BMW Fuel Drain


Filling Diesel in a Petrol BMW is a regularly occurring error. And what you should do about it will depend on a variety of things. In the event that you want to find out what you have to do to sort it out then keep on reading.
Right here are the main factors to consider whenever figuring out whether or not to have the car drained:

  1. What level of Diesel have you put in to the BMW, taking into account that the fuel tank capacity of the BMW 316i is normally about 65 litres?
    1. Hardly any Diesel, less than 3.25 litres of Diesel in a Petrol 316i will usually not be a significant problem. Experience has shown us that anything less than 3.25 litres (almost 5% of the fuel tank volume) is in many instances capable of being adequately diluted by entirely topping the tank with the right fuel.
      It is relatively uncommon to come across a car or truck suffering from difficulties with under 5% incorrect fuel contamination. Be aware that it is very infrequently found - definitely not impossible to find. You will discover a number of vehicles that don't stand any quantity of contamination at all.
    2. Somewhere between 3.25 and 6.5 litres of Diesel in the BMW (5 to 10%) is more of a 50/50 scenario. Our experience has demonstrated that as many drivers get away with this as those people who break down. When deciding whether to chance it and just simply fill it up recognise that it is just like gambling your car on black - you've got a 50/50 chance of it working.
    3. Anything more than 6.5 litres of Diesel in a Petrol 316i ought to as soon as possible be drained out as your likelihood of getting away with this level of contamination is almost certainly lower than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you detected any performance issues since putting the bad fuel in the 316i? In that case, have it removed regardless of the volume of Diesel or the contamination percentage. Continuing to drive driving a car that is beginning to suffer the effect of wrong fuel contamination can only lead to progressively more damage affecting the fuel system components.
  3. Are you looking for peace of mind?
    In that case get it removed. Regardless of the contamination ratio, there is inevitably a certain level of risk resulting from driving a Petrol vehicle on fuel contaminated with Diesel. Possible implications of driving a car on the incorrect fuel include things like the engine refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are some of the most typical Diesel in Petrol symptoms, and if you recognise any of them stop and have it drained immediately.

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.
