BMW Fuel Drain


Filling Diesel in a Petrol BMW is a regular error. And its remedy depends upon a variety of things. If you would like to find out what you have to do to fix it then read on.
Listed below are the key variables to take into consideration whenever making a decision whether to get your car drained:

  1. What amount of Diesel did you put in to the BMW, taking into consideration that the fuel capacity of the BMW 320Ci is in most cases around 63 litres?
    1. Hardly any Diesel, less than 3.15 litres of Diesel in a Petrol 320Ci will most of the time not necessarily be a significant problem. Experience has demonstrated to us that an amount less than 3.15 litres (which is close to 5% of the overall fuel tank capacity) is generally able to be sufficiently diluted by means of entirely filling the remainder of the tank with Petrol.
      It's relatively rare to encounter a car or truck suffering from problems because of lower than 5% incorrect fuel contamination. Bear in mind that it is infrequently found - certainly not impossible to encounter. There are some motor vehicles that won't stand any quantity of contamination whatsoever.
    2. Somewhere between 3.15 and 6.3 litres of Diesel in the BMW (from 5 to 10%) is more of a 50/50 situation. Our experience has shown us that as many motorists get away with this as all those who break down. Whenever figuring out whether to risk it and basically top it up consider that it is the same as wagering your car on black - you've got a 50/50 possibility of it working.
    3. Anything above 6.3 litres of Diesel in a Petrol 320Ci really should straight away be drained out seeing that your likelihood of driving with this level of contamination is probably lower than one in 50 - seriously huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any kind of performance issues as a result of putting the wrong fuel in the 320Ci? If you have, get it removed irrespective of the amount of Diesel or even the contamination percentage. Continually running a car that is currently starting to suffer from the effect of fuel contamination will just be responsible for progressively more damage affecting your fuel system components.
  3. Would you like reassurance?
    You should get it drained. Whatever the contamination ratio, there is always some extent of threat affiliated with running a Petrol vehicle on Petrol contaminated with the wrong fuel. Probable implications of driving a vehicle on the incorrect fuel normally include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are several of the commonest Diesel in Petrol symptoms, and in the event that you detect any of them then stop and get it drained asap.

Diesel in Petrol Questions

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.
