Good morning, let me speak again, last topic was:https://www.motor-talk.de/…/…obleme-e63-650i-cause-t6486678.html Thanks to a competent small workshop, I was able to solve for 200€, the ground line was “clogged” it was cleaned and since then it does not run any problems!!! Now I wanted to ask what you recommend for an oil? I drive LEIDER 80% short distance, I know for a V8, but I absolutely wanted it…. e only 4km to work, no possibility with bike! Otherwise a lot of city, but bang it even if it is warm! I thought about 5w50 of Mobil1? Or rather 10w60? What do you think? A little troublesome problem I have, sometimes the speed varies, whether I drive or give gas, or when I am idle, the speed goes up and down by about 30-40 revolutions, is something annoying, but a real problem not or? Error memory Anyway, it doesn’t consume oil either. Well, the oil temperature also rises to over 100 degrees without having to bang it on the AB, sometimes already after 20-30 minutes in normal traffic, if I really stick it then the oil also likes to go to just under 120 degrees? Thank you PS: Before you complain that I “suck” such a beautiful old school engine through short distance, I plan 2x an oil change every year.
