Diesel and petrol have several key differences. Diesel engines are generally more fuel-efficient and provide more torque, making them ideal for heavy-duty vehicles. Petrol engines, on the other hand, are typically quieter, offer better acceleration, and are often less expensive to buy and maintain. However, petrol engines tend to have higher exhaust emissions. Your choice between the two should depend on your driving needs and environmental considerations.
