for car above 100k you should use 10w-30, for high rev engine usually is -40, usually motorcycle is at 10w-40 as normal 10w-50 is for those who likes to rev at 10k rpm and above. most normal cars usually go at 2k-4k rpm, so stick to your manufacturers recommendation. Those that like to rev at 6k till max depending on high performance engine every other weekend, better go with 5w-40. At high rpm 5w-30 won't offer any protection

只要定期换或者早换都对引擎比较好

API/ACEA grade is very important, more important that 5w30 40 50, many people ignore this.

Mr Low, on the same viscosity like 5w30, it has fully and semi synthetic. May I know the differece between these two?
我上次从5w30换LM AA tec 0w20过后车马上感觉没力,过了一段时间好像又比较顺。可能之前用5w30royal purple hps的性能比较好。下次不换粘度了,保持0w20就好。

你的车原厂要30的不能换20。密封性不够漏气。而且很可能拉缸了

不同的引擎间隙设计都不一样你用太薄的机油还不是特级的完全保护密封不到引擎。

User manual guide is for save fuel, not engine protection for long term. City wise usage good to use 5W-30, but highway or long distance usage is better for 5W-40 as thicker oil can hold longer in hot engine for better protection.
