if it says WPP on bottom of jug its made by Warren, as the supertech is here. which is basically the same as aap, az & others house brand. I've used before with no problems.
however, I just bought 2 jugs of PP at Kmart on sale for $24.49 & used at coupon had for 15% off on purchase over $100, as bought other stuff needed. so actually only paid $20.82 about. so I feel there are many better deals to be had, although I haven't seen the $1 & $3 quarts everyone talking about. but if don't want to shop around ST is easy way to save $ and won't hurt, I'd even go to 5k miles for warentlqtrwow
