Mini Fuel Drain


Filling up with Petrol in a Diesel Mini is a very common mistake to make. And its remedy will depend on several different things. If perhaps you would like to find out what you must do to fix it then keep reading.
Let us discuss the main variables to consider when determining whether or not to get a fuel drain:

  1. Exactly how much Petrol have you put in to the Mini, keeping in mind that the fuel capacity of the Mini Cooper D Countryman is most likely around 47 litres?
    1. A small amount of Petrol, less than 2.35 litres of Petrol in a Diesel Cooper D Countryman will most of the time not be a big problem. Experience has proven to us that an amount less than 2.35 litres (close to 5% of the whole fuel tank capacity) is often capable of being completely diluted simply by completely filling up the rest of the tank with the right fuel.
      It is very unusual to come across a car or truck suffering from difficulties with lower than 5% wrong fuel contamination. Keep in mind that it is rare - definitely not impossible to encounter. There are actually a few vehicles that will not endure any amount of contamination at all.
    2. Somewhere between 2.35 and 4.7 litres of Petrol in the Mini (5 to 10%) is more of a 50/50 condition. Our experience has confirmed that as many drivers get away with this as those who break down. Any time you're trying to decide whether to risk it and simply top it up remember that it is just like gambling it all on black - you have a 50/50 possibility of it being ok.
    3. Anything above 4.7 litres of Petrol in a Diesel Cooper D Countryman ought to straightaway be removed because your probability of succeeding with that quantity of contamination is in all likelihood below one in fifty - extremely huge odds.
  2. Put Petrol in a Diesel Mini and drove it: Have you noticed any kind of performance issues ever since putting the bad fuel in your Cooper D Countryman? In that case, get it removed irrespective of the volume of Petrol or even the contamination percentage. Proceeding to drive running a motor vehicle that is already starting to suffer from the effects of wrong fuel contamination will only bring about increasing amounts of damage being done to your fuel system.
  3. Would you like peace of mind?
    Then simply just get it drained. No matter the contamination percentage, there is invariably some extent of risk caused by driving a Diesel engine on Diesel contaminated with Petrol. Possible outcomes of driving a vehicle on the wrong fuel include things like the motor refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, damaged or bunged injectors, and so on. These are some of the commonest Petrol in Diesel signs and symptoms, and should you observe any of them stop and get it drained asap.

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.
