12 best engine oils for Subaru Forester

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

The popular boxer station wagon is already available in the fourth generation – and he is already eight years old, so a large number “Forester” has already managed to get out of warranty, and for their owners it is logical to refuse expensive service in dealership technical centers and original engine oil. Traditionally, start by choosing replacements with factory operating instructions – it offers three options:

  1. For a naturally aspirated gasoline engine use engine oils with viscosity SAE 0W-20, i.e. our the choice is directly limited by low-viscosity “energy-saving” oils, which confirms and instruction – it requires that the oil has API SM / SN certification with mandatory inscription Energy conserving on the label or had the ILSAC quality class GF-4 / GF-5.
  2. For a gas turbo engine, as expected, oil with higher high viscosity is required – SAE 5W-30 with the same requirements for quality classes. In the northern regions Naturally, it makes sense for Russia to talk about choosing SAE oils 0W-30.
  3. Diesel Foresters require the use of SAE oil 0W-30 strictly in the presence of ACEA C2 or C3.
  4. At the last moment, let’s take a closer look. The thing is the fact that oils of classes C2 and C3 have a serious difference in HTHS – at the same SAE index C2 oil at elevated temperatures and loads will have lower viscosity than C3 oil. Naturally, under such conditions, under other things equal ACEA C3 oil will provide more reliable protection engine – well, since the plant allows the use of both oils classes, we will choose more viscous oils when choosing C3.

The best oils for Subaru Forester with atmospheric gasoline engine

Shell Helix Ultra SN 0W-20

Rating: 4.9

SHELL Helix Ultra SN 0W-20

Oil complies with API SN quality class, has ILSAC class GF-5 and desired viscosity, so Subaru’s formal requirements for atmospheric gasoline Forester fully complies. In sheet Shell specifications indicate decent temperature solidification (-48 degrees), high temperature viscosity at the same time makes 8.8 mm2 / s, taking into account the declared index viscosity 174 oil can be called “liquid” at high heat load, but fully consistent with the requirements of the standard.

Laboratory analysis gives even lower temperature solidification: -54 ° C. Break with Subaru Original Engine Oil (see below) – 11 degrees, and this is a very serious difference, especially, if the battery is no longer new: where the original oil the starter will already begin to have difficulty with normal scrolling crankshaft, Shell will start the engine easier. Alkaline oil analysis – 9 mg KOH / g, the declared high temperature viscosity is also overlaps real, almost at the upper boundary requirements of the standard. Collectively, oil can be called potentially high-resource. Spectral analysis indicates use as base oil GTL is not hydrocracking oil, which is another plus in terms of stability properties when operating a car.

Given the usually short life of low viscosity oils, tests It’s wise to do mining at around 8 thousand kilometers run. Here Shell vividly demonstrates the advantages of the GTL base over hydrocracking: for this run it maintains normal high temperature viscosity and high alkaline number, therefore, such a run is normal for him, and you can talk about the reality of replacement periods of 10-12 thousand kilometers, this very good result. In this four-liter canister Shell costs more than a thousand rubles cheaper than the original oil, which is worse in terms of basic characteristics and resource. To cut intervals make sense only on cars with six-digit mileage – Under such conditions, the alkaline number of oil falls faster. therefore Shell victory and unequivocal recommendation from our experts more what is logical.

Advantages

  • Very low pour point
  • High alkaline number
  • A large resource that allows not to reduce the time of replacement

disadvantages

  • High evaporation, but within reason

IDEMITSU Zepro Eco Medalist 0W-20

Rating: 4.8

IDEMITSU Zepro Eco Medalist 0W-20

Idemitsu oils are popular largely due to the presence in their the line of “typically Japanese” – low-viscosity and with certification in class quality ILSAC GF-5. Among them, Subaru meets the requirements Zepro Eco Medalist, at a price level almost comparable to Shell. Moreover, they are comparable not only in price: Idemitsu also demonstrates excellent temperature during laboratory analysis of samples solidification at -52 degrees, promising a good resource and high engine cleanliness alkaline number 8.8 mg KOH / g High temperature its viscosity is slightly less than that of Shell (8.3 mm2 / s), but in practice this difference is imperceptible. Index the viscosity for hydrocracking oil is high – 214. The analysis does not the best way was only ash content, exceeding 1 percent: judging it’s all due to an increase in alkaline number, because it’s for the sake of reducing ash that they have to sacrifice to all world manufacturers of motor oils.

