_________________For $20.00+ a Qt I can't say I will switch to Amsoil. From my previous use of it I did not think it did that well. Even if you consider it can probably out perform Pennzoil in long distance racing you are paying nearly 4x the amount.
______________some amsoil on ebay came up with 0w-20 for $7.75. No clue if every weight they sell is different in price. I put like 5 quarts in the shopping cart and shipping was like $9 on the 5 quarts. Not sure if other people are charging 20 bucks offline.

_______________We have a shop that sells Amsoil near me. I am sure you could probably find I cheaper from a local certified dealer but I never really asked for the price of the oil.
