Ford Fuel Drain


Filling up with Diesel in a Petrol Ford is a regularly occurring error. And exactly what you want to do about it depends upon several factors. If perhaps you would like to know what you should do about it then read on.
These are the key factors to consider when deciding whether to get the car drained:

  1. What level of Diesel did you put in to the Ford, taking into consideration that the fuel capacity of the Ford B-Max is probably approximately 48 litres?
    1. A small quantity of Diesel, as little as 2.4 litres of Diesel in a Petrol B-Max will usually not be a huge problem. Experience has taught us that anything less than 2.4 litres (which is 5% of the overall fuel tank volume) is oftentimes capable of being completely diluted through wholly filling the remainder of the tank with Petrol.
      It is extremely rare to come across a vehicle going through problems because of under 5% incorrect fuel contamination. Keep in mind it is unusual - definitely not impossible to encounter. There are actually certain motor vehicles that don't stand any amount of contamination whatsoever.
    2. Between 2.4 and 4.8 litres of Diesel in the Ford (5 to 10%) is a 50/50 scenario. Our working experience has shown that as many motorists get away with this as those people who break down. Whenever you are deciding on whether to risk it and just fill it up consider that it is the same as betting all of it on black - you have got a 50/50 chance of it being ok.
    3. Anything over 4.8 litres of Diesel in a Petrol B-Max should really right away be drained out since your likelihood of getting away with this amount of contamination is undoubtedly less than one in fifty - seriously huge odds.
  2. Put Diesel in a Petrol Ford and drove it: Have you noted any performance problems as a result of putting the bad fuel in your B-Max? If you have, have it removed irrespective of the amount of Diesel or even the contamination ratio. Still driving an automobile that is now beginning to suffer the effect of fuel contamination can definitely result in increasing amounts of harm being done to the fuel system parts.
  3. Do you want assurance?
    You should get it emptied. Whatever the contamination ratio, there is always some degree of risk affiliated with running a Petrol motor on fuel contaminated with the incorrect fuel. Likely implications of driving a car on the wrong fuel can include the engine not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn or clogged injectors, and so on. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you detect any of them then cease driving and get it removed immediately.

Stay away from having any general so-and-so to try to drain your automobile. We are Ford experts and have the skills and practical experience needed to make sure that you are back on the road with minimal hassle or trouble.

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.
