BMW Fuel Drain


Filling Diesel in a Petrol BMW is a usual error. And what you should do about it hinges on a few things. In case you want to know what you ought to do to sort it out then read on.
Listed here are the most important variables to take into consideration when determining whether to get a fuel drain:

  1. What amount of Diesel did you put in to the BMW, keeping in mind that the fuel capacity of your BMW M6 Coupe is usually around 70 litres?
    1. A small amount of Diesel, something like 3.5 litres of Diesel in a Petrol M6 Coupe will quite often not necessarily be a significant problem. Experience has demonstrated to us that an amount less than 3.5 litres (roughly 5% of the whole fuel tank volume) is oftentimes capable of being completely diluted through completely filling the tank with the right fuel.
      It's pretty unusual to come across a car having problems because of lower than 5% wrong fuel contamination. Remember that it's uncommon - in no way impossible to find. You can get some motor vehicles that won't stand any quantity of fuel contamination whatsoever.
    2. Between 3.5 and 7 litres of Diesel in the BMW (5 to 10%) is a 50/50 scenario. Our experience has revealed that as many motorists get away with this as those who don't. Whenever you are figuring out whether or not to risk it and basically top it up recognise that it is just like betting your car on black - you have got a 50/50 chance of it being ok.
    3. Anything above 7 litres of Diesel in a Petrol M6 Coupe ought to immediately be drained out since your probability of driving with that quantity of contamination is almost certainly below one in 50 - seriously huge odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you observed any performance difficulties since putting the bad fuel in your M6 Coupe? If you have, have it removed irrespective of the quantity of Diesel or even the contamination percentage. Continuing to drive running a motor vehicle that is currently starting to suffer the consequences of fuel contamination can only end up in increasing amounts of harm being done to the fuel system components.
  3. Are you looking for assurance?
    Simply get it emptied. Regardless of contamination percentage, there is always some amount of threat connected with operating a Petrol motor on Petrol contaminated with Diesel. Likely consequences of driving on the incorrect fuel can include the engine not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn out or bunged injectors, and so forth. These are a few of the most common Diesel in Petrol symptoms, and in the event that you notice any of them stop driving and get it drained 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.