Unfortunately, the control analysis of mining samples leads to losing to idemitsu versus shell and at the same time stressing the difference between HC oils and GTL oils. Oil viscosity stability good but alkaline number falling to the lower limit of requirements standard at seven thousandth mark (with moderate engine mileage, note), definitely indicates that this particular run it is necessary when using Idemitsu to accept as an interservice. Shell will be able to work without losing critical properties on several thousand kilometers more. It is worth noting that markers engine wear in waste oil at a minimum allows us to talk about truly effective protection against wear and tear.

Advantages

  • Attractive price
  • Good viscosity stability
  • Excellent low temperature properties

disadvantages

  • Reduced service interval

G-Energy Far East 0W-20

Rating: 4.7

G-Energy Far East 0W-20

Domestic engine oil designed specifically for specific Japanese requirements (SAE 0W-20, API SN ILSAC GF-5) – one of the most affordable in our market. At a price of four cans within 1700 rubles, it is quite possible for him to forgive the expected reduction of the service interval. And the need for this already felt according to the declared alkaline number (7.9 mg KOH / g – this smaller than Shell and Idemitsu). High temperature viscosity manufacturer’s data is 8.3 mm2 / s, and the temperature solidification – minus 45 degrees. Not the best characteristics, but not forget that we compare oils with a decent price difference.

Real analysis of a fresh sample of oil makes it clear what concerns low resource fair. Alkaline oil by measurement – 7.75 mg KOH / g, high temperature viscosity just above 8 mm2 / s. At the same time, the pour point is lower than stated (-48 degrees) – perhaps in a particular batch the share is slightly reduced thickener, in general, we can talk about normal compliance statements. Since base oil is inevitable at this price hydrocracking, we summarize: do not change this oil less often than 7-8 thousand kilometers, like the more expensive Idemitsu. But since Idemitsu has a certain handicap in the form of a high alkaline number, G-Energy goes lower in the rating: with an increase in crankcase gas breakthrough through rings as the motor wears, when using Idemitsu sour fuel will “age” more slowly.

Advantages

  • Low price with wide availability in the retail network and on Gazprom branded gas stations
  • Good low temperature properties

disadvantages

  • Average resource characteristics

SUBARU SN 0W-20

Rating: 4.6

SUBARU SN 0W-20

We prefer to take in the presence of laboratory tests (since automakers themselves usually do not publish characteristics of its “original” oils) factory engine oils fillings as a kind of standard for comparison: in many cases they really are the best choice for the engine. However, at a price of 3800 rubles per canister 4 liters (at the time writing an article) original Subaru oil for atmospheric Forester is already losing rating points, given that such “environmentally friendly” and “energy-saving” oils really stand mileage in the region of 7-8 thousand, and use expensive “native” oil brands are disadvantageous.

In this case, nothing particularly impressive in hydrocracking oil (judging by the viscosity index having ester additives – this is partly explains the price) with the company logo on the canister is not. High temperature viscosity for the “twenty” is not bad – 8.4 mm2 / s (with tolerance of the standard 6.9-9.3 mm2 / s), an alkaline number at the level of half the cheaper G-Energy – 7.74 mg KOH / g The oil has a good margin to drop performance with mileage – normal life for such engine oils it will stand. However, an evaporation rate of 15% according to Noack is a lot, and pour point for oil with this viscosity class is not the most impressive: -43 degrees. Therefore, taking into account the price of the original oil Subaru for Forester – definitely not the best choice, it loses even to the cheapest oil in the ranking without offering nothing in return. The strangest thing is that the actual the manufacturer of original oil in the Russian market is Perm plant LLC “LLK-International” (read – “Lukoil”): price not can even justify the “import” origin.

