Just bought the last 20 quarts of Havoline synthetic 5W-30 and 10W-30 at my local Wally World. The price: $ 3 Canadian per quart (US$ 1.97). Do you guys think there is a reason for the low price? Is it because they are changing the formulation? As far as I know it is made from 100% synthetic base stocks and not hydrocracked. Any comments?
