BMW Fuel Drain


Filling Diesel in a Petrol BMW is a very common mistake. And exactly what you need to do about it is dependent upon an assortment of things. If you want to find out what you should do to fix it then please read on.
Listed here are the key factors to be aware of when deciding on whether to have the car drained:

  1. How much Diesel did you put in to the BMW, keeping in mind that the fuel capacity of the BMW 1 M is usually roughly 53 litres?
    1. Hardly any Diesel, as little as 2.65 litres of Diesel in a Petrol 1 M will usually not necessarily be a massive problem. Experience has proven to us that quantities under 2.65 litres (which is 5% of the overall fuel tank capacity) is generally able to be completely diluted by totally filling up the rest of the tank with Petrol.
      It is pretty uncommon to find a vehicle suffering from issues with less than 5% wrong fuel contamination. Remember that it's infrequently found - in no way impossible to find. There are a few automobiles that don't endure any amount of contamination whatsoever.
    2. Between 2.65 and 5.3 litres of Diesel in the BMW (from 5 to 10%) is a 50/50 scenario. Our practical experience has demonstrated that as many people get away with it as all those who break down. When deciding on whether to risk it and basically top it up recognise that it is just like wagering all of it on black - you have a 50/50 possibility of it working out.
    3. Anything above 5.3 litres of Diesel in a Petrol 1 M ought to promptly be drained seeing that your probability of driving with this amount of contamination is certainly below one in 50 - really big odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any kind of performance problems after putting the bad fuel in your 1 M? In that case, get it removed no matter the amount of Diesel or even the contamination ratio. Continuing to run running a vehicle that is already beginning to suffer the effects of fuel contamination will definitely end up in increasing amounts of damage affecting your fuel system.
  3. Do you want security?
    Then simply just get it removed. Regardless of contamination ratio, there is invariably a certain level of threat linked with running a Petrol vehicle on fuel contaminated with the wrong fuel. Likely outcomes of driving a vehicle on the wrong fuel include things like the engine refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn out or bunged injectors, and the like. These are several of the most typical Diesel in Petrol symptoms, and if you notice any of them stop and have it drained right now.

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.
