Last year at Autolite Nationals the Vavoline booth was selling the not street legal oil for 4.00 a Qt. I'm swooping on some of that this year if they are out there again.
THAT is a deal. I think Jegs sells it for 8 buckes a quart. The last time I bought it I got it from Napa Auto Parts but they had to order it from their Nevada warehouse. Almost worth going to the nationals just for the oil. LOL
