BMW Fuel Drain


Filling up with Diesel in a Petrol BMW is a very common problem. And exactly what you want to do about it hinges on several different factors. In the event that you want to find out what it is best to do to sort it out then keep on reading.
Listed below are the most important variables to keep in mind whenever deciding on whether or not to have the car drained:

  1. What amount of Diesel have you put in the BMW, bearing in mind that the fuel capacity of the BMW 130i is normally around 53 litres?
    1. A modest quantity of Diesel, as little as 2.65 litres of Diesel in a Petrol 130i will most of the time not really be a huge problem. Experience has demonstrated to us that quantities less than 2.65 litres (almost 5% of the overall fuel tank capacity) is sometimes capable of being sufficiently diluted simply by wholly filling up the rest of the tank with Petrol.
      It is rather uncommon to encounter an automobile having issues with under 5% wrong fuel contamination. Keep in mind it is uncommon - not impossible to find. You will discover a number of vehicles that will not stand any degree of contamination whatsoever.
    2. Somewhere between 2.65 and 5.3 litres of Diesel in the BMW (5 to 10%) is a 50/50 condition. Our experience has revealed that as many people get away with it as those who break down. When figuring out whether or not to risk it and just simply top it up bear in mind that it is the same as betting all of it on black - you will have a 50/50 chance of it working out.
    3. Anything more than 5.3 litres of Diesel in your Petrol 130i ought to immediately be drained out because your likelihood of driving with that level of contamination is more than likely below one in 50 - extremely huge odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you seen any performance concerns since putting the incorrect fuel in the 130i? If you have, have it drained regardless of the amount of Diesel or even the contamination ratio. Still running an automobile that is now beginning to suffer from the effects of fuel contamination will likely result in more and more harm being done to the fuel system components.
  3. Are you interested in security?
    In that case get it drained. Whatever the contamination percentage, there is invariably some extent of risk linked with running a Petrol engine on fuel contaminated with Diesel. Likely outcomes of driving on the incorrect fuel include the motor not starting, running lumpy, loss in power, wearing of the high-pressure pump, worn out or clogged injectors, etc. These are a few of the most typical Diesel in Petrol symptoms, and should you detect any of them stop driving and get it removed right away.

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.
