WHAT HAPPENS IF I'VE PUT DIESEL IN PETROL
Putting diesel fuel into a petrol (gasoline) car is generally considered less catastrophic than the reverse, but it can still cause significant and expensive problems if the engine is run.
Incomplete Combustion (The Main Problem)
-
Diesel is a heavier, oilier fuel designed to ignite under high compression (heat), while petrol ignites via a spark plug.
-
When diesel enters a petrol engine, it does not burn efficiently because the temperature and spark ignition process are wrong for its properties.
-
The unburnt fuel contaminates the spark plugs, injectors, and fuel system.
Symptoms if You Start the Engine
-
If you drive the car, the following symptoms will quickly become apparent:
-
Engine Misfires and Rough Idling: The engine will stutter and run very poorly because the fuel isn't igniting correctly.
-
Excessive Smoke: You will see thick, usually white or black smoke, coming from the exhaust as the unburnt diesel is forced out of the system.
-
Loss of Power and Stalling: The engine will lose significant power and may cut out or stall completely shortly after starting.
-
Difficulty Restarting: Once the engine is off, it will likely struggle or fail to restart.
