"If that's true, tell me, what's the difference between a bottle of Mobil 1 from O'Reily's and one from Autozone or Advance?"

Yeah, if it's a national brand no. I sure did see a lot of weird cheap off brands I had never seen before. Kinda like the stuff you see on the "car parts" aisle at a bad convenience store...I guess I also was pissed off when the parts guy said "oh yeah, dextron III is the same as Dextron IV or V". Wrong!

I guess you just go where it's good for you and hope it lasts!
