Which oil to buy for your car: a complete selection guide in

Choosing engine oil is one of the most important tasks for a car owner. Not only the service life of the engine, but also fuel consumption, acceleration dynamics, and in some cases, even the possibility of maintaining the warranty, depend on the correct decision. However, the range of modern oils is so wide (synthetic, semi-synthetic, mineral water, hydrocracking, esters) that it is almost impossible to understand it without preparation.

In this article we will not just list brands and viscosity grades, but give practical recommendations taking into account climate, vehicle mileage and engine type. You'll find out why Mobil 1 it could be worse Lukoil Luxe for your car, how to decipher the markings 5W-30 API SN/CF, and why saving on oil costs turbine repair or engine capital. And for those who have already decided on the type, we will give current rating of oils for 2026 based on the results of independent tests.

Synthetic, semi-synthetic or mineral water: which is better for your engine?

The main separation of oils occurs by basic basis. Performance properties depend on it: oxidation resistance, temperature range, replacement intervals. Let's figure out which oil is suitable for your case.

Mineral oils (mineral water) today are almost never used in passenger cars - their niche is old carburetor engines (until the 1990s) or large-volume equipment (trucks, tractors). They are cheap, but quickly lose their properties: after 5–7 thousand km they require replacement. If you have VAZ-2106 or UAZ "Loaf" - mineral water 15W-40 may be justified. For everything else, no.

Semi-synthetic oils - the gold standard for most budget foreign cars and domestic cars (for example, Lada Vesta, Renault Logan, Hyundai Solaris). They are cheaper than synthetics, but superior to mineral water in stability. The best choice if:

• 🚗 Your car is over 10 years old or has a mileage of >150 thousand km (semi-synthetics are softer for worn out oil seals).
• 💰 Budget is limited, but you don't want to risk the engine.
• 🌡️ The climate is moderate (from −20°C to +30°C).

Synthetic oils (including hydrocracking and esters) is the best choice for modern turbocharged, diesel and high-performance engines. They maintain viscosity longer, provide better wear protection and save fuel. Required for:

• 🔥 Car with a turbine (for example, Volkswagen 1.4 TSI, BMW N20).
• ❄️ Operation in frosts below −25°C or heat above +35°C.
• 🏁 Sports cars and engines with direct injection (Mazda Skyactiv, Toyota D-4S).

Decoding the markings: what do SAE, API and ACEA mean?

On the oil canister you will see a set of letters and numbers like 5W-30 API SN/CF ACEA A5/B5. This is not a random set - this is the key to oil compatibility with your engine. Let's figure out what these designations mean.

SAE (viscosity) - the most noticeable parameter. It shows how the oil behaves at different temperatures. For example, 5W-30 deciphered like this:

• 5W — winter viscosity (the lower the number, the better the oil works in cold weather). "W" means Winter (winter).
• 30 — summer viscosity (the higher the number, the thicker the oil when heated).

Optimal for Russia all-season oils with range 0W-40 (for severe frosts) or 5W-30/5W-40 (universal option). If you live in Sochi, you can take 10W-40; if in Yakutia - only 0W-20 or 0W-30.

API (American standard) divides oils into categories for gasoline (S...) and diesel (C...) engines. The further the second letter is from the beginning of the alphabet, the more modern the standard:

• SN - for gasoline engines after 2010.
• SP - the newest standard (2020), mandatory for Toyota GR86, Honda Civic 2023.
• CF - for diesel engines with a turbine (for example, Mercedes OM617).

ACEA (European standard) stricter than API and takes into account environmental standards. For example:

• A5/B5 — energy-saving oils for gasoline/diesel (suitable for Ford EcoBoost).
• C2/C3 - oils with low sulfur and phosphorus content for catalysts and particulate filters (mandatory for Volkswagen TDI, BMW with DPF).

What happens if you fill in oil of the wrong standard?

