Has anyone ever run sidewinder fuel in their engine?

As I can see, it is used for cars.

So would there be any problem using it in an aero engine ?

I woud not use it. Generally, r/c car fuel has a very low oil content.

ok

why does a car engine need a lower oil percentige ?

an airplane engine must run even cooler than a car engine?

A car engine does not need any less oil than an aero engine, but to get maximum power they are generally run with too little oil. And they commonly blow up or wear out before they start on their third gallon of fuel when used in racing.

An R/C car used just for fun is seldom run at full throttle for any length of time, and they also are constantly up and down on the throttle allowing the oil to accumulate while at lower power settings. Run this way the car engines last longer than their racing brethren too.

ahhh...ok, thanks :-)
