Mini Fuel Drain


Filling up with Diesel in a Petrol Mini is a regular mistake to make. And exactly what you need to do about it depends upon a few factors. Assuming you would like to know what it is advisable to do about this then please read on.
Let us discuss the key factors to be aware of whenever deciding on whether or not to get a fuel drain:

  1. What amount of Diesel did you put into the Mini, considering that the fuel capacity of your Mini Cooper Countryman is probably about 47 litres?
    1. A small quantity of Diesel, something like 2.35 litres of Diesel in a Petrol Cooper Countryman will more often than not not be a significant problem. Experience has proven to us that quantities less than 2.35 litres (about 5% of the overall fuel tank volume) is generally capable of being sufficiently diluted through wholly filling the tank with the right fuel.
      It is relatively unusual to find a motor vehicle suffering from issues because of lower than 5% wrong fuel contamination. Keep in mind that it's unusual - definitely not impossible to encounter. There are some automobiles that will not endure any quantity of fuel contamination at all.
    2. Somewhere between 2.35 and 4.7 litres of Diesel in the Mini (5 to 10%) is really a 50/50 scenario. Our working experience has confirmed that as many motorists get away with this as those people who don't. Any time you're deciding upon whether to risk it and just simply fill it up remember that it is just like gambling your car on black - you have got a 50/50 possibility of it working out.
    3. Anything over 4.7 litres of Diesel in your Petrol Cooper Countryman ought to straight away be drained out seeing that your probability of succeeding with that level of contamination is more than likely lower than one in fifty - extremely long odds.
  2. Put Diesel in a Petrol Mini and drove it: Have you noted any performance difficulties as a result of putting the wrong fuel in your Cooper Countryman? If that's the case, get it removed no matter the quantity of Diesel or even the contamination percentage. Proceeding to drive running a vehicle that is now beginning to suffer the consequences of fuel contamination will probably definitely lead to even more harm affecting your fuel system.
  3. Would you like reassurance?
    Then simply just get it drained. Regardless of contamination ratio, there is always some degree of risk connected with driving a Petrol engine on Petrol contaminated with Diesel. Likely outcomes of driving on the incorrect fuel can include the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are a few of the most common Diesel in Petrol symptoms, and should you observe any of them stop driving and get it removed 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.
