Ok, thanks very much guys, I see that according to the reactions I have received so far that it isn't an issue to use a modern multigrade instead of the good 'ol SAE30 single grade. To get some of the viscosity of an SAE30 oil I might be better of then with a 20W50 then a 10W40. Now I have to look if I can find an oil of that grade here in the Netherlands! I might be lucky, cause I knew at least one shop that sells SAE30 so maybe the owner will also have 20W50 in stock :) Robert Op Vr, 16 juni, 2006 12:14 am, schreef Klebert L.
