Ford Fuel Drain


Filling Diesel in a Petrol Ford is a well-known problem. And what you need to do about it hinges on several things. In case you want to find out what you need to do about this then keep on reading.
These are the most crucial variables to be aware of when deciding on whether to have the car drained:

  1. What level of Diesel have you put in to the Ford, keeping in mind that the fuel tank capacity of your Ford Ka is normally roughly 35 litres?
    1. Hardly any Diesel, as little as 1.75 litres of Diesel in a Petrol Ka will normally not necessarily be a huge problem. Experience has proven to us that anything under 1.75 litres (which is about 5% of the overall fuel tank capacity) is often able to be sufficiently diluted through thoroughly topping up the rest of the tank with the correct fuel.
      It is highly rare to come across a motor vehicle suffering from difficulties due to less than 5% incorrect fuel contamination. Remember that it is infrequently found - definitely not impossible to find. You will discover a few motor vehicles that don't endure any level of contamination whatsoever.
    2. Between 1.75 and 3.5 litres of Diesel in the Ford (from 5 to 10%) is a 50/50 scenario. Our experience has shown us that as many drivers get away with this as those people who don't. Whenever you are deciding whether or not to chance it and just simply top it up consider that it is much like gambling everything on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 3.5 litres of Diesel in your Petrol Ka really should straightaway be drained out seeing as your probability of driving with this amount of contamination is in all likelihood below one in 50 - genuinely big odds.
  2. Put Diesel in a Petrol Ford and drove it: Have you spotted any performance difficulties ever since putting the wrong fuel in the Ka? If you have, get it removed irrespective of the volume of Diesel or even the contamination ratio. Still driving a car that is starting to suffer the consequences of fuel contamination can just result in even more harm affecting your fuel system parts.
  3. Do you want assurance?
    Simply get it emptied. No matter the contamination ratio, there is inevitably a certain level of danger linked with running a Petrol engine on fuel contaminated with the wrong fuel. Possible final outcomes of driving a vehicle on the incorrect fuel normally include the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn or bunged injectors, and the like. These are some of the most typical Diesel in Petrol signs or symptoms, and in the event that you recognise any of them then stop and get it drained right now.

Diesel in Petrol FAQs

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

I put Diesel in a Petrol 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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
