Since the ET4 takes a liter or a little bit more, a quart is not enough so I added a little bit of Motul 7100 15w-50 to the Mobil 1 5w-40. I know, that was cheap of me, but I hate having an almost full quart that won't be used. Is this OK?
Motul 7100 15w-50 is Jaso MA rated so you will have lost 1/2 a teaspoon of friction additives. You don't have a wet clutch so you may use Jaso MB rated oil next time.
