BMW Fuel Drain


Filling Diesel in a Petrol BMW is a regular error. And what you want to do about it will depend on a few things. In the event that you would like to find out what to do to fix it then keep reading.
Right here are the most important variables to be aware of whenever determining whether to have a fuel drain:

  1. What level of Diesel did you put in to the BMW, considering that the fuel tank capacity of the BMW M5 Touring is normally about 70 litres?
    1. A modest quantity of Diesel, as little as 3.5 litres of Diesel in a Petrol M5 Touring will quite often not really be a huge problem. Experience has demonstrated to us that anything under 3.5 litres (5% of the fuel tank) is generally capable of being adequately diluted through totally filling up the remainder of the tank with Petrol.
      It's relatively unusual to encounter a motor vehicle suffering from problems with lower than 5% wrong fuel contamination. Do not forget that it's infrequently found - certainly not impossible to find. You will discover a few automobiles that won't stand any degree of contamination in the slightest.
    2. In between 3.5 and 7 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 situation. Our expertise has shown that as many motorists get away with it as all those who break down. Any time you are deciding whether to chance it and basically top it up bear in mind that it is very much like gambling everything on black - you have a 50/50 chance of it working out.
    3. Anything more than 7 litres of Diesel in your Petrol M5 Touring should promptly be drained as your likelihood of driving with this quantity of contamination is probably lower than one in fifty - extremely long odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any performance concerns after putting the bad fuel in your M5 Touring? If you have, get it drained irrespective of the quantity of Diesel or even the contamination percentage. Continually running a car that is starting to suffer from the consequences of wrong fuel contamination can just bring about more harm being caused to your fuel system.
  3. Are you looking for security?
    You should get it emptied. Regardless of contamination percentage, there is always a certain level of risk affiliated with running a Petrol engine on Petrol contaminated with Diesel. Likely final outcomes of driving on the wrong fuel normally include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, damaged or blocked injectors, and so forth. These are several of the most typical Diesel in Petrol warning signs, and should you detect any of them stop and get it removed immediately.

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.
