using the coupon, conventional grades are a purchase price of $1.39. after mail in rebate, price is .89 cents per quart. HOWEVER, if you purchase a whole case (12) you get a $5 gas card for Shell, which kinda brings the "effective" price down a bit, especially since everybody has to buy gas anyways.....BITOG has several unused oil analyses that says pennzoil is a great oil for the price, and that that wax-oil nonsense rumor is exactly that. they also have formula shell oil price of $.99 purchase, with a price of .59 after mail in rebate.
