When my 190 is back from the shop......
I'll go to an MB dealer and find an owners manual. A repair manual would be great too, but I think I can get one from Schucks.com
I saw the debates about regular oil vs. synthetic oil- totally confusing. I think I'll pick one and see how it works; but I still don't understand all the various weights, I'm more concerned with using the correct type of oil vs. using the correct brand of oil.
