Ummm… 4 quarts at $45 means 6 quarts costs $67.50… but you probably bought 3 jugs to get 12 quarts, so that’s $135.Not everyone is into Amsoil. The point I was trying to make is the relative cost. As far as I know Super car is almost $60 a case of 6 quarts. In comparison Signature is $45 a gallon. That small difference made my go Signature for my L84. However nothing wrong with Super car.
Either oil is really good, but I’m pretty sure your math is suspect.
