Race Fuel Octane/Performance Question

[njk53]

No, we have never tried the Sunoco 112. We figured the higher the octane the worse the combustion efficiency would get with the higher octane. We bought 2 pails of Sunoco 260 GTX and if weather permits we are going to Milan for the Great Lakes Stock/Superstock event on Sunday. I will let you know how it goes. Also, we can try Sunoco 112 and compare it to the 260 GTX. Thanks for the input.
