i work for walmart as a service manager in the tire lube exspress and the supertech oil (at least on the east coast) was made by pensoil quaker state but is now produced by exxon mobil i.e. the new bottles.
If you're using SuperTech oil, you're probably just as well off getting Pennzoil, Quaker State, Mobil DC, Havoline or Chevron when it's on sale for less. I got a case of Havoline for $0.69/quart (with mail-in rebate) my last visit to Checkers.
