Treibstoff and Kraftstoff both refer to combustible substances used for propulsion. Kraftstoff is used especially as a factual, technical term for the energy source of an engine. Treibstoff is more broadly related to propulsion and therefore also fits aircraft and rockets particularly well.

Before the trip, the technician checks the fuel in the car's tank.
