BMW Fuel Drain


Putting Petrol in a Diesel BMW is a regular mistake. And exactly what you should do about it hinges on an assortment of factors. In case you would like to find out what you need to do about it then stay with me.
Right here are the main variables to consider when deciding whether to get it drained:

  1. What level of Petrol did you put into the BMW, keeping in mind that the fuel capacity of the BMW 320d is normally around 63 litres?
    1. A modest quantity of Petrol, less than 3.15 litres of Petrol in a Diesel 320d will more often than not not be a big problem. Experience has proven to us that anything under 3.15 litres (5% of the overall fuel tank) is very often capable of being sufficiently diluted through totally filling the remainder of the tank with the correct fuel.
      It's extremely rare to come across an automobile suffering from difficulties with below 5% wrong fuel contamination. Please remember it is unusual - in no way impossible to encounter. There are a few vehicles that will not stand any amount of fuel contamination whatsoever.
    2. Anywhere between 3.15 and 6.3 litres of Petrol in the BMW (5 to 10%) is more of a 50/50 condition. Our practical experience demonstrates that as many motorists get away with this as those people who don't. Any time you are deciding whether to risk it and just simply top it up bear in mind that it is the same as gambling your car on black - you've got a 50/50 chance of it working out.
    3. Anything more than 6.3 litres of Petrol in your Diesel 320d ought to promptly be removed as your likelihood of driving with that amount of contamination is in all likelihood lower than one in fifty - truly big odds.
  2. Put some Petrol in a Diesel BMW and drove it: Have you noticed any kind of performance issues ever since putting the incorrect fuel in your 320d? If you have, have it drained no matter the amount of Petrol or even the contamination ratio. Still running a motor vehicle that is starting to suffer from the consequences of wrong fuel contamination will probably just end up in more damage affecting your fuel system.
  3. Are you looking for reassurance?
    In that case get it drained. Regardless of contamination percentage, there is inevitably some extent of risk connected with operating a Diesel engine on fuel contaminated with Petrol. Possible results of driving on the incorrect fuel normally include the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, worn out or blocked injectors, and so on. These are some of the most common Petrol in Diesel signs or symptoms, and if you detect any of them cease driving and get it drained right away.

Petrol in Diesel Questions

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.
