Scored 11 quarts at Advance Auto for $0.05/qt. Not a misprint. A nickel a quart on clearance. No starburst symbol, no 'S' or 'C' rating of any kind. A couple of direct quotes from the back on the quart container: "Mobil 1 Racing 0W-30 is especially recommended for supercharged, turbo charged, muscle cars, and amateur race cars." "Mobil 1 is proven to outperform conventional oils [DUH!], and is used by Penske Racing in all of their race cars." Talk to me, BITOGers. Can I use this in my "full race" mini-van, Prizm, and Sable safely?
