High-quality engine oil significantly extends the engine's life, and also allows you to optimally use precious fuel. It is noteworthy that the cost of oil is not an indicator of its quality.
Experts from AutoREVUE tested 8 different brands of 5W-30 engine oils to find out which engine oil is better. In the process of testing, the oil was tested by eight identical vehicles under equal conditions. The result was rating of motor oils 2014, which we bring to your attention.
8.ZIC XQ LS 5W-30
The oil is almost optimal in terms of price-quality ratio. ZIC provides good engine protection, low waste consumption, and demonstrates an excellent additive resource. Experts recommend avoiding high-sulfur fuels as chemical aggressiveness is low. Oil produced in Korea.
7. Total Quartz 9000 5W-30 (Future fuel economy)
At a price of 1,090 rubles for 4 liters, this oil is more expensive than Mobil, but according to test results it is inferior to it in almost all respects. If the choice nevertheless fell towards Total Quartz, experts strongly advise not to skip oil change intervals.
6. THK Magnum Professional F
Russian-made oil showed the lowest concentration of wear elements, as well as the highest base number. The chemical activity of the oil allows it to cope well even with high-sulfur fuels.
5. Shell Helix Ultra Extra (5W-30)
The oil has a balanced additive package, low waste consumption, and also does not differ in aggressiveness. Unfortunately, the oil is poorly compatible with sour fuels and is expensive.
4. Motul 8100 Eco-energy (5W-30)
The oil perfectly protects aluminum parts, while coping with the protection of cast iron and steel a little worse. With a price of 420 rubles per liter, this oil became the most expensive among the rating participants. Although the experts did not find outstanding characteristics to justify the price.
3. Mobil Super FE Special Future fuel economy 5W-30
The oil is distinguished by a balanced additive package. The first 5,000 km of run after oil change were distinguished by fuel economy; with a longer run, the effect of the additive ends. By the way, this engine oil has the highest waste consumption in the rating.
2. G-Energy Synth EC Secured fuel economy 5W-30
The oil has an average waste consumption, a stable synthetic base, and a record low acid number. By the way, in comparison with competitors, even by the end of the tests, the oil saved 0.24 liters of fuel per 100 km. Experts recommend avoiding high-sulfur fuels as the base number of G-Energy F Synth is small.
1. Castrol Magnatec 5W-30 A1
The best engine oil in the test did not fail. Experts note the new oil has a high base number, 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 start the engine without problems in freezing temperatures of -27 degrees, provides low waste consumption and is not subject to liquefaction.
