Which motor oil manufacturer is better: objective rating

Choosing engine oil is a task that directly affects the life of your car’s engine. There are dozens of brands on the market with different technologies, compositions and price categories, and it is difficult to understand this diversity without expert analysis. Some manufacturers specialize in synthetic oils for modern turbo engines, others rely on semi-synthetics for budget cars, and others offer unique additives for extreme operating conditions.

In this article we will analyze 10 leading motor oil manufacturers according to key criteria: base oil composition, additive package, compliance with standards API/ACEA, real tests for wear and deposits, as well as price-quality ratio. You will find out which oil is best for city driving with frequent traffic jams, for diesel engines with particulate filter or for sports cars with high loads. And to avoid mistakes, we will reveal myths about “eternal” oils and we will analyze cases when even a premium brand can harm the engine.

Criteria for choosing an engine oil manufacturer: what to look for first

Before comparing specific brands, it is important to understand by what parameters the quality of the oil is assessed. Many car owners focus only on viscosity (5W-30, 10W-40 etc.), but this is just the tip of the iceberg. Here are the key factors that determine the reliability of a manufacturer:

• 🧪 Base oil: mineral, semi-synthetic or fully synthetic (PAO, esters, GTL). The last two options are preferable for modern engines.
• 🔬 Additive package: antioxidant, detergent, extreme pressure. For example, diesel oils with DPF contain low ash additives (Low SAPS).
• 📜 Certification: compliance with standards API SN/SP (gasoline) or API CK-4 (diesel), as well as European ACEA C2/C3.
• 🔥 Thermal-oxidative stability: how oil behaves when overheated or at long drain intervals.
• 💰 Price vs. real tests: some budget brands perform as well as premium brands in independent tests (for example, tests OCU or ADAC).

Particular attention should be paid volatility tests (according to standard NOACK). If the oil burns badly, it leads to the formation of varnish deposits on the pistons and valves. For example, oils with an indicator NOACK < 8% considered optimal for turbocharged engines.

⚠️ Attention: Some manufacturers indicate “semi-synthetic” on the label, although in fact it is mineral oil with 10-15% synthetic components. To avoid deception, check the composition in the technical sheet (TDS — Technical Data Sheet) on the brand's website.

Top 5 premium manufacturers: when the price is justified

Premium oils are 30-100% more expensive than budget analogues, but their formulas are developed for specific tasks: extending the life of turbines, protecting against LSPI (pre-detonation ignition in gasoline engines), compatibility with systems Start-Stop. Let's take a look at the segment leaders:

Brand	Technology	Key Benefits	Cons	Recommended model
Liqui Moly	Esters + PAO	High thermal stability, low waste, optimal for turbo engines	High price, fakes on the market	Molygen New Generation 5W-30
Motul	100% PAO (series 300V)	Extreme protection under high loads, used in racing cars	Overpaying for a brand is not always justified for civilian vehicles	Motul 300V Power 5W-40
Castrol	Titanium FST (titanium technology)	Reduces friction by 30%, extends timing chain life	Not all models are compatible with particulate filters	Castrol Edge 5W-30 LL
Mobil 1	Advanced Full Synthetic	Wide temperature range, low ash content	In the latest batches there is a deterioration in quality (according to reviews 2023-2026)	Mobil 1 ESP 5W-30
TotalEnergies	Quartz INEO (Low SAPS)	Ideal for diesel engines with DPF and gasoline engines with direct injection	Difficult to find in small towns	Total Quartz INEO ECS 5W-30

Stands apart Amsoil - an American brand that was the first to produce oil with a change interval 25,000 miles (40,000 km). Their products undergo stringent tests for frictional wear resistance, but there are few official distributors in Russia, and the price is steep (from 10,000 rubles for 4 liters).

Budget brands: when savings do not equal loss of quality

Expensive oil does not always mean the best. Some budget manufacturers use base oils Groups III+ (hydrocracking), which are similar in properties to synthetics, but are cheaper. The main thing is to avoid Frankenstein mixtures of unknown origin. This segment includes:

• 💎 Idemitsu - a Japanese brand with a factory in Russia. Their oil Idemitsu Zepro Touring 5W-30 shows excellent results in wear and oxidation tests, while the price is lower than that of European analogues.
• 🛢️ Lukoil Luxe - a domestic manufacturer that supplies oils to conveyors Renault and Hyundai. Series Synthetic corresponds API SP and is suitable for most foreign cars.
• 🌍 Shell Helix — despite the popularity, the quality of the latest batches (especially Helix HX8) owners of turbo engines are often dissatisfied due to increased waste.
• 🔧 ZIC is a Korean brand with a good reputation. Their ZIC X9 5W-30 often recommended for Korean and Japanese cars with mileage up to 150,000 km.

