BMW Fuel Drain


Filling up with Diesel in a Petrol BMW is a fairly typical mistake to make. And its solution depends on a variety of factors. If perhaps you want to find out what it is best to do about this then stay with me.
Right here are the key factors to consider when choosing whether or not to have your car drained:

  1. How much Diesel did you put in the BMW, considering that the fuel tank capacity of your BMW 325Ci is normally about 63 litres?
    1. A tiny amount of Diesel, less than 3.15 litres of Diesel in a Petrol 325Ci will generally not necessarily be a massive problem. Experience has demonstrated to us that quantities less than 3.15 litres (close to 5% of the total fuel tank capacity) is oftentimes capable of being sufficiently diluted simply by thoroughly topping up the tank with the correct fuel.
      It is extremely rare to encounter a car or truck going through problems due to below 5% wrong fuel contamination. Please remember it is very rare - definitely not impossible to find. There are actually certain cars that don't stand any degree of contamination whatsoever.
    2. Somewhere between 3.15 and 6.3 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 scenario. Our experience has revealed that as many people get away with this as those who don't. When you are deciding on whether to risk it and simply top it up consider that it is much like wagering everything on black - you will have a 50/50 chance of it being ok.
    3. Anything over 6.3 litres of Diesel in your Petrol 325Ci should really right away be removed as your likelihood of succeeding with this level of contamination is almost certainly lower than one in 50 - extremely long odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you observed any kind of performance concerns ever since putting the incorrect fuel in your 325Ci? If you have, have it drained no matter the quantity of Diesel or even the contamination percentage. Continually running a vehicle that is beginning to suffer from the effect of wrong fuel contamination will definitely be responsible for increasing amounts of harm affecting the fuel system parts.
  3. Would you like reassurance?
    You should get it emptied. Regardless of the contamination percentage, there is always some degree of risk in connection with running a Petrol motor on fuel contaminated with the incorrect fuel. Probable outcomes of driving a vehicle on the incorrect fuel normally include the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, damaged or blocked injectors, etc. These are a few of the most typical Diesel in Petrol warning signs, and if you detect any of them cease driving and have it removed 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?


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.
