The smoke is produced by pumping a biodegradable, paraffin-based oil directly into the exhaust nozzles of the aircraft where the oil is instantly vapourized into smoke. The smoke provides a traceable path for spectators to follow, so they can see the flight profile that has been flown. It also enhances safety of flight by providing a valuable means by which the solo pilots can see each other during opposing manoeuvres and conditions of lowered visibility or haze. The smoke poses no hazard to the environment.
They used to use diesel fuel but it never really completely burns and leaves a big mess.
Remote control planes sometimes use mineral oil or make up a mixture with kerosene.
The oil has to burn quickly or it just gets sprayed out as liquid.
I use Super*Dri® Aviation Smoke Oil with some fragrance, yes fragrance, so it doesn't have the sharp smell. The airport likes to watch as I practise with the grape oil.
They do not use vegetable oil. The flash point is too high, and if they do, it makes a big mess as it does not burn well.

"Airshow Smoke - created by a miniature high-speed pump transferring very light-weight paraffin-based oil from a reservoir in the plane to the final stage of the exhaust system, where it "smolders", but does not burn. This oil, usually Texaco "Corvus" oil has a very high flash point, and is biodegradable. The smoke leaves a trail across the sky that lets spectators appreciate the geometry of the aerobatic performance."
Pulled from site below. Good question.

Two type of smokes are released.
1. Unburned fuel.
2. Canister(pressurised air with dye) on the wing and other parts of the craft, to give some effect and make it more visible in the sky and leave a trail.

Older airplanes use an oil that is much like engine oil. Some jets use a liquid that is pretty much the same thing as in smoke machines, only in vastly greater quantities.

vegetable oil the warm it and pressurize it till its just below the combustion stage and then they spray it out at high pressure its Eco friendly and non toxic plus safe if anything should go wrong with the system
