What kind of engine oil should be used for Toyota Reiz V6?
2 Answers
Toyota Reiz V6 recommends using fully synthetic engine oil. The benefits of using fully synthetic engine oil: 1. Low evaporation loss: Synthetic oil is generally a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, reduce exhaust emissions, and extend the service life of the catalytic converter. In addition, compared with traditional mineral oil-type engine oil, synthetic engine oil also has excellent chemical stability, good radiation resistance, high oil film strength, and less foam. Therefore, high-end cars generally choose synthetic engine oil. 2. Strong high-temperature oxidation resistance: The thermal oxidation stability of synthetic oil is much better than that of mineral oil-type engine oil, which means the tendency to produce acid and sludge due to oxidation is small. Under various harsh operating conditions, it can provide appropriate lubrication and effective protection for the engine, thus having a longer service life and ensuring the performance stability of the engine oil during long-term use. In the same working environment, synthetic oil has a much longer service life than mineral oil, so although the cost is higher, after comparing the number of oil changes, it is not much higher than mineral oil.
My car is a Toyota Reiz V6, and over three years of using engine oil has taught me that the first choice should always be the 5W-30 synthetic oil recommended in the manual. The manual is the authoritative guide, specifying based on the engine design to avoid issues like friction or overheating from using the wrong oil. I make it a habit to change the oil every 8,000 kilometers, especially since city driving tends to cause carbon buildup, which helps extend the engine's lifespan. I've used brands like Castrol and the original manufacturer's oil, both of which work well. Regular maintenance combined with quality oil ensures quick starts, better fuel efficiency, and no strange noises even on long trips. Avoid switching to higher viscosity oils like 10W-40 without reason, as it may increase fuel consumption without clear benefits for the engine. Remember, checking the oil level is simple—just wait 10 minutes after parking and check the dipstick; clear, bright color means it's good to go.