If you fill in oil with the wrong API/ACEA, the consequences can be fatal:

- For turbodiesel with diesel particulate filter (DPF) oil without approval C3 the filter clogs within 10–15 thousand km (repair from 50 thousand rubles).

- In modern gasoline engines (for example, Mazda Skyactiv-G) oil without SN or SP leads to sludge formation and ring sticking.

- In old cars (before 2000), the oil is too “advanced” (for example, SP) can cause leaks through worn oil seals due to high cleaning properties.

Table: what oil to fill by car make and model

Manufacturers indicate recommended oils in the service book, but often this data is lost or outdated. Below is the current table for popular brands (data for 2026). If your model is not available, focus on the year of manufacture and engine type.

Make/Model	Year of manufacture	Engine type	Recommended oil	Tolerances
Lada Vesta, Granta, XRAY	2015–2026	Gasoline 1.6 (8/16 cl)	5W-30 or 5W-40 semi-synthetic	API SN, ACEA A5/B5
Toyota Corolla (E210)	2019–2026	Gasoline 1.6/2.0, hybrid	0W-16 or 0W-20 synthetics	API SP, ILSAC GF-6A
Volkswagen Polo, Skoda Rapid	2017–2026	Petrol 1.6 MPI, diesel 1.6 TDI	5W-30 or 5W-40	VW 502.00/505.00 (petrol/diesel)
Hyundai Solaris, Kia Rio	2017–2026	Gasoline 1.4/1.6	5W-20 or 5W-30	API SP, ILSAC GF-5/6
BMW 3 Series (G20)	2019–2026	Gasoline 2.0 turbo, diesel 2.0	0W-30 or 5W-30 LongLife	BMW LL-04 (diesel), LL-17 FE+ (petrol)

Important! For cars with mileage >200 thousand km or age >15 years it's impossible use low viscosity oils (0W-20, 5W-20). They will not provide sufficient protection for worn parts. Optimal choice - 5W-40 or 10W-40 with a high content of additives.

5 mistakes when choosing oil that kill your engine

Even experienced car owners sometimes make fatal mistakes. Here are the most common of them - and what they threaten.

⚠️ Attention: If you have filled in oil with an inappropriate viscosity (for example, 10W-40 instead of 5W-30), don't panic. A one-time replacement will not cause damage, but at the next maintenance, return to the recommended standard. An exception is oils with incorrect tolerances (for example, without C3 for diesel with DPF). Here the consequences can be immediate.

Mistake 1: Saving on cheap “synthetics”

Oils with the inscription "100% Synthetic" for 800 rubles. for 4 liters is a scam. True synthetics (PAO or esters) cannot be cheap. At best, they will sell you hydrocracking (improved mineral water); at worst, they will sell you a fake. Consequences: oil waste, ring sticking, turbine wear.

Mistake 2: Ignoring manufacturer's tolerances

For example, in Volkswagen Passat B8 with motor 2.0 TDI Approved oil required VW 507.00. If you fill it with regular 5W-40 API CF, the particulate filter will fail after 20–30 thousand km. Repair cost: from 80 thousand rubles.

Mistake 3: Changing the oil less frequently than required

Manufacturers often indicate an interval of 15–20 thousand km, but this is for ideal conditions (Europe, high-quality fuel). In Russia, oil ages faster due to:

• 🛣️ Bad roads (dust, dirt gets into the crankcase).
• ⛽ Low quality gasoline (accelerates oil oxidation).
• 🚗 Frequent trips over short distances (the oil does not warm up to operating temperature).

Recommendation: Change the oil every 7-10 thousand km or once a year (whichever comes first).

Mistake 4: Mixing different oils

If you had to add another brand of oil, use a product with the same basis and tolerances. For example, you can mix Mobil 1 5W-30 SP and Liqui Moly Top Tec 5W-30 SP, but you can't interfere 5W-40 and 0W-20. Consequences: sedimentation, clogging of oil channels.

