For all around performance in a race engine with 11:1 or higher compression, it's hard to beat a top quality 110. The Renegade Pro 110 has the highest Motor Octane numbers. For Crate engines, the Renegade Rat Man Crate Elite is the best choice.
For engines that use only pump gas, stick with Shell and use their highest rated gasoline.
