mb229.52,pdf文件上明确写明严禁使用在西欧地区以外的汽油机。很早以前我给你回复过,这个esp 0w30不适合中国汽油。
The ESP version (5W30) cannot sustain 5K in DI engines.
LZ study found that with Low-SAPS oils carbon build up on exhaust valves (yes I know what I said) is 167% lower then with High-SAPS oil.
You misunderstood me when it comes to gas. In Europe due to ULSG you can use with no problems Low-SAPS oil which mitigates issue to certain extent (well S4 or 3.2V6 not really). I tried M1 5W30 ESP here and did UOA after 3K. TBN was below 2.
美国一个老外用esp 5w30 三千英里uoa显示tbn低于2,可以说基本失效了。(这里说一句,如果你一定要用esp系列,建议esp 5w30,在抗磨排行榜上有相当高的排名,esp 0w30按照排行榜的规律,很难和5w的油膜强度来抗衡。)

总体而言,你硬是要用c3,只能大幅度缩减换油里程。所以本人的推荐依然是宝马和玛莎拉蒂惯用的shell ultra 5w30 SL,或者粘度略高一线的美孚欧洲车换代配方fs 0w40。
