BMW Fuel Drain

ABOUT

Putting Petrol in a Diesel BMW is a fairly typical mistake to make. And its remedy varies according to a few factors. In the event that you would like to know what you should do to fix it then stay with me.
Let us discuss the most important variables to be aware of whenever choosing whether or not to get it drained:

  1. What level of Petrol have you put in to the BMW, considering that the fuel capacity of the BMW 118d is usually around 50 litres?
    1. A modest amount of Petrol, as little as 2.5 litres of Petrol in a Diesel 118d will quite often not be a huge problem. Experience has taught us that an amount less than 2.5 litres (which is about 5% of the fuel tank) is very often capable of being sufficiently diluted through totally filling the remainder of the tank with the appropriate fuel.
      It's pretty rare to come across a vehicle having difficulties with less than 5% incorrect fuel contamination. Keep in mind that it's infrequent - definitely not impossible to encounter. There are certain automobiles that won't stand any degree of fuel contamination at all.
    2. Anywhere between 2.5 and 5 litres of Petrol in the BMW (5 to 10%) is really a 50/50 scenario. Our expertise has confirmed that as many drivers get away with it as those who don't. Whenever you are deciding on whether to risk it and simply fill it up recognise that it is the same as gambling all of it on black - you have got a 50/50 chance of it being ok.
    3. Anything over 5 litres of Petrol in your Diesel 118d should really promptly be removed as your probability of getting away with that level of contamination is undoubtedly below one in 50 - extremely big odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you detected any kind of performance issues after putting the wrong fuel in the 118d? If you have, get it emptied irrespective of the volume of Petrol or the contamination percentage. Continually running a car that is now beginning to suffer the effects of fuel contamination will typically result in progressively more harm being done to your fuel system components.
  3. Do you want reassurance?
    In that case get it drained. Regardless of contamination percentage, there is invariably some amount of risk caused by running a Diesel motor on fuel contaminated with the wrong fuel. Likely final outcomes of driving on the incorrect fuel include the engine not starting, running unevenly, lack of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are several of the most typical Petrol in Diesel warning signs, and in the event that you notice any of them then cease driving and get it drained immediately.

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?

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

Will driving a Diesel car on Petrol cause damage to it?

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 Petrol can I get away with in a Diesel 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 Diesel 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.
