Toyota的Alphard,V6 3.5 2GR-FKS应该用哪款机油呢?说明书是日本的,推荐用0W20。我觉得这个油可能更适合 ...
如果手册上只推荐了单一个确切的viscosity 0W20,且里程不超10万公里,那就用它,0W-的油用在热天里冷启时肯定更没有问题。如果推荐的是一个range,我觉得夏天时可以用用0W30、5W30,-30的油在operating temperature更稠一些,油膜强度理论上更强一些,但也不能无限度地用更高标号,否则机油压力太大,此外也反而增加零部件运转的阻力。
或者,就以2GR-FKS为关键词在各个机油品牌的lube-guide/lube match里查找试试看?比如Valvoline的:
https://www.valvoline.com/en-australia/lube-guide
点它的Retail版,能搜到装备了这款发动机的6款车型。
但是我发现同一款发动机在不同的车型上,机油厂的首推用油却不一定一致……但是它的推荐肯定不是瞎推荐,基本上各大机油品牌都有这样的oil selector,都是根据来自主机厂的数据进行推荐的,比如Valvoline的:

比如Penrite的:

如果想用castrol、shell、nulon、mobil 1,就google品牌名+oil guide,也就搜到了。 |
