picked up 17 qts of 0w40 pennzoil ultra today and a bunch of the castor yesterday. went to 2 AZ's near me, and all of the castrol was back @ regular price. they had kendall 10w40 in stock for $1 as well as Havoline Dino for $1. Pennzoil will go into the BMW. Now waiting to see if the kendall 10w30 comes in or not
