Gasoline engines use spark plugs to ignite a mixture of fuel and air, while diesel engines rely on compression to ignite the fuel.
Petrol engines typically have higher RPMs and are more suitable for lighter vehicles, while diesel engines have more torque and are better for heavy-duty applications.
Diesel engines are more fuel-efficient than gasoline engines due to the higher energy density of diesel fuel.
Diesel engines produce more torque at lower RPMs compared to gasoline engines, making them better for towing and hauling.
Diesel engines tend to have a longer lifespan and require less maintenance compared to gasoline engines.
