Ford Fuel Drain


Filling up with Diesel in a Petrol Ford is a regular error. And its solution hinges on a variety of things. In the event that you want to find out what to do about it then stay with me.
Listed here are the most important variables to consider when deciding whether to have a fuel drain:

  1. What level of Diesel have you put in the Ford, keeping in mind that the fuel tank capacity of the Ford Fiesta ST is usually about 45 litres?
    1. A tiny quantity of Diesel, as little as 2.25 litres of Diesel in a Petrol Fiesta ST will normally not be a huge problem. Experience has taught us that an amount less than 2.25 litres (which is about 5% of the whole fuel tank capacity) is oftentimes able to be adequately diluted through thoroughly filling the tank with Petrol.
      It is highly rare to encounter a motor vehicle suffering from difficulties due to less than 5% incorrect fuel contamination. Keep in mind that it's uncommon - certainly not impossible to find. You will discover certain cars that don't stand any quantity of contamination in the slightest.
    2. In between 2.25 and 4.5 litres of Diesel in the Ford (5 to 10%) is more of a 50/50 condition. Our expertise has proven that as many people get away with it as all those who don't. Any time you are figuring out whether or not to risk it and just simply fill it up bear in mind 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 Diesel in a Petrol Fiesta ST should as soon as possible be drained out seeing that your probability of getting away with this amount of contamination is more than likely below one in 50 - definitely huge odds.
  2. Put Diesel in a Petrol Ford and drove it: Have you spotted any kind of performance problems since putting the incorrect fuel in your Fiesta ST? In that case, have it removed irrespective of the amount of Diesel or even the contamination percentage. Continually running a vehicle that is now starting to suffer from the effect of wrong fuel contamination can definitely cause increasing amounts of harm affecting your fuel system.
  3. Would you like peace of mind?
    In that case get it removed. Whatever the contamination percentage, there is invariably a certain level of risk resulting from operating a Petrol motor on fuel contaminated with the incorrect fuel. Possible final outcomes of driving on the incorrect fuel can include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, damaged or bunged injectors, and so forth. These are some of the most typical Diesel in Petrol warning signs, and should you detect any of them then stop driving and have 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.
