Yes i have 5w30 in the car now. i think i put in 6 quarts i might have to add an extra quart! im thinking about switching to AMSOIL! i know a guy who used to work for them and he has used it on his car for the last 200k miles! only changed the oil like 4 times!
anyway i want to get the preventative stuff first. where should i research these problems?
thanks again
