Mini Fuel Drain


Putting Diesel in a Petrol Mini is a usual mistake to make. And its solution depends upon a few things. If perhaps you want to find out what you need to do about this then keep on reading.
Right here are the most important variables to consider when deciding on whether to have a fuel drain:

  1. How much Diesel have you put in the Mini, taking into account that the fuel capacity of the Mini One Countryman is normally approximately 47 litres?
    1. A small amount of Diesel, something like 2.35 litres of Diesel in a Petrol One Countryman will most of the time not necessarily be a major problem. Experience has taught us that an amount less than 2.35 litres (roughly 5% of the fuel tank) is sometimes capable of being completely diluted by means of totally topping up the rest of the tank with Petrol.
      It is extremely uncommon to come across an automobile suffering from difficulties due to below 5% incorrect fuel contamination. Bear in mind that it's infrequently found - in no way impossible to encounter. There are actually a few vehicles that won't stand any degree of fuel contamination in the slightest.
    2. Anywhere between 2.35 and 4.7 litres of Diesel in the Mini (from 5 to 10%) is more of a 50/50 condition. Our working experience has revealed that as many motorists get away with this as those people who don't. Whenever deciding on whether or not to chance it and just simply fill it up consider that it is the same thing as gambling all of it on black - you have got a 50/50 possibility of it working out.
    3. Anything in excess of 4.7 litres of Diesel in your Petrol One Countryman really should promptly be removed seeing as your probability of getting away with that amount of contamination is almost certainly less than one in fifty - extremely long odds.
  2. Put Diesel in a Petrol Mini and drove it: Have you spotted any kind of performance problems after putting the incorrect fuel in the One Countryman? If so, get it emptied regardless of the volume of Diesel or the contamination ratio. Still driving a car that is beginning to suffer from the effects of wrong fuel contamination will probably typically end up in even more damage being done to your fuel system components.
  3. Are you looking for assurance?
    Simply get it drained. Whatever the contamination ratio, there is inevitably a certain level of risk connected to operating a Petrol motor on Petrol contaminated with Diesel. Probable results of driving on the incorrect fuel can include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are several of the most common Diesel in Petrol warning signs, and should you observe any of them then stop driving and have it removed as soon as possible.

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.
