BMW Fuel Drain


Putting Diesel in a Petrol BMW is a fairly typical mistake. And exactly what you need to do about it varies according to a few things. In case you want to know what you must do about this then read on.
Listed here the most crucial variables to be aware of when determining whether to get a fuel drain:

  1. What amount of Diesel have you put into the BMW, bearing in mind that the fuel tank capacity of the BMW ActiveHybrid 5 is in most cases about 70 litres?
    1. A modest quantity of Diesel, something like 3.5 litres of Diesel in a Petrol ActiveHybrid 5 will typically not necessarily be a massive problem. Experience has proven to us that quantities under 3.5 litres (5% of the fuel tank volume) is usually capable of being adequately diluted simply by entirely filling up the tank with the correct fuel.
      It's relatively rare to find a car having problems because of below 5% wrong fuel contamination. Bear in mind that it is uncommon - certainly not impossible to encounter. There are actually a few vehicles that won't stand any degree of contamination whatsoever.
    2. In between 3.5 and 7 litres of Diesel in the BMW (from 5 to 10%) is more of a 50/50 condition. Our practical experience demonstrates that as many drivers get away with it as all those who don't. Whenever you are figuring out whether or not to risk it and just simply fill it up remember that it is exactly like betting your car on black - you have got a 50/50 possibility of it working.
    3. Anything more than 7 litres of Diesel in your Petrol ActiveHybrid 5 must promptly be drained seeing as your probability of getting away with that level of contamination is almost certainly below one in 50 - seriously huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you noticed any performance difficulties since putting the incorrect fuel in the ActiveHybrid 5? If so, have it emptied irrespective of the amount of Diesel or even the contamination percentage. Still driving a car that is now beginning to suffer the consequences of wrong fuel contamination will just bring about increasing amounts of damage affecting your fuel system components.
  3. Do you need reassurance?
    Then simply just get it drained. Regardless of contamination ratio, there is always some amount of threat connected to operating a Petrol motor on fuel contaminated with Diesel. Possible implications of driving on the incorrect fuel can include the engine refusing to start, running unevenly, losing power, degradation of the high-pressure pump, worn out or bunged injectors, and so on. These are a few of the most common Diesel in Petrol symptoms, and in the event that you detect any of them then stop and have it removed asap.

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.
