BMW Fuel Drain

ABOUT

Putting Diesel in a Petrol BMW is a fairly typical error. And its solution hinges on a number of factors. In the event that you would like to find out what you should do about it then read on.
Listed below are the key variables to think about whenever deciding on whether or not to have it drained:

  1. How much Diesel have you put in the BMW, bearing in mind that the fuel capacity of the BMW M135i is normally roughly 53 litres?
    1. A modest amount of Diesel, as little as 2.65 litres of Diesel in a Petrol M135i will normally not be a massive problem. Experience has taught us that an amount less than 2.65 litres (which is close to 5% of the overall fuel tank) is sometimes able to be completely diluted by completely filling up the rest of the tank with the right fuel.
      It is highly uncommon to encounter a vehicle experiencing problems because of below 5% wrong fuel contamination. Do not forget that it is very unusual - not impossible to encounter. There are actually some automobiles that don't endure any amount of fuel contamination at all.
    2. Anywhere between 2.65 and 5.3 litres of Diesel in the BMW (5 to 10%) is really a 50/50 scenario. Our experience has proven that as many people get away with it as those people who don't. Whenever deciding whether or not to risk it and basically fill it up consider that it is just like wagering it all on black - you will have a 50/50 possibility of it working.
    3. Anything more than 5.3 litres of Diesel in a Petrol M135i really should straight away be drained as your probability of getting away with that quantity of contamination is in all likelihood less than one in 50 - seriously big odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you noticed any kind of performance problems ever since putting the bad fuel in your M135i? If that's the case, get it removed regardless of the quantity of Diesel or even the contamination percentage. Still running a car that is beginning to suffer from the consequences of wrong fuel contamination can just end up in progressively more damage affecting the fuel system parts.
  3. Do you need security?
    Then simply just get it drained. Regardless of the contamination ratio, there is inevitably some extent of threat affiliated with running a Petrol engine on Petrol contaminated with Diesel. Possible final outcomes of driving a vehicle on the wrong fuel normally include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn out or blocked injectors, and so on. These are a few of the commonest Diesel in Petrol warning signs, and should you notice any of them stop and have it drained asap.

Diesel in Petrol FAQs

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?

Answer

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

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
