Can any of you please tell me what kind of oil a 1991 blazer takes?
LOL I know I know you must think i'm some kind of retard about cars lol (cars i'm okay but I just want to make double sure...) Thanks for your help! If you have a computer question feel free to ask lol (I'm a nerd but not dungeons and dragons/magic nerdy *shudder*)
These engines live just fine on any name brand conventional (non-synthetic) oil. Given where you live and the age of your engine I would recommend 5W30 weight, perhaps a 'high mileage' type oil.
