It’s everyone’s worst nightmare putting the wrong fuel into their vehicle and its only diesel fuelled cars that this can be done to (putting petrol into a diesel vehicle) as the diesel fuel nozzle is bigger than the petrol fuel nozzle which means it will not fit into a petrol tank filling hole. Don’t panic if you find yourself in this situation as it is something that can be sorted out here at AE Services in Sutton. Do not drive your vehicle!! The process for correcting Fuel Contamination is not as straight forward as you might think. It can take around three to four hours and unfortunately can be quite costly. The fuel needs to be drained from the tank first, then providing the vehicle has not been driven the fuelling system is then cleaned out with various additives to ensure that no other fuelling components are contaminated. The engineer will then put fuel into the vehicle and turn the car on to make sure it is running correctly. If you have started your vehicle and driven it (the car will not run smoothly with the incorrect fuel) then it could mean that other fuelling components might be contaminated. If this is the case then the fuel filter will need to be replaced. Other contaminated components which will need cleaning or replacing are the fuel injectors, fuel pump, fuel lines and the fuel tank. Here at AE Services in Sutton we strive on keeping costs as low as possible and our engineers will try where possible to clean and save parts rather than replace them.
