High-quality engine oil significantly increases engine life, and also allows you to optimally consume precious fuel. It is noteworthy that the cost of oil is not an indicator of its quality.

Autoreview experts conducted a test of 5W-30 engine oils of eight different grades to find out which engine oil is better. During testing, eight identical cars were tested under the same conditions. The result was 2014 motor oil ratingwhich we bring to your attention.

8. ZIC XQ LS 5W-30

Oil is almost optimal in terms of price and quality. ZIC provides good engine protection, low waste consumption, demonstrates an excellent resource of additives. Experts recommend avoiding sour fuels, as chemical aggressiveness is low. Oil produced in Korea.

7. Total Quartz 9000 5W-30 (Future fuel economy)

At a price of 1090 rubles for 4 liters, this oil is more expensive than Mobil, but according to the test results it is inferior to it in almost all respects. If the choice nevertheless fell in the direction of Total Quartz, experts strongly advise not to miss the oil change intervals.

6. THK Magnum Professional F

Russian-made oil showed the lowest concentration of wear elements, as well as the highest alkaline number. The chemical activity of the oil allows it to perfectly cope even with high sulfur fuel.

5. Shell Helix Ultra Extra (5W-30)

The oil has a balanced additive package, low waste consumption, and is also not aggressive. Unfortunately, the oil is poorly compatible with high sulfur fuel and has a high price.

4. Motul 8100 Eco-energy (5W-30)

Oil perfectly protects aluminum parts, a little worse coping with the protection of cast iron and steel. At a price of 420 rubles per liter, this oil became the most expensive among the participants in the rating. Although outstanding characteristics, justifying the price, experts did not find.

3. Mobil Super FE Special Future fuel economy 5W-30

The oil features a balanced additive package. The first 5,000 kilometers after changing the oil were characterized by fuel economy, with a longer run the effect of the additive ends. By the way, this engine oil has the highest consumption of waste in the rating.

2. G-Energy Synth EC Secured fuel economy 5W-30

The oil has an average consumption for burning, a stable synthetic “base”, as well as a record low acid number. By the way, in comparison with competitors, oil even saved 0.24 liters of fuel per 100 km by the end of the test. Experts recommend avoiding sour fuels, as the alkaline number of G-Energy F Synth is small.

1. Castrol Magnatec 5W-30 A1

According to the test results, the best motor oil did not show a single failure. Experts note the high alkaline number of the new oil, as well as the highest acidity at the end of the test, which allows the driver to use even high sulfur fuel. Castrol allows you to easily start the engine in cold weather -27 degrees, provides low consumption for waste and is not subject to liquefaction.
