BMW Fuel Drain


Filling Diesel in a Petrol BMW is a very common problem. And its solution is dependent upon an assortment of factors. In case you would like to know what you have to do to sort it out then continue reading.
Listed here are the main variables to take into consideration whenever figuring out whether or not to get the car drained:

  1. What level of Diesel have you put in to the BMW, considering that the fuel tank capacity of your BMW ActiveHybrid 7 is normally roughly 80 litres?
    1. A modest amount of Diesel, less than 4 litres of Diesel in a Petrol ActiveHybrid 7 will in most cases not be a big problem. Experience has demonstrated to us that an amount less than 4 litres (which is almost 5% of the overall fuel tank volume) is often capable of being completely diluted by thoroughly topping up the rest of the tank with the correct fuel.
      It is highly unusual to come across a car or truck having issues due to less than 5% incorrect fuel contamination. Bear in mind that it is unusual - definitely not impossible to find. There are actually some cars that won't endure any amount of fuel contamination in the slightest.
    2. Anywhere between 4 and 8 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 condition. Our working experience has revealed that as many motorists get away with this as those people who break down. When deciding on whether to risk it and simply fill it up consider that it is just like gambling your car on black - you've got a 50/50 chance of it being ok.
    3. Anything over 8 litres of Diesel in a Petrol ActiveHybrid 7 must straightaway be drained out as your likelihood of driving with that level of contamination is almost certainly below one in fifty - truly long odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you observed any performance concerns since putting the incorrect fuel in the ActiveHybrid 7? If you have, get it emptied regardless of the volume of Diesel or even the contamination percentage. Continuing to drive driving an automobile that is beginning to suffer the consequences of wrong fuel contamination will definitely end up in more and more harm being done to the fuel system.
  3. Are you looking for reassurance?
    In that case get it removed. Regardless of contamination percentage, there is always a certain level of risk resulting from running a Petrol motor on Petrol contaminated with the incorrect fuel. Probable implications of driving on the incorrect fuel include things like the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn or bunged injectors, etc. These are several of the commonest Diesel in Petrol signs or symptoms, and if you observe any of them 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.
