you would need to check the exact composition of the fuel you were buying.

Most heli pilots use fuels mixed with synthetic oils rather than the more traditional castor oil based glo-fuel.

The demands on the fuel will be different for a car engine which will be speeding up and slowing down all the time and a heli that once up to speed stays at about the same revs for the whole flight.

I'm pretty sure yellowtang mixes his own fuel by adding heli oil to some other kind of fuel, but i may have confused him with someone else