An important nuance: budget oils are often counterfeited. For example, according to RNP "Rosstandart", up to 40% oils Shell and Castrol on the Russian market - counterfeit. To avoid running into counterfeit oil, buy oil from official dealers or trusted networks (for example, "Lukoil-Auto", "TNK-Magnat").

⚠️ Attention: Oils with markings API SL or lower (for example, SJ) are absolutely not suitable for modern engines (manufactured after 2010). They do not contain additives that protect against LSPI, and can lead to destruction of the turbine or timing chain.

Specialized oils: for diesel engines, turbines and older engines

Some engines require oils with unique properties. For example:

• 🚛 For diesel engines with particulate filter (DPF): oils with low ash content (Low SAPS), for example, Total Quartz INEO ECS or Liqui Moly Top Tec 4200. Using regular oil will clog the filter and cause an error. P242F.
• 🔥 For turbocharged gasoline engines: oils with high thermal-oxidative stability, e.g. Motul Specific 913D (for Porsche) or Castrol Edge Turbo Diesel.
• ⚙️ For engines with mileage > 200,000 km: oils with high viscosity when hot (5W-40, 10W-40) and high content of detergent additives, for example, Liqui Moly Hochleistungs 10W-40.
• ❄️ For extremely low temperatures: oils with viscosity 0W-20 or 0W-30, for example, Mobil 1 Arctic (starts at -40°C).

A separate category - oils for hybrid cars. Due to frequent engine starting/stopping (mode Start-Stop) they must have improved anti-friction properties. They're in the lead here Toyota Genuine Motor Oil and Idemitsu ECO Medalist.

What happens if you pour the wrong oil into a diesel engine with DPF?

Using oil with a high ash content (for example, API CJ-4 instead of C2/C3) will quickly clog the diesel particulate filter. The engine ECU will turn on emergency mode, and the “Check DPF” error will light up on the instrument panel. In advanced cases, the filter will have to be changed (cost from 50,000 ₽).

How to recognize a fake: 5 signs of counterfeit

According to Research Institute of Standardization, up to 30% of motor oils on the Russian market are fakes. Counterfeit not only does not protect the engine, but can also cause it to break. Here's how to distinguish the original from the counterfeit:

1. Packaging: the original canister lid has an embossed brand logo, which cannot be faked without special equipment. For example, at Mobil 1 lid with "pimples" Liqui Moly - with laser engraving.
2. Price: if the oil costs 30-40% cheaper than the average market price, this is a reason to doubt. For example, the original canister Motul 8100 X-cess 5W-40 cannot cost less than 3,500 ₽ for 4 liters.
3. Dates and parties: at the bottom of the original oil canister there is a batch code and production date (for example, L2305 - May 2023). Counterfeits often lack markings or are marked with paint rather than a laser.
4. Consistency: original oil flows evenly at room temperature, without clots. If bubbles or sediment remain after shaking the canister, it is counterfeit.
5. Smell: Fake oils often smell like kerosene or have a strong chemical smell. The original smells neutral or slightly sweet (due to esters).

The most reliable way to check is to purchase from an official dealer or through trusted online platforms (for example, " Exist.ru", "AutoDoc"). You can also use originality checking services, for example, Mobil 1 Authenticity Check (just enter the code from the canister on the manufacturer’s website).

☑️ Check the oil before purchasing

Myths about motor oils: what really matters

There are many myths surrounding oils that make it difficult to make the right choice. Let's look at the most common ones:

• 🔄 "The oil needs to be changed every 10,000 km" - This is an outdated recommendation. Modern synthetic oils (API SP, ACEA C5) withstand 15,000–20,000 km under normal operating conditions. But if you drive in traffic jams or short distances, the interval should be reduced to 7,000–10,000 km.
• 🛢️ "The thicker the oil, the better" - incorrect. Oil too thick (15W-40 instead of 5W-30) worsens pumpability during cold starts and increases the load on the oil pump.
• 💎 "Synthetics are always better than semi-synthetics" - not for all engines. For example, in old engines with worn oil seals, synthetics may leak due to high fluidity. Semi-synthetics are optimal here (10W-40).
• 🌡️ "All-season oil is universal" - no. Oil 5W-30 may not be suitable for hot climates (eg Dubai), where is it better to use 5W-40 or 10W-40.

