Why not use petrol in diesel engine?

Using petrol in a diesel engine can cause severe mechanical damage and expensive repairs, making it extremely unsafe and inefficient. Diesel engines are specifically designed to operate with diesel fuel, which has very different chemical and combustion properties compared to petrol. Diesel fuel is thicker, more lubricating, and ignites through compression rather than a spark. Petrol, on the other hand, is lighter, less lubricating, and ignites at a much lower temperature.

When petrol is introduced into a diesel engine, it disrupts the precise combustion process. Petrol reduces the lubrication inside the fuel system, leading to increased friction and potential damage to components such as the fuel pump and injectors. Additionally, because petrol ignites too quickly under compression, it can cause pre-ignition or “knocking,” resulting in violent combustion that can damage pistons, valves, and cylinder heads.

Even small amounts of petrol contamination can compromise engine performance, reduce fuel efficiency, and increase emissions. In severe cases, it can cause complete engine failure. For this reason, it’s critical to always ensure the correct fuel is used. PETRO Industrial (petroinddotcom) strongly advises checking fuel labels carefully and implementing proper refueling procedures to protect your diesel engine and maintain peak performance.
