WHAT HAPPENS IF I'VE PUT PETROL IN DIESEL
Loss of Lubrication (The Main Problem)
-
Diesel fuel is naturally oily and acts as a lubricant for the high-pressure fuel pump and injectors, which are the most expensive parts of the fuel system.
-
Petrol is a solvent (a degreaser). When it mixes with the diesel, it drastically reduces the lubricity of the fuel.
-
If you start the engine, the pump and injectors operate without proper lubrication, leading to metal-on-metal friction. This can cause the high-pressure fuel pump to grind and fail very quickly (sometimes within minutes), shedding tiny metal fragments throughout the entire fuel system.
​
If you drive the car, the following symptoms may occur:
-
Loud knocking or rattling noises from the engine.
-
Excessive white or black smoke from the exhaust.
-
Sluggish acceleration and a lack of power.
-
The engine misfiring, cutting out, or stalling completely.
-
The Engine Management Light (EML) illuminating.
