Why It Happens & The Risk
Diesel nozzles are typically wider than petrol filler necks, making it harder to accidentally add — but it does happen, particularly in hire cars or unfamiliar vehicles. Once diesel enters a petrol tank, it begins coating the fuel system with a thick, oily film.
If the engine is started, diesel residue bakes onto spark plugs, fouls injectors, and can cause the engine to stall permanently. The plugs may require replacement in addition to the drain — but we carry spares and handle all of it at your location.
