oil color and presence of a characteristic, burnt odor.

The type of oil used in the automatic transmission is indicated in the technical book for the car. We recommend using it. To replace you will need about 9 liters high quality oil. In addition to the original lubricating fluid recommended by the manufacturer, owners often use Dexron oils III, Liqui Moly, Castrol ATF Multivinicle and Idemitsu ATF HP.

On this moment The Subaru Forester car is already in its 4th generation. This car is constantly popular among motorists and sales volumes are only increasing. The car has several versions with turbocharged and naturally aspirated power units.

Due to the wide variety of models, many motorists have the question of which engine oil is best for Subaru Forester 2.0. To find the correct answer to the question posed, you need to study the main specifications of this car.

Summarizing

Which engine oil for Subaru Forester 2.0 is better largely depends on the conditions in which the car will be operated. First of all, this concerns the ambient temperature. When choosing oil, you need to take into account the engine type and year of manufacture. All developers come to one conclusion that the best lubricant for Subaru Forester 2.0 is Subaru oils with different variations in viscosity level and temperature conditions of use.

The selection of lubricant must be made taking into account the requirements of the vehicle manufacturer. Using unsuitable engine oil for Subaru Forester can lead to engine failure. The article provides data on oil tolerances from the manufacturer's operating instructions for Subaru car Forester.

Engine oil recommended by the vehicle manufacturer provides stable work engine, extends the life of the power unit. After looking at the instructions for the Subaru Forester, we found not only the recommended viscosity grade according to SAE, but also the necessary marking according to API classifications and ACEA, as well as the type of fluids to be used under severe operating conditions vehicle and in case of adding lubricant.
When selecting a car oil, keep in mind: an increase in oil viscosity leads to an increase in fuel consumption. Low-thickness lubricants provide reduced fuel consumption when low temperatures, but in hot weather it is better to use thicker lubricants; they liquefy more slowly and protect the engine from overheating. Pay attention to the tolerances; it is recommended to use original SUBARU oils.
