Petrol in diesel car problems

Any vehicle, any time. Just call us: we’ll get you going again, fast

Petrol needs an electrical spark to ignite, but diesel ignites under pressure, with no spark needed. The two fuels work very differently. Petrol in a diesel engine can dissolve the oils needed to lubricate the engine, but diesel in a petrol engine can clog up the very fine nozzles that help to create good combustion. The wrong fuel, either way, will damage your engine over time. But if you’ve just misfueled and not the car for any distance, all you need to do is to get the wrong fuel out. We do also recommend an additive which our engineer can supply – this will more thoroughly clean the working parts of your engine.

To avoid any chance of damage to your diesel or petrol engine, don’t drive on. Call us now.


Expert care, and no garage bills, no nasty surprises

Our engineers really are experts: they regularly deal with the wrong fuel in makes and models which other roadside assistance companies say “have to be towed to a main dealer” (with the prospect of massive and unnecessary bills). Even if your car has been driven after misfuelling and now refuses to start,  if the problem was caused by misfuelling, we fix it. Then and there, and get you on the road again.
