Motul 8100 is what I am using.

 

Mobil 1 5w-20. I have always used Mobil 1 since 1988. My father told me it was the best money could buy, and I used to really dig those commercials with the guy in the fire suit in a blast furnace broiling Mobil 1 and another name brand conventional oil in pan and then showing the results. Mobil 1 always looked like new. I don't know it was a very effective image. Not the exact commercial I was talking about, but look at commercial here. BTW recognize Gene Hackman in United Commercial.
