I put diesel in my petrol car, what should I do?

Do not turn the key in the ignition or start the engine. Diesel is heavier and unrefined compared to petrol, meaning it won't ignite properly in a petrol engine and will quickly clog fuel lines, injectors, and spark plugs. Leave the vehicle switched off and call Wrong Fuel In Car Rescue Suffolk immediately on +447904731886 for emergency mobile fuel drainage.

Is putting diesel in a petrol engine dangerous or costly?

Putting diesel in a petrol car is less destructive than putting petrol in a diesel, but running the engine will cause severe misfiring, heavy smoke, soot fouling on spark plugs, and potential catalytic converter damage. A complete professional system drain and petrol flush cleared on-site prevents long-term engine harm.

How long does a diesel in petrol fuel drain service take in Suffolk?

Our emergency mobile vans reach roadsides and petrol forecourts across Suffolk in 30 to 45 minutes on average. Draining the unburnt diesel, flushing the fuel system with fresh petrol, and restarting the vehicle typically takes 20 to 35 minutes on-site.

If you have accidentally filled your petrol vehicle with diesel fuel anywhere in Suffolk, keep your keys out of the ignition.

Our mobile fuel drain engineers are on standby 24/7 across all Suffolk IP postcodes to reach your location in 30 to 45 minutes, siphon out the diesel, flush your lines with fresh petrol, and get you back on the road.

Fast Mobile Diesel-in-Petrol Extraction & Spark Plug Cleaning

Because diesel nozzles are usually larger than petrol filler necks, putting diesel in a petrol car is less common, but it still happens frequently. If you catch the mistake at the pump, leave your vehicle switched off. Siphoning the fuel out of an unstarted tank takes under 30 minutes and completely prevents engine contamination.

If you drove away from the forecourt and your car began to smoke, splutter, or stall, our fully equipped mobile response vans bring specialized extraction tools straight to your driveway, forecourt, or layby to perform a full system flush.

Frequently Asked Questions About Diesel in Petrol Engines

What happens if you put diesel in a petrol car?

Diesel is heavier and oilier than petrol. It will not ignite properly through a petrol spark plug, causing the engine to misfire, smoke heavily, lose power, and eventually stall as the injectors clog with unburnt fuel.

Can diesel ruin a petrol engine?

Unlike petrol in a diesel engine (which destroys the fuel pump), diesel rarely causes catastrophic mechanical damage to a petrol engine. However, leaving diesel in the system can permanently ruin your catalytic converter and oxygen sensors if not drained immediately.

How do you fix diesel in a petrol car?

Our technician drains the contaminated fuel tank using spark-safe equipment, flushes clean unleaded petrol through the fuel lines and fuel rail to remove oily residue, cleans or dries the spark plugs, refills the tank with fresh petrol, and restarts the vehicle.
