I have 4 gallons of 15% heli cool power sitting around in my garage. I was wondering If I could put it in my os engine.

They'll work as long as u reset your needle values. Normally you'll need to set it richer than using fuel specially blended for cars to prevent overheating, but your car will appear a little slower and not as powerful. I've run heli fuel (cool power 15%, green in color) before when I'm out of car fuel, they could be OK, but not GOOD, and after 1 gallon of fuel, I found the engine wear faster than using car fuels. It's due to lubricant percentage, and that's why it's normally discouraged to run heli or plane feul in your car.

Read the section
Changing Fuel.


Most Heli fuels contain 16-20% lube. I run 20% Heli fuel and it runs cooler and with plenty of power in my Trx 3.3. Racing fuel with less lube will provide a bit more power but as I do not race anymore I am aminly interested in engine life not max. performance.

I run 30% heli fuel.....consistantly cooler engine temps than the guys running low oil content car fuel....engine life is what it's about for me!
