Diesel engines consume less fuel than petrol engines, all else being equal. Diesel fuel's higher energy density and diesel engines' superior thermal efficiency are the main reasons. Diesel fuel has more energy per litre than petrol, and diesel engines utilise that energy more efficiently.
Higher compression ratios improve thermal efficiency and allow diesel engines to extract more energy from each fuel unit. Diesel vehicles get better fuel efficiency and travel farther per gallon or litre than petrol vehicles of equal size and performance.
The choice between diesel and petrol automobiles depends on fuel economy, driving patterns, environmental concerns, and local fuel prices and availability.
