BMW Fuel Drain


Filling up with Petrol in a Diesel BMW is a regular mistake to make. And what you should do about it depends upon a number of things. In case you would like to find out what you have to do to sort it out then keep on reading.
Right here are the most important variables to consider whenever deciding whether to get a fuel drain:

  1. How much Petrol did you put in to the BMW, considering that the fuel capacity of your BMW 750Ld xDrive is usually roughly 80 litres?
    1. A tiny quantity of Petrol, as little as 4 litres of Petrol in a Diesel 750Ld xDrive will most of the time not necessarily be a significant problem. Experience has proven to us that anything under 4 litres (which is about 5% of the entire fuel tank capacity) is generally able to be adequately diluted by totally filling the rest of the tank with Diesel.
      It is quite rare to encounter an automobile suffering from issues due to lower than 5% wrong fuel contamination. Bear in mind that it's uncommon - not impossible to encounter. You will discover certain cars that don't stand any level of fuel contamination at all.
    2. Between 4 and 8 litres of Petrol in the BMW (5 to 10%) is really a 50/50 situation. Our working experience has demonstrated that as many people get away with this as those people who don't. Any time you're trying to decide whether to risk it and just fill it up consider that it is much like betting your car on black - you have got a 50/50 chance of it working.
    3. Anything above 8 litres of Petrol in a Diesel 750Ld xDrive should straight away be drained because your likelihood of driving with this quantity of contamination is more than likely lower than one in fifty - seriously long odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you seen any kind of performance concerns since putting the incorrect fuel in your 750Ld xDrive? If you have, get it removed no matter the volume of Petrol or the contamination ratio. Continually running an automobile that is already starting to suffer from the effect of fuel contamination will just result in more damage affecting the fuel system components.
  3. Would you like security?
    Simply get it drained. Regardless of contamination ratio, there is always a certain level of threat caused by driving a Diesel motor on Diesel contaminated with Petrol. Likely final outcomes of driving on the wrong fuel include the motor refusing to start, running unevenly, losing power, degradation of the high-pressure pump, damaged or clogged injectors, and the like. These are some of the most frequently seen Petrol in Diesel signs and symptoms, and should you detect any of them then cease driving and have it drained right away.

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.
