BMW Fuel Drain


Filling up with Diesel in a Petrol BMW is a regular mistake. And what you need to do about it is based on an assortment of factors. In case you want to know what you must do about it then stay with me.
Listed here are the most important factors to take into consideration whenever choosing whether or not to get a fuel drain:

  1. What amount of Diesel did you put into the BMW, taking into consideration that the fuel capacity of the BMW M6 is usually about 70 litres?
    1. A modest amount of Diesel, less than 3.5 litres of Diesel in a Petrol M6 will normally not necessarily be a big problem. Experience has demonstrated to us that anything less than 3.5 litres (which is about 5% of the entire fuel tank volume) is frequently capable of being adequately diluted by thoroughly topping up the rest of the tank with Petrol.
      It is rather rare to find an automobile going through difficulties due to less than 5% incorrect fuel contamination. Please remember it is very rare - not impossible to encounter. There are a few vehicles that will not endure any amount of fuel contamination whatsoever.
    2. Somewhere between 3.5 and 7 litres of Diesel in the BMW (5 to 10%) is a 50/50 situation. Our expertise has shown that as many people get away with this as those who don't. Any time you are trying to decide whether or not to chance it and just simply top it up recognise that it is the same thing as betting your car on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 7 litres of Diesel in your Petrol M6 really should straight away be drained seeing that your likelihood of driving with this amount of contamination is very likely lower than one in fifty - seriously long odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you detected any kind of performance problems after putting the bad fuel in the M6? In that case, get it drained regardless of the amount of Diesel or the contamination ratio. Still driving a vehicle that is currently beginning to suffer the consequences of wrong fuel contamination can likely be responsible for even more harm being caused to the fuel system components.
  3. Do you need assurance?
    In that case get it emptied. Regardless of contamination percentage, there is inevitably some extent of threat connected with running a Petrol engine on fuel contaminated with the wrong fuel. Probable results of driving on the incorrect fuel include things like the motor not starting, running unevenly, loss in power, wearing of the high-pressure pump, worn out or blocked injectors, and so on. These are a few of the most common Diesel in Petrol symptoms, and if you recognise any of them then stop and get it removed right away.

Diesel in Petrol Questions

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.
