I did oil changes on my E90 myself. I used LM 5w-40. So, I am planning on changing the oil on the G30 every 6 months of 5k miles.
I know BMW recommends LL-14 FE+ rated oil for better fuel economy on the newer BMWs. Can I run LM 5w-40 in the G30 or would that be too thick? I'm not going to be tracking it. Just driving to and from work.
Would running LL-01 void the 2 years of warranty I've got left?
0w-20 seems to thin to be running in a BMW IMO
