What happens when you put petrol in diesel car Bury St Edmunds?
Using petrol in diesel car is a much more serious problem and could result in expensive and potentially permanent damage to your engine. Petrol will increase the friction between the various parts and components of your engine – unlike diesel which is a more lubricating fuel – and this is what will cause damage.

Put petrol in diesel car Bury St Edmunds?
Turning the key is the biggest mistake you can make, as even if you don’t actually start the engine, illuminating the dashboard lights could mean your fuel pump whirrs into life. It’s supposed to prime the engine with diesel before it starts, but instead could be sucking petrol up the fuel lines. This means they’ll need draining and flushing as well as the fuel tank. If you get as far as starting the engine, there’s a whole lot more that can go wrong besides.
Unleaded in diesel tank: components
Modern diesel engines employ lots of technology to eke out their impressive mpg figures and minimise emissions, including expensive high-pressure fuel pumps, and common rail injectors with very fine tolerances.
Those fuel pumps are lubricated by diesel fuel itself, as it passes through. Replace that diesel with petrol, and its solvent properties mean the lubrication effect is eliminated too. A fuel pump running without lubrication will soon begin to create internal friction as its metal surfaces grind together. It will then begin to disintegrate, and that in turn creates swarf – potentially microscopic particles of metal that can do even more damage to your car's engine further down the line.

How petrol harms a diesel engine
-
Once the petrol has stripped the lubricant out of the fuel pump, tiny fragments of metal from the parts rubbing together will enter the fuel system. Many of these will be caught by the fuel filter. However, some will make it all the way to the injectors and that’s when the real damage is done.
-
Modern diesel injectors work to very fine tolerances, releasing a fine spray of fuel into the cylinders. Even the tiniest foreign body will block the jets, throwing everything out of kilter. It could cause a misfire or the engine might even seize.
It’s easier to put petrol into a diesel car due to the size of the nozzles - a diesel car has a wider opening on its fuel tank than a petrol car.
