Should the Rapid use 5w30 or 5w40?
1 Answers
The Rapid is recommended to use 5W30, preferably fully synthetic, as this oil provides comprehensive protection for the engine under high-speed and harsh conditions, making it the preferred choice. Introduction to fully synthetic oil: Fully synthetic oil refers to high-quality oil products that are 100% made from PAO (polyalphaolefin) or artificially synthesized esters, with the word "synthetic" labeled on the oil container. Classification of engine oil: Engine oil is mainly classified into mineral oil, semi-synthetic oil, and fully synthetic oil. Fully synthetic oil is the highest grade of engine oil, with the main difference between fully synthetic and semi-synthetic oils being that fully synthetic oil can be used in a wider range of temperatures and has a longer service life.
