I'm about to do an oil change, it has been suggested that I will get far better performance using Redline 5w-40 synthetic oil rather than the recommended Mobile1. Has anyone noticed a marked difference?

Also, what is the recommendation on 0w-40 vs 5w-40 in an M275 V12 bi-turbo engine, is the only difference that 0w-40 has better coverage in colder climates?

go by the MB specs----- do the oils meet the spec\same grade comparison----if they do then the marketing HS comes into play!!

Far better performance. What does that mean, like HP increases?

I say listen to Plutoe and go by MB specs only.

Interesting stuff on oil.

I agree with following MB specs
