I would also check your front & rear main seals as well.

Ok so i have read all of your posts and appreciate all the helpful advie given by all....so i guess i have 2 choices really: 1) would be to go out and pull all of my spark plugs and check for black soot on them (i recently replaced all my spark plugs last month so it would be easy to tell if they were coated); or 2) i could just start using the regular 20w-50 and monitor it and see how that goes for me. i personally am leaning more towards option number 2, as i hate messing with the plugs especially since the wire tends to slip off them while im driving....and i have such a horrible idle that i know a plug wire has come loose. i dont have that problem now, just when i first changed the plugs, dont know what it couldve been, but all better now. so i will just try the 20w-50, monitor it and if i have excessive consumption still, then ill pull the plugs and check.
