LOL ok just to let everyone know most airplane and heli fuel(where I live anyway) its at LEAST 50% and its really not needed to run in a car engine. Car engines have more torque then airplane and heli engines. Airplane and heli engines are built with lasting HP because they run at high speed all the time and thats why they add more oil and nitro then car fuel. The reason the airplane and heli engines last longer is also the use of rings(80% of all AP and heli engines have them)and high oil content. You could find if possible use a 15-20% heli or AP fuel and run in a car engine and should somewhat lengthen the lifespan of the engine. High oil content will help with lean jet settings because of the amount in the mixture but wont protect in high temps(piston gets too big in the sleve, oil cant get in between). Air filter failuse WILL score the sleve to the point of compression leaks(had this happen to a VX-18 in my basher buggy, still runs after this but not for long )and will also cause bearing failures. Also the prop and rotors help keep the engine cool while running because of the high nitro content(more % of nitro, the hotter it burns).

Hope this helps you
