How long you can drive with mixed fuel will depend on factors such as your car’s make and model, its fuel type – and the quantity of the wrong fuel that was added. However, we would not recommend putting this to the test; the longer you drive with mixed fuel, the more likely your car will develop a serious mechanical fault.
If you are driving and have a suspicion that you have recently added the wrong type of fuel, do not leave anything to chance. Pull over when it is safe to do so. Then, contact a wrong fuel recovery specialist.
