'98 S10 in profile is at girlfriends work (Chevrolet dealer) getting valve cover gaskets, oil pan gasket, rear main seal, & front cover with front crank seal. I asked her what kind of oil and filter do you think will go in it? She replied "I don't know, what do you want to go in it." I stopped by Wally World on the way home and got a 5 qt. jug of M1 HM 10W30, and an M1-201 oil filter and told her this is what's going in it. This should carry the truck to the 200K mile mark.
