What Fuel do You use and why?
I use Byrons 30% original. I seem to maintain a long life out of my engines, but I have been wanting to try the 40%. Any one have any input?
I have only used 40% and watched others use 40% in Nitro Dirt Latemodel oval racing. I have found it hard on the engines as well.