Advantages

  • High alkaline number for this oil class
  • High viscosity index (over 220)
  • Good high temperature viscosity stability

disadvantages

  • High price
  • Not the best “winter” properties for SAE 0W-20

Best oils for Subaru Forester with gasoline turbo engine

Mobil 1 X1 5W-30

Rating: 4.9

Mobil 1 X1 5W-30

We can call this oil the best choice for heat-charged engines with supercharging. According to the declared quality classes it does not just fit into the requirements of Subaru, but also overlaps them: API declared the most stringent SN Plus at the moment, there is ILSAC GF-5 certification.

In this case, the real base number for the oil in the laboratory analysis high by the standards of its class: 9 mg KOH / g, high temperature viscosity for different samples gives an average 11.5 mm2 / s. For class SAE 5W-30 manufacturer at the same time was able to achieve excellent low temperature properties: pour point at -52 degrees even lower than what you can to expect, and you can talk about oil as a good option, even for cold regions of Russia. Mass fraction of sulfur – less than 0.2%, degree base oil cleaning high. Combined base oil itself, judging by the spectrogram and physical characteristics – to the main fraction of hydrocracking oil added GTL oil, present polyalphaolefins and alkyl naphthalenes. Thus the manufacturer successfully balanced the price and oil resource: samples, selected on the run 15 thousand, confirm that the reduction alkalinity, it’s only “beginning to approach” the lower bar of the standard, viscosity remaining within the limits specified for SAE 5W-30. Oil can definitely recommend, especially against the background of a more expensive and lower-quality “original” Subaru SN SAE 5W-30 – it again it was so pale that we decided not to include it at all rating.

Advantages

  • Excellent performance stability
  • High cleaning properties
  • Minimum waste consumption in a working engine
  • Above average low temperature properties for this class viscosity

disadvantages

  • Relatively high price (almost at the level of the original)

Motul 8100 Eco-lite 5W-30

Rating: 4.8

Motul 8100 Eco-lite 5W-30

An interesting version of engine oil, which, despite low viscosity and limited resource expected for ILSAC GF-5, done, on the contrary, with a clear bias of characteristics towards high temperatures. For turbocharged boxer engine Subaru this is a serious plus – although one cannot but note the high price of oil, traditional for Motul.

High temperature oil viscosity – 11.4 mm2 / s good stock on HTHS viscosity. Oil retains high strength films at extreme heat loads, saving liners, camshaft beds and turbocharger bearings. Alkaline number – 8.5 mg KOH / g, slightly less than Mobil 1 / Increased proportion thickeners in base hydrocracking oil, providing good high temperature properties, inevitably affected the temperature solidification: here Motul lost as much as 13 degrees. Therefore, if Mobil 1 can be called universal for all regions of Russia, then Motul in the north without a pre-heater will use less convenient.

Motul waste oil life tests withstands with dignity – the oil is able to withstand standard replacement intervals, remaining within the requirements of standards for viscosity and alkaline number. Depreciation based on metal content in the sample is minimal, which is logical – judging by all the same analyzes, in the composition used an effective additive based on molybdenum.

Advantages

  • High stability characteristics
  • Excellent protection for a warm turbo engine
  • Good cleaning properties
  • An increase in the proportion of thickener is also felt by the operation of the motor – it becomes noticeably quieter than on more “liquid” oil of the same class SAE viscosity

disadvantages

  • High price

Lukoil Genesis Armortech JP 5W-30

Rating: 4.7

Lukoil Genesis Armortech JP 5W-30

Given that on the canister with this oil you can see the same manufacturer information as on the original Subaru oil for Russian market, the price gap is particularly impressive: if for “original” will have to pay more than 3,500 rubles (for 4 liters), then for “unoriginal” from the same factory – about 1800. At the same time, Genesis oil Armortech JP, designed to meet the requirements of Japanese cars and having both the approvals we need (API SN and ILSAC GF-5), and The properties are very similar to the Subaru SN SAE 5W-30. Declared in technical documentation high temperature viscosity – 10.4 mm2 / s, pour point – minus 41 degrees: here, unlike Motul, they played on reducing the proportion of thickener, wishing to obtain low temperature properties important for Russia.

