I use Wolf's Head Super Duty in my Chevy 454 Rv.. The reason I do is when I used to be a school bus maintenance supervisor years ago, we used this oil in all our buses and when we had to remove an intake manifold they would still be clean inside after 100,000 plus hard miles..This is what sold me on this oil.. Also drag racers used to use this oil as it was the best you could buy...
