BMW Fuel Drain


Filling Petrol in a Diesel BMW is a fairly typical problem. And its solution is based on a number of things. In case you would like to know what you ought to do about it then please read on.
Listed below are the main variables to think about when deciding whether or not to have a fuel drain:

  1. How much Petrol have you put in the BMW, taking into consideration that the fuel tank capacity of your BMW M550d xDrive Touring is normally about 70 litres?
    1. A modest amount of Petrol, less than 3.5 litres of Petrol in a Diesel M550d xDrive Touring will usually not be a significant problem. Experience has proven to us that anything less than 3.5 litres (roughly 5% of the entire fuel tank volume) is very often able to be sufficiently diluted simply by wholly filling the remainder of the tank with the appropriate fuel.
      It is very rare to find an automobile experiencing problems with lower than 5% incorrect fuel contamination. Keep in mind it is infrequent - certainly not impossible to find. There are actually a number of automobiles that will not stand any amount of fuel contamination whatsoever.
    2. Anywhere between 3.5 and 7 litres of Petrol in the BMW (from 5 to 10%) is more of a 50/50 condition. Our expertise has confirmed that as many drivers get away with this as those people who don't. When you are deciding on whether to chance it and basically top it up recognise that it is much like betting everything on black - you will have a 50/50 possibility of it being ok.
    3. Anything above 7 litres of Petrol in a Diesel M550d xDrive Touring ought to straight away be removed seeing as your probability of driving with that amount of contamination is probably lower than one in 50 - seriously huge odds.
  2. Put some Petrol in a Diesel BMW and drove it: Have you spotted any kind of performance troubles since putting the wrong fuel in your M550d xDrive Touring? If that's the case, get it drained no matter the volume of Petrol or the contamination percentage. Proceeding to drive running a motor vehicle that is starting to suffer the effects of fuel contamination will likely lead to progressively more harm being caused to your fuel system parts.
  3. Are you interested in reassurance?
    Then simply just get it drained. Regardless of the contamination percentage, there is inevitably some degree of threat affiliated with operating a Diesel motor on fuel contaminated with Petrol. Probable results of driving on the incorrect fuel normally include the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or bunged injectors, and so forth. These are a few of the commonest Petrol in Diesel signs or symptoms, and in the event that you recognise any of them then stop driving and get it drained right now.

Petrol in Diesel FAQs

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.
