说来说去还是用fs稳当
其实我做的仅仅是传播一个观点:独立思考,拒绝人云亦云。
本人倾向于让各位自己了解知识并且自己做出判断。从我的角度来看,mobil 1 fs 0w40其实还是粘度太高了,我指的是暖机油温,我更希望用一只高抗磨的5w30,高温低剪值在11的样子最好,然后永远不回头。
来看一下540 rat如何回复这个类似的问题:
I don’t use that 0W40 because it is NOT the best choice. 40 weight oil at hot operating temperature is too thick to be ideal for most engines. So, why would I use it? I would not use it in your engine either, if a much more preferred 5W30 would still provide reasonable hot oil pressure in your engine.
The oil pressure “rule of thumb” recommendation for High Performance and Racing engines, is to have at least 10 psi for every 1,000 rpm. So, the thinnest high ranking oil that can meet that requirement in your engine, is what you should be looking for.
Remember, you do NOT have to use the absolute highest ranking oil on my list. Any high ranking oil will provide excellent wear protection. So, you have many choices.
You always have great questions, that can also help others as well.
Take care,

(我不使用那个0W40,因为它不是最好的选择。40重油在发动机暖机温度下粘度太厚,不适合大多数发动机。那么,我为什么要用它呢?我不会在你的发动机中使用它,如果更喜欢的5W30仍然会提供合理的机油压力在你的发动机。
针对高性能和赛车发动机的油压“经验法则”建议是每1000转每分钟至少10psi“拇指规则”。因此,能够满足发动机要求的粘度最低的高级机油是您应该寻找的。
记住,你不必在我的名单上使用绝对最高排名的油。任何高级别的油都将提供卓越的磨损保护。所以,你有很多选择。)
发动机能够合理保持油压的最低粘度的机油 抗磨排行榜高排名 方便购买,就是我们国家的机油爱好者使用指南。fs 0w40对于m274来讲,唯一的缺点就是粘度略高,不过好在还有mb229.5背书,也算是德系专用,我可以明确告诉你,bitog论坛有人提回a45amg第一件事,就是用fs 0w40替换出厂出装油。
