What they're Saying about PennGrade

PennGrade 1 Customer

I was told by a number of trusted experts that PennGrade 1 is the best oil for my high pressure classic engine. Even in 100 degree weather I don't think my oil pressure ever drops below 55, and that is five pounds more than my engine's normal pressure range.

I have seen specific drops in temperature on my racecar as well as a more balanced pressure reading in the lower ranges under high temperature that I did not get with other racing / high performance oils.
