I have a 2005 trailblazer and have been using Mobil 1 oil when I change the oil. I was wondering if it would be all right to switch to a cheaper brand of oil? Thanks
yes just don't go to cheap with it ,pennzoil isn't that much and its a really good brand of oil to run in any vehicle, i run it in almost everything i own and still don't have no problems from it,good luck and enjoy the holidays season,
Mobil 1 is not that expensive...you are probly using synthetic whis always cost more then real oil. but you can use any oil brand you want, just keep it the same grade...I mean like 15-w40 or 10-w40, just keep that part the same.
