Either by Petrol/Nitro or electric.
Any nitro, ranging between 5% and 30% nitro. Anything more would clog the engine.
There are on road and off road models of nitro RC trucks. Choose an off road model for dirt roads. More information is available at http://www.rccartalk.com/nitro-rc-cars.html
One difference is that a nitro RC car runs on nitromethane and a petrol one runs on a mixture of petrol or gasoline and oil. Another is a nitro RC car will run longer on a gallon of fuel.