Mistake 5: Neglecting the oil filter

A cheap filter (for example, no-name for 150 rubles) does not retain wear particles, and they circulate throughout the system. Result: accelerated wear of liners and crankshaft. Conclusion: Take filters from trusted brands (Mann, Bosch, Framm) and change them at every oil change.

I checked the tolerances in the service book

Selected viscosity according to climate (for example, 0W-30 for frost)

How to check oil authenticity: 3 ways

The auto chemical market is flooded with fakes. According to RNP "Rosstandart", up to 30% of motor oils in Russia are counterfeit. Here's how to distinguish the original from the counterfeit.

Method 1: Checking the canister

The original packaging has:

• 🏷️ Hologram with a changing pattern (on canisters Mobil, Castrol).
• 🔢 Serial number under the cover (can be checked on the manufacturer’s website).
• 🖨️ Clear font without blurring (counterfeits often have crooked letters).

Method 2: Viscosity Test

Drop oil onto cold metal (such as a hood) and tilt the surface:

• ❄️ Original 0W-20 drains almost instantly even at −10°C.
• ⚠️ Fake 5W-30 it will be thick like honey.

Method 3: Laboratory analysis

If in doubt, send the sample to a laboratory (e.g. Oil Club or Modenji). The cost of the analysis is 1,500–2,500 rubles, but it is cheaper than engine repair. The report will check:

• 🧪 Compliance with the declared viscosity (according to SAE).
• 🔬 Availability of additives (fakes often do not have them).
• 🚯 Impurities (for example, glycol from antifreeze - a sign of illegal production).

⚠️ Attention: It's not just premium brands that are counterfeited (Mobil, Shell), but also budget (Lukoil, Rosneft). Buy oil only from authorized dealers or trusted stores (for example, Exist.ru, AutoDoc). Avoid spontaneous markets and “promotional” offers on social networks.

FAQ: Frequently asked questions about choosing oil

Is it possible to fill in oil with a higher viscosity than recommended (for example, 10W-40 instead of 5W-30)?

If the engine is in good condition and does not have high mileage - no. Thicker oil is pumped worse through the system during a cold start, which leads to oil starvation. Exception: old engines (mileage >200 thousand km), where increased clearances require more viscous oil for protection.

What is better: synthetic or semi-synthetic for a car with a mileage of 100 thousand km?

Depends on the engine condition:

• If the engine does not “eat” oil and does not smoke, you can stay on synthetics (for example, 5W-30).
• If there is oil loss (>1 liter per 10 thousand km) or leaks, go to semi-synthetics 5W-40 or 10W-40 with increased viscosity.

Do I need to flush the engine when changing the oil?

Flushing is only necessary in three cases:

1. You are switching from mineral water to synthetic water (or vice versa).
2. Coolant or fuel has gotten into the old oil.
3. The car was bought secondhand, and you don’t know what was filled in previously.

In all other cases, it is enough to drain the old oil and replace the filter. For rinsing use special compounds (Liqui Moly Pro-Line) or oil of the same brand that you will fill.

What oil should I put into a diesel engine with a diesel particulate filter (DPF)?

Required oil with approval C2, C3 or C4 according to ACEA (for example, Shell Helix Ultra ECT C3, Total Quartz INEO ECS). These oils have low sulfur, phosphorus and sulfated ash (low SAPS) content, which prevents filter clogging. Using regular diesel oil (e.g. API CF) will lead to DPF failure in 1–2 years.

Is it worth buying oil in bulk? Are the savings worth it?

No, it's not worth it. Oil on tap often:

• Diluted with cheap mineral water.
• Stored in dirty barrels (risk of water or metal shavings).
• Does not have certificates (you will not be able to make a claim if it breaks).

Savings of 200–300 rubles. doesn't justify the risks. The exception is verified service stations that purchase oil in large cans (20–60 l) from official suppliers and can provide documents.
