BMW Fuel Drain


Filling Petrol in a Diesel BMW is a fairly typical mistake. And what you want to do about it is dependent upon an assortment of things. If you want to find out what you have to do about this then keep reading.
Listed here are the key variables to to consider whenever figuring out whether or not to have a fuel drain:

  1. Exactly how much Petrol did you put in to the BMW, taking into account that the fuel capacity of the BMW 330xd is probably roughly 63 litres?
    1. A small quantity of Petrol, as little as 3.15 litres of Petrol in a Diesel 330xd will in most situations not be a major problem. Experience has demonstrated to us that quantities under 3.15 litres (which is approximately 5% of the whole fuel tank volume) is generally capable of being adequately diluted simply by wholly topping up the tank with Diesel.
      It's relatively uncommon to find a motor vehicle going through issues with under 5% wrong fuel contamination. Remember that it is very infrequently found - definitely not impossible to find. There are actually a number of automobiles that don't endure any level of fuel contamination whatsoever.
    2. Anywhere between 3.15 and 6.3 litres of Petrol in the BMW (from 5 to 10%) is a 50/50 condition. Our practical experience has shown that as many drivers get away with it as those who break down. Any time you are deciding on whether or not to risk it and basically fill it up remember that it is very much like wagering your car on black - you have a 50/50 possibility of it working.
    3. Anything in excess of 6.3 litres of Petrol in your Diesel 330xd must straight away be removed seeing that your probability of succeeding with that quantity of contamination is in all likelihood below one in 50 - really huge odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you noticed any kind of performance problems since putting the wrong fuel in your 330xd? In that case, get it drained regardless of the quantity of Petrol or even the contamination percentage. Continuing to run running a motor vehicle that is currently starting to suffer from the consequences of wrong fuel contamination will typically lead to more and more damage being caused to your fuel system.
  3. Do you need reassurance?
    Simply get it drained. Regardless of contamination ratio, there is inevitably some amount of danger affiliated with driving a Diesel vehicle on fuel contaminated with Petrol. Probable implications of driving on the incorrect fuel include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are a few of the most typical Petrol in Diesel signs or symptoms, and should you observe any of them then stop and get it drained immediately.

Petrol in Diesel FAQs

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?


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?


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?


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 Diesel 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.