In a real analysis, both numbers are offset even lower: the oil freezes at a lower temperature, but at the same time slightly “thinner” than promised when working. Similarity with the original oil very high, but measured alkaline number at Lukoil (8.12 mg KOH / g) more than stated for the “native”.

As a result, given the price gap, Lukoil will definitely a more profitable replacement for the original oil – it doesn’t loses. In our ranking, it receives points below Mobil 1 and Motul only because of the worse in comparison with them high-temperature properties that under heavy loads and operation in the southern regions Russia is undesirable – at least it makes sense to reduce the intervals replacements.

Advantages

  • Oil is more than comparable to the original at half price
  • Decent base number
  • Good low temperature properties

disadvantages

  • Not the best high temperature viscosity

ENEOS Premium Touring 5W-30

Rating: 4.6

ENEOS Premium Touring 5W-30

Japanese oil is offered in the same price segment as Lukoil – an average four-liter canister will cost about 1800 rubles (at the time of writing). Declared specifications also not a record: high temperature viscosity at 10.69 mm2 / s, low alkaline number – 7.33 mg KOH / g. According to the pour point, declared as -36 degrees, ENEOS even loses to domestic oil – therefore, if Lukoil has the decrease in high temperature properties was partially justified by the best starting characteristics in the cold, then ENEOS in this regard loses.

According to laboratory analysis, the oil appears even slightly worse. expected: “shortage”, albeit small, there are both viscosity and alkalinity, pour point measured only as -34 degrees. For SAE 5W-30 oil, this is far from the best indicator. The only thing, what ENEOS could stand out is low volatility, but in the list When it comes to oil-critical properties, it is far from leading places, and Lukoil we will definitely call the best choice for the same money.

Advantages

  • In general, for its price, oil is not bad in terms of characteristics
  • Low volatility at high thermal loads reduce waste through the crankcase ventilation

disadvantages

  • High pour point
  • Small alkaline number

Best Subaru Forester Diesel Oils

Shell Helix Ultra ECT C2 / C3 0W-30

Rating: 4.9

Shell Helix Ultra ECT C2 / C3 0W-30

In this category, Shell is becoming a favorite of our experts. Even taking into account the fact that published by the company technical information is traditionally stingy: promised freezing point at -51 degree at a sufficiently high high-temperature viscosity of 11.9 mm2 / s, no alkaline data are given. However in The oil company directly indicates its high cleaning properties. in comparison with the requirements of the declared standards – this is exactly what primarily interested us, potentially promising high for medium-ash oils ACEA C3 alkalinity (which they usually have is at the level of 6-7 mg KOH / g, which in Russia forces to reduce service intervals).

Laboratory analysis brilliantly confirms our hypothesis: with alkaline number 8.81 mg KOH / g this oil is among the leaders on our market, in combination with the use of GTL base oil is guarantees a high resource of oil. True, ash content is oil. exceeded ACEA C3 requirements by several hundredths of a percent – but we cannot call this a real cause for claims for oil. The pour point of the test was -54 degrees, the content sulfur – less than 0.2%, volatility for low-viscosity oil is very good – 9.4% according to Noack. Before us is uniquely high-quality oil with excellent thermal stability and a long resource – we give it to him first place.

Advantages

  • Alkaline excellent for the class and high-quality PED base provides oil with a high real service life in engine
  • High viscosity stability
  • Good low temperature properties

disadvantages

  • Real high ash

Castrol Edge Turbo Diesel 0W-30

Rating: 4.8

Castrol Edge Turbo Diesel 0W-30

Castrol offers oil that competes with Shell loses mainly in price: four-liter canister passes the three thousandth mark. However, if there is a class ACEA C3 qualities in the list of characteristics it excellently showed yourself in the analysis. At high temperature viscosity 12.09 mm2 / s (which is close to the upper limit for SAE 0W-30) it at the same time has a pour point of -44 degrees: in comparison with Shell, the characteristics are more biased towards high temperatures, with tough exploitation, but in moderate frosts, we can advise you to choose Castrol. Alkaline number – 8.69 mg KOH / g, the oil is well compatible with high sulfur fuels, which confirms and analysis of mining – normal service interval Castrol can withstand sufficient alkalinity and viscosity. Sulfur less than 0.2% in oil, volatility at 8%, flash point 245 degrees – this clearly indicates the absence hydrocracking oil as part of the “base”, according to the spectrogram here used pure polyalphaolefin. With thermal stability and the oil will have no problems, the level of deposits in the engine it is able to keep to a minimum.

