hi everyone, i know that there is a lot of topics on race fuel, but ..... basically I've been have given 40 gallons of 104 octane race fuel. I need to know if its perfectly safe to run in my 2013 kxf250. no engine mods except a high comp piston. ive been told that over a short period of time it will blow a hole in the top of my piston !!! ( obviously i don't want that to happen. ) is it safe to run mixed or would i be better of selling it to someone who really needs it. if its safe to run then i will run it mixed with pump gas but i dont want to have to rebuild my motor every month. cheers guys.
