Currently waiting on my new engine from RPG. Looking for experience/opinions with breaking in high compression builds and which fuel to use. I've read/heard from the engine builder not to use E85 for break in as it can "wash out" the cylinders, less lubricative than gasoline and you want a decent amount of heat and obviously e85 burns cooler. Both Lund and RPG have said 93 for break in should be no issue. And I trust them, just cant help but to be a little timid because of what I read online regarding the need for high octane for high compression engines. Will 93 be fine? Full build is below.
