If you decide to get the Castrol GTX HM, don't forget about the mail in rebate if you buy 5 quarts.

$5 rebate on 5 quarts....two rebate limit per household. Make sure that if you buy 2 Jugs, get a separate receipt for each jug and mail in each receipt with the rebate form in a separate envelope.
So with the $5 rebate on a jug of Castrol High Mileage, it will put it in the Quaker State Conventional ballpark. $18.50 - $5.00 = $13.50
