Im hoping that the Petro Canada Ultra 94 comes out here. Gives us another option.
I guess next tank im going to give Petro 91 a shot and see what happens.
I got a guy with the exact same tune but in the states to log for me and he had next to no knock on Hess 93.
Worse case scenario I guess I have to pick a fuel and add piles of meth to get the timing I want.
