What happens when petrol enters a diesel engine

Diesel fuel does more than burn — it lubricates the high-pressure fuel pump and injectors. Petrol acts as a solvent, which can reduce that lubrication. This is why it is important to avoid running the engine once the mistake is noticed. The sooner the engine is stopped, the better the chance of keeping the contamination contained.

Why you must not drive

Driving on petrol in a diesel vehicle can turn a contained problem into a more involved one. The safest action is to stop the engine as soon as you realise the mistake and leave the vehicle where it is. Do not attempt to start it again, and do not try to drive to a workshop. The goal is to keep the contamination from reaching the most expensive components.

How EEK's recovery works

EEK Mechanical operates a tow-to-workshop recovery model. When you call, we dispatch a tow truck to your location — whether that is a forecourt, roadside, home, or car park. The vehicle is collected and transported to a USIFDA-certified workshop, where manufacturer-spec fuel system recovery is completed by qualified technicians using proper recovery equipment. No fuel work is performed at the collection location; the scene is limited to safe loading and transport.

At the workshop, the contaminated fuel is removed, the tank and lines are cleared, and the system is returned to manufacturer specification. Recovery is fully itemised, and costs vary by tow distance, after-hours timing, and vehicle type. You can review the rate card for a transparent breakdown of how pricing is structured.
