What kind of engine oil is best for Toyota Vios?
1 Answers
In winter or areas with consistently low temperatures, Toyota Vios should use 0W-20 grade engine oil; in summer or areas with consistently high temperatures, 5W-30 grade engine oil is more suitable. There are several types of engine oil: conventional mineral oil, semi-synthetic oil, and full-synthetic oil. The functions of engine oil are as follows: 1. Separate the surfaces of relatively sliding parts to reduce wear. 2. Bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine. 3. Circulate carbon deposits, sludge, and wear particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.
