A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, AC usage, fuel and rolling resistance. There have been advances in all areas of vehicle design in recent decades. Fuel efficiency of vehicles can also be improved by careful maintenance and driving habits. [3]

Natural gas can yield an overall efficiency of about 200 g/kWh. [2] Average fuel consumption values are 160–180 g/kWh for slower two-stroke diesel cargo ship engines using fuel oil, reaching up to 55% efficiency at 300 rpm; 195–210 g/kWh for turbodiesel passenger cars; 195–225 g/kWh for trucks; and 250–350 g/kWh for naturally aspirated ...
