"Hey, Jack! That batch of 500,000 quarts of oil, run 400,000 into our bottles and 100,000 into the Thifty's."
I buy whatever's on sale. Never had an engine failure yet due to an "inferior" oil in 40+ years of owning/maintaining vehicles.

I just do not trust it. It is the or other ?????? that concerns me. A complete unknown. I assume then in 40 years you have used quite a bit of Thrifty oil as it is the cheapest, and no problems. Or what is cheaper than Thrifty if I might ask?
