Putting Diesel in a Petrol car is generally not a major issue, as long as you have it removed. In fact, if you have only put a very small amount of Diesel in your Petrol tank (under 5%) you might even get away with running the car. Our professional advice, however, is always to have the mixed fuel removed from your car as soon as possible for complete peace of mind. Even if you are not sure what to do and want advice about the wrong fuel in your car you should seek professional help. Call our National Control Room on one of the numbers above for further advice.
In line with car manufacturers' recommendations, Fuel Doctor advise that any Petrol fuel contaminated with Diesel should be removed from the tank and replaced with clean fuel before the ignition is turned on and the car started. In some cases this may not be possible but care and consideration should be taken. The best course of action is to seek advice from professionals who have a full understanding of the mechanics and electronics involved with the fuel system.
Diesel is an oil and a much less flammable substance than Petrol. In fact, it is unlikely to ignite properly in a Petrol engine, if at all. The result is that your car is not going to run for very long if you have filled up with Diesel instead of Petrol. If the engine does run on the mixed fuel then it will most likely produce some very thick smoke and prolonged exposure to this could potentially damage your car’s catalytic converter and other emission control components. The reality is that the engine will most likely stop quite soon after you fill up with the wrong fuel because the spark plugs will become coated in the oily Diesel – These may require replacing before the vehicle will run properly, but this is very rare. As the car fuel pumps are not designed to be exposed to Diesel, parts like the seals and fittings may also be damaged too. This would need to be checked by a fully qualified fuel drain technician. As a general rule, if the wrong fuel is removed from your car with the minimum of delay there is unlikely to be any lasting damage.
