after changing from Q8 F1 10W50 to Motul I have noisy lifters on startup and sometimes later when oil is hot...
so,is it true that LET doesn't like ester oils? (I used before PAO full synt oils)
On Q8 stuff there was no lifter noise not even on cold start...
I had new set of lifters on overhaul (after some 10k kms)

My let was quiet until I made the mistake of putting 15W50 in it :rolleyes:
Never not tapped when cold in the 2 years since changing it.
5W40 is best choice, all things considered - Fully Synth obviously.
