The Service

Professional in - Process Details

When petrol enters a diesel fuel system it strips the lubrication from the high-pressure fuel pump. The most immediate symptom is often a metallic knocking or rattling from the engine bay — this is the sound of metal grinding against metal as lubrication fails. Other symptoms include sudden loss of power, excessive white or black smoke from the exhaust, and illumination of the engine management warning light.

The critical thing to understand is that these symptoms may only appear after several miles of driving — by which point significant damage may already be occurring. If you have any reason to believe petrol was added, pull over and switch off the engine immediately, even if it is currently running normally. Early intervention is the difference between a £200 drain and a £5,000 pump replacement.

FAQs

Common Questions

What does petrol-in-diesel sound like?expand_more
The most distinctive sound is a metallic knocking or rattling from the engine — often described as a tapping or clattering. This is caused by the high-pressure fuel pump running without adequate lubrication. You may also notice the engine feels rough or misfiring during acceleration.
Can I smell petrol in a diesel car that has been misfueled?expand_more
Yes — if you suspect a misfuel, sniff at the filler cap. Petrol has a distinctly different, sharper smell compared to diesel. If you smell petrol when you know you filled with diesel, call us immediately.
What if my car only ran for a few seconds on the contaminated fuel?expand_more
Even a few seconds is enough to push contaminated fuel through the fuel lines into the high-pressure system. However, the shorter the run time, the higher the chance of a successful drain without component replacement. Stop now and call us.
Will I know if contamination is petrol or something else?expand_more
Our technicians carry diagnostic equipment that can confirm the exact contamination type on arrival. Just tell us your symptoms and when you last filled up and we will diagnose it on site.
Is it possible to have symptoms but not have misfueled?expand_more
Yes — some symptoms like rough running can have other causes. If you are not sure whether you misfueled, call us anyway. We would rather diagnose and confirm it is not a misfuel than have you drive further on contaminated fuel.
