Mobile Fuel Doctor specialists & mobile mechanics in London

Accidentally putting the wrong fuel in your vehicle can be alarming, but it's more common than you might think. Whether you've put petrol into a diesel engine, diesel into a petrol engine, or even AdBlue into a diesel tank, don't panic! In the UK, an average of 410 drivers misfuel their cars daily. The key is to act quickly. If you haven't started your engine yet, don't! If you've already started it, turn it off immediately. Running the engine with the wrong fuel can cause serious damage to the fuel system and the engine itself. In most cases, your fuel tank must be drained and flushed thoroughly before you can safely drive the car again.

How to Request a Fuel Technician

Our team is experienced in handling all vehicle types and is well-trained to resolve misfuelling incidents quickly and efficiently.

Misfuelling on a Motorway

You'll need to call for recovery first if you realize you've put the wrong fuel in your vehicle while on a motorway. Due to safety regulations, it's not possible to carry out a fuel drain directly on the motorway , even if you're on the hard shoulder. We can prioritize your booking and arrange for your vehicle to be towed to a safe location where the fuel drain can be performed .

Impact on Your Engine and ECU

One potential consequence of running your vehicle with the wrong fuel is damage to the Engine Control Unit (ECU), which manages your vehicle's electrical and mechanical systems. The ECU is sensitive to issues like misfiring caused by incorrect fuel in the injectors . Some vehicle models may automatically shut down as a precaution. After the wrong fuel is drained , our technicians can reset your ECU on the spot using advanced diagnostic tools, saving you a costly trip to the dealership.

Warranty Concerns

Many drivers worry that using an independent service like Mobile Fuel Doctor will invalidate their vehicle's warranty. In most cases, misfuelling won't affect your warranty. While some manufacturers might suggest otherwise, rest assured that our technicians use certified, compliant fuel-draining equipment that won't compromise your vehicle's components. Our service adheres to all relevant safety and environmental regulations, including ATEX, DSEAR, and HSE standards, so you can feel confident that your car is in safe hands.
