Re: what brand oil does everyone use?
I use Royal Purple 5w30 in my 4.7 WK. Napa Gold Filters because i got 7 for free new from a friend. 6000 mile interval. Supposedly RP can go for 15k but i drive alot and kinda hard so i like to change it every 6k. and it usually gets me out of an oil change during the winter if i time it right but right now i am out of sync and need to do an oil change in 1000 miles.
