Mini Fuel Drain


Filling up with Petrol in a Diesel Mini is a fairly typical mistake to make. And exactly what you should do about it is dependent upon several things. Assuming you would like to know what it is advisable to do to fix it then stay with me.
Listed below are the key factors to think about whenever deciding whether to have a fuel drain:

  1. How much Petrol have you put into the Mini, taking into consideration that the fuel tank capacity of your Mini One D Clubman is usually around 40 litres?
    1. A tiny quantity of Petrol, as little as 2 litres of Petrol in a Diesel One D Clubman will usually not be a significant problem. Experience has taught us that anything less than 2 litres (about 5% of the fuel tank capacity) is very often able to be completely diluted through completely topping the remainder of the tank with the right fuel.
      It is highly rare to find a motor vehicle suffering from problems with lower than 5% wrong fuel contamination. Keep in mind it is infrequent - definitely not impossible to encounter. There are actually some motor vehicles that don't stand any amount of fuel contamination whatsoever.
    2. In between 2 and 4 litres of Petrol in the Mini (5 to 10%) is really a 50/50 scenario. Our working experience has shown us that as many drivers get away with this as all those who don't. When deciding whether or not to chance it and simply top it up consider that it is very much like gambling all of it on black - you've got a 50/50 possibility of it working.
    3. Anything above 4 litres of Petrol in a Diesel One D Clubman ought to straightaway be drained seeing that your likelihood of succeeding with that amount of contamination is undoubtedly lower than one in fifty - seriously long odds.
  2. Put some Petrol in a Diesel Mini and drove it: Have you noticed any performance issues ever since putting the wrong fuel in the One D Clubman? If that's the case, have it removed regardless of the volume of Petrol or the contamination percentage. Continuing to drive driving a vehicle that is starting to suffer from the consequences of wrong fuel contamination can just result in even more harm being done to your fuel system parts.
  3. Are you interested in security?
    You should get it emptied. Whatever the contamination ratio, there is always some degree of danger caused by operating a Diesel motor on fuel contaminated with the wrong fuel. Probable outcomes of driving on the incorrect fuel include the motor refusing to start, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are some of the most typical Petrol in Diesel signs and symptoms, and should you recognise any of them stop and get it drained immediately.

Petrol in Diesel Questions

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.
