Mini Fuel Drain


Putting Diesel in a Petrol Mini is a fairly typical error. And its solution is based on a variety of things. In the event that you want to find out what you have to do about this then continue reading.
Listed below are the key factors to be aware of whenever choosing whether or not to have your car drained:

  1. What level of Diesel have you put in the Mini, considering that the fuel tank capacity of your Mini Cooper is probably around 50 litres?
    1. A tiny amount of Diesel, something like 2.5 litres of Diesel in a Petrol Cooper will generally not be a major problem. Experience has shown us that quantities under 2.5 litres (which is roughly 5% of the entire fuel tank volume) is quite often able to be adequately diluted by means of wholly topping up the tank with the appropriate fuel.
      It's rather rare to find a car suffering from issues because of below 5% incorrect fuel contamination. Keep in mind that it is rare - in no way impossible to find. You can get certain vehicles that will not stand any level of fuel contamination at all.
    2. Somewhere between 2.5 and 5 litres of Diesel in the Mini (from 5 to 10%) is a 50/50 scenario. Our expertise demonstrates that as many drivers get away with it as all those who break down. Whenever deciding whether or not to risk it and just simply fill it up remember that it is much like wagering it all on black - you have got a 50/50 chance of it working.
    3. Anything above 5 litres of Diesel in your Petrol Cooper must as soon as possible be drained out seeing that your probability of succeeding with this quantity of contamination is undoubtedly below one in fifty - really long odds.
  2. Put Diesel in a Petrol Mini and drove it: Have you detected any kind of performance troubles since putting the incorrect fuel in the Cooper? If so, have it drained regardless of the volume of Diesel or the contamination percentage. Continuing to drive driving a car that is already beginning to suffer the consequences of fuel contamination will only cause more and more damage being caused to the fuel system.
  3. Would you like assurance?
    Simply get it removed. No matter the contamination percentage, there is inevitably some extent of danger caused by driving a Petrol engine on fuel contaminated with the incorrect fuel. Probable implications of driving a vehicle on the wrong fuel include things like the motor not starting, running lumpy, loss of power, degradation of the high-pressure pump, damaged or blocked injectors, and the like. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you recognise any of them then stop 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.
