Thanks for the help with the oil selection. I think that is my next try before tearing into the engine. I have been putting in some crazy hours at work so haven't had time to buy the oil. Hopefully I can do that before next week. I at least want to get the LUCAS treatment out of my oil pan. Thanks again for your replies and I will respond next week when I try the Rotella. On another note a sales guy at one of the auto parts chain gave me an additive/cleaner to add to the oil. I think it is CD2. Do you have any recommendations or experience with this product? Cheers
