I just came back from a trip to Walmart to buy ATF4 (ouch $9.50 a quart)... I noticed they had Chevron Supreme again, but the price is up to $19 a jug. The synthetic SuperTech seems like a better deal these days.
The relationship between Chevron Supreme and Havoline is sorta like what Quakerstate is to Pennzoil. Made by the same company and 1 cost more than the other as if it’s a superior product. It may be but we really don’t know