However, it is worth noting that if Shell is only a tiny fraction goes beyond the upper limit of ACEA C3 sulphate requirements ash content (0.06%), then Castrol the difference was as much as 0.2%. We, Of course, we understand that in practice, on the particulate filter resource fuel quality and condition itself are much stronger engine, but we can’t help but point out that a real oil sample unequivocally does not give the right to attribute it to mid-ash.

Advantages

  • Excellent viscosity stability and high base number
  • High cleaning properties
  • Low volatility

disadvantages

  • Ash failure versus ACEA C3 requirements
  • Not the best pour point for this class.

Mobil 1 ESP 0W30

Rating: 4.7

Mobil 1 ESP 0W30

Unlike Shell and Castrol, Mobil 1 fits perfectly into ACEA C3 ash requirements (0.6%), but expensive: claimed alkaline number – only 6.3 mg KOH / g, that is, before us is a typical resource-limited low-viscosity medium-ash oil, moreover more expensive and Shell, and Castrol. Diesel particulate filter maybe will last longer with him, but money for engine oil for this time will have to spend significantly more. Kinematic viscosity at 100 ° C declared very high – 12.2 mm2 / s, data stagnation temperature on the manufacturer’s website, oddly enough, not.

The mining test partially rehabilitates the oil: to the ten thousandth the run, it was able to maintain a decent viscosity (11.6 mm2 / s), and the alkaline number, although already hinting at replacement time (3.91 vyu KOH / g), still not falling out from the scope of the standard. Markers of engine wear in development at the same time scanty – that is, we can recommend changing this oil just every 10 thousand kilometers and not worry about the resource of the motor and particulate filter … but here is the pour point of the oil and remained unmeasured, so for the northern latitudes we just we don’t advise a case: Shell Helix would be the best option for them Ultra ECT C2 / C3 0W-30.

Advantages

  • Good life for medium alkaline oil
  • Excellent engine wear protection
  • Minimum sulfur and phosphorus content, low ash content
  • Viscosity Stability at High Temperatures

disadvantages

  • Uncertainty with low temperature properties

TOTAL QUARTZ INEO EFFICIENCY 0W-30

Rating: 4.7

TOTAL QUARTZ INEO EFFICIENCY 0W-30

French manufacturer usually performs well in the market medium ash diesel oils (namely, these correspond ACEA C3 quality grade required for diesel Forester): joint work with Renault, for whose diesels Total affects produces “original” oils under the Elf brand. In our case Total’s positions are also strong: at a price within 2200 rubles per 4 liter canister full of oil instructions, has a declared alkaline number of 7.5 mg KOH / g, which for medium-ash low-viscosity oil is very good. High temperature viscosity according to the manufacturer – 11.6 mm2 / s, the oil has a good margin for reducing viscosity as you get older. At a low viscosity index (180), the temperature solidification indicated acceptable – minus 45 degrees.

Let’s move on to laboratory analysis. Pour point several higher than stated (-42 degrees), the alkaline number is lower significantly: only 6.77 mg KOH / g The result is still good for this class. engine oils, but such an alkaline number when using sour fuels will definitely require lower service runs. At the same time, oil can serve much longer: the bulk of the “base” is not hydrocracking, and polyalphaolefin.

Advantages

  • Attractive price
  • High viscosity stability at high thermal loads
  • Slow alkaline number drop on quality fuel – at in this case, the oil is able to work out the normal interval normally replacements

disadvantages

  • Sensitivity to fuel quality, especially on engines with mileage
