Q– I’ve put Diesel in a Petrol car. What do I do now?
Generally, a small amount of Diesel in your Petrol car should not damage the engine, as long as you have not turned on the ignition or started the engine. If you’ve added more than 5% of Diesel (2.5 litres in a 50 litre tank). The fuel tank Must be fully drained out and replenished with fresh petrol. If you’ve added less than 5% diesel – You could fill the fuel tank to the max with petrol (at your own risk), With little chance of causing any lasting damage. Unless your manufacturer’s warranty (should you have one) says otherwise.
Q– I’ve put Petrol in my Diesel car what is the potential damage?
Some advanced fuel system seals can be affected by the compounds in petrol too. As a rule of thumb the further the contaminated petrol goes in the diesel fuel system the more expensive the repair costs will be. Some manufacturers advise that seals and filters should be renewed even if the engine has not been run. This particular remedial action will not be nearly as expensive as having to replace the entire engine.
The more modern common rail diesel systems are particularly vulnerable – if petrol works it way in to the high pressure fuel pump, the metal to metal wear creates heat & debris, if this gets further in to system you may also have to replace the high-pressure fuel pump, injectors, fuel rail, line filters and the fuel tank too. This shows what a nightmare can be created by the simple act of putting the wrong fuel in your car. Many diesel engines use a low-pressure electric pump in the tank or sender unit and this begins to work as soon as the ignition is switched on, circulating the contaminated fuel through the pump and rail – so if you’ve put the wrong fuel in your car it’s important not to turn the ignition on and the engine must certainly not be started.
