Ford Fuel Drain


Filling up with Diesel in a Petrol Ford is a fairly typical mistake. And what you should do about it is based on several factors. In the event that you would like to know what you need to do to fix it then keep on reading.
Listed here are the key factors to to consider when deciding on whether or not to get it drained:

  1. How much Diesel have you put in to the Ford, taking into consideration that the fuel capacity of the Ford Cougar is probably approximately 57 litres?
    1. A tiny quantity of Diesel, something like 2.85 litres of Diesel in a Petrol Cougar will in most cases not necessarily be a significant problem. Experience has demonstrated to us that an amount less than 2.85 litres (roughly 5% of the entire fuel tank) is usually able to be sufficiently diluted by means of totally filling up the rest of the tank with the correct fuel.
      It is extremely unusual to find a motor vehicle having problems with less than 5% incorrect fuel contamination. Be aware that it is infrequently found - not impossible to encounter. There are some vehicles that will not stand any degree of contamination at all.
    2. Anywhere between 2.85 and 5.7 litres of Diesel in the Ford (5 to 10%) is really a 50/50 situation. Our expertise has confirmed that as many people get away with it as those people who don't. Whenever trying to decide whether or not to risk it and simply top it up recognise that it is much like gambling everything on black - you will have a 50/50 chance of it working.
    3. Anything over 5.7 litres of Diesel in a Petrol Cougar should right away be drained out because your likelihood of succeeding with this level of contamination is undoubtedly less than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Ford and drove it: Have you noted any kind of performance difficulties since putting the incorrect fuel in the Cougar? If so, get it removed regardless of the quantity of Diesel or the contamination ratio. Still driving an automobile that is currently beginning to suffer from the consequences of wrong fuel contamination can typically be responsible for increasing amounts of harm affecting the fuel system components.
  3. Are you looking for peace of mind?
    Then get it drained. No matter the contamination ratio, there is always a certain level of threat linked with running a Petrol engine on Petrol contaminated with Diesel. Likely final outcomes of driving on the wrong fuel normally include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, and the like. These are some of the most common Diesel in Petrol signs and symptoms, and in the event that you observe any of them stop driving and get it drained asap.

Diesel in Petrol Questions

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.
