I work at a Wally-world warehouse and they had a flatbed cart full of paint and messy oil jugs that they cant ship to the stores at a cost of a $1.00 donation to charity. I passed on the supertech jugs, but they had 5 quart jugs of pennzoil suv truck&minivan synthetic blend 10w30 SM GF-4 oil which I bought one and cleaned up nicely and was sealed when I tested it with the cap off. Is this oil any different or better then regular Pennzoil?
