Quality motor oil significantly increases engine life, and also allows optimum use of precious fuel. It is noteworthy that the cost of oil is not an indicator of its quality.
Autorevue experts conducted a test of motor oils 5W-30 eight different brands to find out which engine oil is better. During testing, the oil was tested by eight identical cars under equal conditions. The result was rating of motor oils of 2014 , which we offer to your attention.
Table of contents:
- 8. ZX XQ LS 5W-30
- 7. Total Quartz 9000 5W-30( Future fuel economy)
- 6. THK Magnum Professional F
- 5. Shell Helix Ultra Extra( 5W-30)
- 4. Motul 8100Eco-energy( 5W-30)
- 3. Mobil Super FE Special Future fuel economy 5W-30
- 2. G-Energy Synth EC Secured fuel economy 5W-30
- 1. Castrol Magnatec 5W-30 A1
8. ZIC XQ LS5W-30
Oil is almost optimal in terms of price-quality ratio. ZIC provides good engine protection, low consumption for carbon monoxide, demonstrates an excellent resource of additives. Experts recommend avoiding high sulfur fuel.chemical aggressiveness is low. Oil is produced in Korea.
7. Total Quartz 9000 5W-30( Future fuel economy)
At a price of 1090 rubles per 4 liters, this oil is more expensive than Mobil, but according to the results of tests it is inferior to it in almost all parameters. If the choice still fell in the direction of Total Quartz, experts are strongly advised not to skip 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 cope well even with high-sulfur fuel.
5. Shell Helix Ultra Extra( 5W-30)
The oil has a balanced additive package, low consumption for carbon monoxide, and also does not differ aggressiveness. Unfortunately, oil is poorly compatible with high-sulfur fuel and is distinguished by a high price.
4. Motul 8100 Eco-energy( 5W-30)
Oil perfectly protects aluminum parts, slightly more cope with the protection of cast iron and steel. At a price of 420 rubles per liter, this oil became the most expensive among the rating participants. Although experts did not find outstanding characteristics that 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 mileage after oil change differed in fuel economy, with a longer run, the additive effect ends. By the way, this engine oil has the highest consumption in the rating.
2. G-Energy Synth EC Secured fuel economy 5W-30
The oil has an average consumption for fumes, a stable synthetic "base", and a record low acid number. By the way, in comparison with competitors, oil even at the end of testing saved 0.24 liters of fuel per 100 km. Experts recommend avoiding sour fuel. The reserve of G-Energy F Synth for alkaline number is small.
1. Castrol Magnatec 5W-30 A1
The best engine oil did not show a single failure according to the results of the test. 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 start the engine without problems at a frost of -27 degrees, provides a low consumption for carbon monoxide and is not subject to liquefaction.
