Properly selected engine oil can serve as a guarantee of uninterrupted operation of a car engine in any climatic and road conditions.

Given that the market presents a variety of motor oils reviews ordinary motorists can be misleading.

We offer engine oil rating from the laboratory of VIAL Oil LLC and the Gubkin Russian State University of Oil and Gas, based on the results of testing synthetic oils of viscosity class 5W-40 and 5W-50.

10. ZIC XQ (Korea) - a high-quality product that can be used year-round. Physico-chemical parameters fully comply with the norms of the viscosity class. The oil showed good stability and acid number, which indicates the presence of oxidation products.

9. MOBIL Synt S (Belgium) in all respects it fits into the standards, however, experts noted that the polymer thickener showed a high degree of response.

8. SPECTROL Galax (Russia). Despite the good test results, experts noted the presence of large particles of oxidation products, as well as a fairly high rate of response of the polymer thickener. At each oil change, flushing the engine is recommended to remove possible deposits.

7. MANNOL Elite (Belgium). Of the minuses of this product, experts noted only a significant rate of response of the polymer thickener. The manufacturer claims high thermal oxidative stability of the product.

6. SELECT Lubricants Supreme (Russia) - A relatively new product on the market, however, tests show that the oil deserves the attention of consumers. During testing, this sample showed good stability.

5. AGA 027MS (Russia) demonstrated good physicochemical characteristics. Held motor oil test showed that this product is out of competition in terms of cold start. However, if the average temporal stability indicators were at an altitude, then with prolonged use of the oil its aging is noticeable.

4. TOTAL Quartz 9000 (France). The oil showed good results, experts noted the high stability of the additive package included. The period of operation of this product can be quite long.

3. CONSOL Ultima (Russia) has demonstrated high stability, as well as resistance to thermo-oxidative processes. Experts recommend oil for continuous operation with a long drain interval.

2. VALVOLINE SynPower (Netherlands). In terms of physical and chemical parameters, the product complies with established standards. Experts note that even a significant interval between oil changes is quite acceptable when using this sample.

1. SHELL Helix Ultra (Finland) — best engine oil in our ranking. Experts confidently recommend it for continuous operation. High resistance to oxidation is particularly noted.
