Ford Fuel Drain


Filling Petrol in a Diesel Ford is a regularly occurring problem. And exactly what you need to do about it depends on a number of things. If you want to find out what to do about this then read on.
Listed here the key variables to be aware of whenever making a decision whether to have your car drained:

  1. What level of Petrol have you put in to the Ford, considering that the fuel capacity of the Ford Fiesta TDCi is probably about 45 litres?
    1. A modest amount of Petrol, less than 2.25 litres of Petrol in a Diesel Fiesta TDCi will in most situations not really be a big problem. Experience has proven to us that quantities less than 2.25 litres (approximately 5% of the overall fuel tank volume) is very often able to be sufficiently diluted through totally topping the remainder of the tank with Diesel.
      It's relatively rare to encounter a car or truck experiencing difficulties with below 5% wrong fuel contamination. Do not forget that it is very unusual - certainly not impossible to encounter. There are some cars that won't stand any amount of contamination in the slightest.
    2. Anywhere between 2.25 and 4.5 litres of Petrol in the Ford (from 5 to 10%) is really a 50/50 situation. Our experience has proven that as many people get away with this as those people who don't. Any time you are deciding whether to chance it and just simply fill it up remember that it is the same as gambling your car on black - you have got a 50/50 chance of it working out.
    3. Anything in excess of 4.5 litres of Petrol in a Diesel Fiesta TDCi should really straight away be drained out seeing that your likelihood of succeeding with this quantity of contamination is probably less than one in fifty - genuinely long odds.
  2. Put some Petrol in a Diesel Ford and drove it: Have you spotted any performance concerns ever since putting the incorrect fuel in the Fiesta TDCi? In that case, have it drained regardless of the volume of Petrol or the contamination ratio. Continuing to drive driving a car that is now starting to suffer the effect of fuel contamination will probably typically bring about even more damage affecting the fuel system components.
  3. Do you want assurance?
    You should get it drained. Regardless of contamination percentage, there is invariably some degree of danger linked with running a Diesel engine on fuel contaminated with the incorrect fuel. Possible final outcomes of driving a vehicle on the wrong fuel can include the engine not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn out or bunged injectors, and so on. These are a few of the commonest Petrol in Diesel signs and symptoms, and in the event that you recognise any of them cease driving and get it removed right now.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?


No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?


This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
