Gasoline will turn a nitro RC motor into a little grenade.

The reason you CANNOT run gasoline in a nitro motor is because gasoline does not need as much compression to burn and is more explosive than nitro fuel. If you pour a spot of gasoline on a concrete surface and light it, it burns up very fast. Do the same with nitro fuel and it will burn very slowly. Nitro fuel consists of 3 components, Methanol (which is the main fuel base), Nitro methane (which adds that little extra boost needed to provide sufficient power in a smaller motor), and castor and synthetic blended oils for lubrication. Methanol burns slower than gasoline but the burn is accelerated by higher compression and runs cooler than gasoline. Essentially a nitro motor works on the same principals as a diesel motor, glow plug ignition, high compression, and a slow burning fuel. Add a fast burning fuel into that mix and boom you just turned your motor into a thousand little aluminum chunks.