Another common myth: "Adding oil will compensate for changing it". In fact, when topping up, oxidation products and metal shavings that accumulate in the pan are not removed. You can top up only in emergency cases (for example, in case of a leak), but no more than 15% of the total volume.

💡

The most dangerous myth is “you can mix oils from different brands.” Even if the viscosity is the same, the additives may react, causing sludge or foam to form. In critical situations, mixing oils from the same manufacturer is allowed (for example, Liqui Moly 5W-30 and Liqui Moly 5W-40).

Rating of manufacturers by engine types

There is no universal "best" manufacturer - the choice depends on engine type, operating conditions and budget. We compiled the rating based on independent tests (ADAC, OCU, AAA) and reviews from car owners:

Engine type	Best Premium Brand	Best budget brand	What to Avoid
Petrol turbo engines (1.4–2.0 TSI, EcoBoost)	Liqui Moly Top Tec 4200	Idemitsu Zepro Touring	Oils without approval VW 502.00/505.00
Diesels with particulate filter (DPF)	Total Quartz INEO ECS	Lukoil Genesis Armortech	Oils with high ash content (API CJ-4 instead of C2/C3)
Old engines (mileage > 200,000 km)	Castrol Magnatec Stop-Start	ZIC X7 10W-40	Too thin oils (0W-20, 5W-20)
Hybrid cars	Toyota Genuine Motor Oil	Idemitsu ECO Medalist	Oils without approval ILSAC GF-6
Sports and tuned cars	Motul 300V Power	Liqui Moly Leichtlauf	Oils without approval Porsche A40 or BMW LL-04

For car owners with gas cylinder equipment (GBO) It is important to choose oils with increased thermal stability, since gas combustion produces a higher temperature in the chamber. Well established here Liqui Moly Gasoline Additive and Motul Specific CNG/LPG.

FAQ: Frequently asked questions about choosing engine oil

Is it possible to use an oil with a higher API class than the manufacturer recommends?

Yes, but with reservations. For example, if the instructions indicate API SNand you are pouring API SP, this is acceptable because SP - a newer standard with improved properties. However, if the manufacturer requires oil with low ash content (ACEA C2), and you will flood ACEA A3/B4, this may damage the particulate filter (if there is one).

How often should I change the oil if I only drive on the highway?

With predominantly highway driving (speed 90+ km/h, minimal downtime), the replacement interval can be increased to 15,000–20,000 km for synthetic oils (API SP, ACEA C3). However, if the engine is turbocharged, it is better to stick to an interval of 12,000–15,000 km due to increased loads on the turbine.

Which is better: mineral, semi-synthetic or synthetic oil?

Depends on the engine:

• Mineral - only for old carburetor engines (before 1990) or equipment (generators, lawn mowers).
• Semi-synthetics — optimal for budget cars with a mileage of 100,000+ km (for example, VAZ, Renault Logan).
• Synthetics - mandatory for modern turbo engines, diesel engines with DPF and vehicles with the system Start-Stop.

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

Flushing is necessary in three cases:

1. You are switching from mineral oil to synthetic oil (or vice versa).
2. The engine was filled with oil of unknown origin (for example, after purchasing a used car).
3. The engine is heavily dirty (visible by the black color of the oil after 2,000–3,000 km).

For rinsing use soft flushing oils (for example, Liqui Moly Pro-Line), and not “five-minute” ones, which can corrode the seals.

Which oil brand is the most counterfeited in Russia?

According to RosAccreditation, the leaders in the number of fakes are:

1. Shell Helix (especially the series Ultra)
2. Castrol (fake Edge and Magnatec)
3. Mobil 1 (most often falsified 5W-30)
4. ZIC (Korean brand, popular due to low price)

To minimize risks, buy oil in metal cans (they are more difficult to counterfeit) or in branded stores with a system for checking originality.
