Common wrong fuel symptoms
Advice hotline
It’s very easy to misfuel without realising it. Hundreds of motorists do it every day.
If your car won’t start, or runs poorly after filling up, you can check your receipt to see what kind of fuel you bought. If you suspect the wrong fuel in car, call our hotline and describe the symptoms.

Put the wrong fuel in and driven it?
Your car might go a short distance on the right fuel left in the tank. But as the wrong fuel goes through the system it will start to do damage. Our FAQs have more detail about potential problems. There’s really no safe amount of wrong fuel – it needs to be fully removed. If you’re not sure, call our hotline for sensible advice.
Even if your car has been driven after misfuelling and now refuses to start, or if you see white smoke in the exhaust, we deal with any problem caused by misfuelling short of major engine failure. Wrong fuel in car needn’t be a big problem. We fix it on the spot, while you wait.
Wrong fuel mistakes
Sooner or later, most people end up putting diesel in a vehicle that takes petrol, or petrol in diesel car. If you have made the wrong fuel in car mistake, we can come and fix it right away.
First, don’t try to drive on as it will only make matters worse. To avoid any chance of engine damage, don’t drive on.
Call our hotline centre to speak to an expert for advice now. We’ll come to you quickly, and get you back on your journey.

Petrol and Diesel differences
Petrol ignites rapidly with an electrical spark, but diesel combusts more slowly, under the extreme pressure created inside the engine.
Diesel is thicker than petrol, and more oily – diesel engines rely on this oiliness for lubrication. Petrol washes that oil away, leaving the internal components open to rapid wear.
Our own tests show that petrol mixed into diesel also starts to dissolve fuel lines in less than a day. Without proper lubrication, fuel pumps, pistons, cylinders have reduced protection from wear. Our procedure minimises the chance of any damage to engine components.
Engine protection
Petrol destroys the lubricating properties of diesel, leaving fuel pumps, pistons, cylinders with reduced protection from wear. Our procedure minimises the chance of any damage to engine components. Fast action is important to prevent damage to engine components.
Our own tests show that petrol mixed into diesel starts to degrade fuel lines in less than a day. Safety features in modern car designs make it hard to remove all fuel in the tank. FuelFixer pioneered the technology to accomplish this without needing garage work. We have also developed an after-care additive which our technician may recommend in some cases to help minimse any ongoing problems after a misfuel
