Mini Fuel Drain


Filling up with Diesel in a Petrol Mini is a well-known mistake. And its remedy is based on a few factors. Assuming you want to find out what you must do about this then continue reading.
Listed here are the main factors to keep in mind when deciding whether or not to get it drained:

  1. What amount of Diesel did you put in the Mini, considering that the fuel tank capacity of your Mini Cooper Clubman is most likely around 40 litres?
    1. A modest amount of Diesel, less than 2 litres of Diesel in a Petrol Cooper Clubman will normally not necessarily be a major problem. Experience has shown us that quantities under 2 litres (roughly 5% of the total fuel tank) is very often capable of being sufficiently diluted by means of wholly topping up the tank with the correct fuel.
      It's rather uncommon to encounter a vehicle experiencing problems because of under 5% wrong fuel contamination. Be aware that it is infrequently found - definitely not impossible to encounter. There are certain motor vehicles that won't endure any degree of contamination in the slightest.
    2. Between 2 and 4 litres of Diesel in the Mini (from 5 to 10%) is more of a 50/50 situation. Our expertise has proven that as many motorists get away with this as those people who break down. Whenever deciding on whether or not to chance it and just simply fill it up remember that it is much like wagering it all on black - you have a 50/50 possibility of it working out.
    3. Anything more than 4 litres of Diesel in a Petrol Cooper Clubman ought to straightaway be drained out seeing as your likelihood of succeeding with this quantity of contamination is in all likelihood less than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Mini and drove it: Have you noted any performance difficulties since putting the wrong fuel in your Cooper Clubman? If that's the case, have it emptied irrespective of the quantity of Diesel or the contamination ratio. Proceeding to drive running a motor vehicle that is beginning to suffer the effect of fuel contamination will probably typically end up in even more harm being done to the fuel system components.
  3. Do you want security?
    You should get it removed. Regardless of the contamination percentage, there is inevitably some extent of danger connected to operating a Petrol motor on fuel contaminated with Diesel. Probable outcomes of driving a vehicle on the wrong fuel can include the engine not starting, running unevenly, lack of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are some of the most common Diesel in Petrol signs or symptoms, and in the event that you observe any of them then stop and have it drained 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.
