BMW Fuel Drain


Putting Diesel in a Petrol BMW is a usual mistake. And what you want to do about it hinges on a few things. Assuming you want to know what you have to do to sort it out then continue reading.
Right here are the key factors to take into account when making a decision whether or not to have it drained:

  1. What level of Diesel have you put in to the BMW, keeping in mind that the fuel capacity of the BMW x3 is most likely around 67 litres?
    1. A small amount of Diesel, as little as 3.35 litres of Diesel in a Petrol x3 will in most situations not really be a massive problem. Experience has taught us that an amount less than 3.35 litres (which is 5% of the fuel tank) is frequently able to be adequately diluted through entirely topping up the remainder of the tank with the right fuel.
      It's very uncommon to encounter an automobile having difficulties because of under 5% incorrect fuel contamination. Remember that it's rare - definitely not impossible to find. You will discover a number of cars that will not endure any amount of fuel contamination at all.
    2. Somewhere between 3.35 and 6.7 litres of Diesel in the BMW (5 to 10%) is really a 50/50 situation. Our practical experience demonstrates that as many people get away with it as all those who break down. When deciding upon whether or not to chance it and basically top it up recognise that it is the same thing as wagering everything on black - you've got a 50/50 chance of it working out.
    3. Anything over 6.7 litres of Diesel in your Petrol x3 should really straightaway be drained as your probability of getting away with that quantity of contamination is very likely less than one in 50 - truly big odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any kind of performance problems ever since putting the bad fuel in the x3? If that's the case, have it emptied irrespective of the amount of Diesel or the contamination percentage. Proceeding to drive driving an automobile that is already starting to suffer the effects of wrong fuel contamination can only lead to even more harm affecting the fuel system.
  3. Are you looking for assurance?
    You should get it drained. Regardless of the contamination ratio, there is inevitably a certain level of threat affiliated with running a Petrol engine on Petrol contaminated with the wrong fuel. Probable consequences of driving a vehicle on the incorrect fuel include the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the commonest Diesel in Petrol signs and symptoms, and should you detect any of them then stop driving and get 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.
