if there is a brand of oil, odds are i have dumped it into my car at sometime, everything from Caseys to Mobile 1 synthetic. i usually go for whatever is in bulk at the local gas station, i think it Trop Artic.

I am convinced that most all oils are so close in specs that your not going to kill a motor by dumping in the wrong brand. Oil companys are smarter than to sell oil that isnt up to snuff and will ruin your motor, it would cost them.
