Okay I need to change my oil, this will be the first time that I will be doing this myself. My 041K has 4500 miles on it and the oils hase been changed once for the first service by the dealer and again 1200miles later by a mechanic that my race buddies use. He put Amsoil synth 10w40. I now have been told by another dealer that I should not use synthetic because of the wet clutch and the molly in the oil will cause it to slip. :headscrat Is this a factor? Which oil should I use? I know there are alot of brands but what are the top choices. Has anyone ever heard of this. Any knowledgeable advise is appreciated. :hmmm: :hmmm: :hmmm:
