I was a over the road truck driver before retiring, and I drove food grade tanker trucks hauling vegetable oil.
Sometimes I would deliver to a place in Nashville, Tn that bottled it for different company brands.
The same oil would go into most all brands except wesson, crisco, and a couple others I can't remember. So when shopping for vegetable oil always buy the cheapest, it's the same as the higher price brands, Lou Anne is one that I recall...same oil.
