Common Fuel Mistakes We Fix Every Day
Petrol in a Diesel Car
Putting petrol in a diesel car is one of the most common misfuelling mistakes—and one of the most damaging if not dealt with quickly. Petrol removes the vital lubrication diesel engines rely on, which can lead to fuel pump and injector failure.
At Fuel Drain Experts, we provide 24/7 emergency petrol-in-diesel fuel drainage across Glasgow, Edinburgh, and all of Scotland. Our mobile technicians will safely drain the fuel tank, flush the entire fuel system, and refill with the correct diesel fuel, helping to prevent expensive engine repairs.
Diesel in a Petrol Car
If you’ve put diesel in a petrol car, do not start the engine. Diesel is thicker and heavier than petrol and can block fuel filters, foul spark plugs, and cause misfiring, loss of power, or breakdowns.
Our specialist team offers fast diesel-in-petrol removal services throughout Scotland, including Glasgow and Edinburgh. We’ll come to your location, remove the contaminated fuel, clean the system, and get your vehicle running safely again—quickly and professionally.
AdBlue in the Diesel Tank
AdBlue in the fuel tank is a serious issue that requires immediate attention. AdBlue is a urea-based solution designed solely for your vehicle’s emissions (SCR) system. When introduced into the diesel tank, it can crystallise and corrode fuel lines, pumps, and injectors, potentially leading to major engine failure.
Fuel Drain Experts provide expert AdBlue fuel tank cleaning and system restoration across Glasgow, Edinburgh, and Scotland. Our engineers will fully drain, clean, and flush the fuel system, ensuring your vehicle is safe to drive and protected from long-term damage.

Symptoms of Misfuelling – Know the Warning Signs
If you’ve accidentally put the wrong fuel in your vehicle and the engine has already been started, you may begin to notice several warning signs that misfuelling has affected the fuel system. These symptoms can vary depending on the type of vehicle and the amount of incorrect fuel added, but they often include difficulty starting the engine, engine knocking, juddering or misfiring, smoke coming from the exhaust, or dashboard warning lights such as the engine management light. Drivers may also experience a sudden loss of power, hesitation when accelerating, stalling, unusual fuel smells, or unfamiliar engine noises while driving.
If any of these symptoms occur, it is important to pull over safely and switch the engine off immediately. Continuing to drive with contaminated fuel can circulate the incorrect fuel throughout the system, affecting the fuel pump, injectors, and engine components. Acting quickly can make a significant difference in preventing serious mechanical damage. Contact Fuel Drain Experts as soon as possible so that a trained technician can safely remove the contaminated fuel and protect your vehicle from further problems.
