Bought a 2004 Silverado Z71 with the 4.8 and 118k miles on it last year. I've changed the oil and filter three since then, and only put 1k on each oil change, just because the oil change history is unknown to me. First time was Valvoline synpower (had on hand), next time was M1 5w-30 again had on hand. Third time was ST HM syn 5w-30 because at some point it developed seeping from the pan. Not sure if that always was there or started after I got the truck.
Does anybody have any recommendations on oil that might help with the seeping? Maybe the new formulation of Valvoline advanced max life? I don't really know how picky these engines are as far as brands or even weight, other than if it's not driven for a week or so the lifters make noise at startup for a minute or two.
