I bought a barrel of VP110 today. Does anyone know the differences performance wise between Turbo Blue 110, Sunoco standard 110 and VP110. I was told to check the specific gravity. The Turbo Blue was .743 the Sunoco was .729 and the VP was .705. I was told the higher the specific gravity the richer it would run using the same jet so I went with the VP with the lowest specific gravity thinking it would be more efficient. I am sure it will work fine. Does anyone have experience with switching between brands (with different specific gravity and same octane) and jetting requirements changing?
