BMW Fuel Drain


Putting Petrol in a Diesel BMW is a regular mistake to make. And exactly what you have to do about it will depend on an assortment of things. In the event that you want to know what you must do about this then keep reading.
Right here are the most important factors to take into account whenever making a decision whether to have the car drained:

  1. What amount of Petrol did you put in to the BMW, taking into account that the fuel capacity of the BMW 114d is probably around 52 litres?
    1. A small quantity of Petrol, as little as 2.6 litres of Petrol in a Diesel 114d will normally not necessarily be a huge problem. Experience has demonstrated to us that an amount under 2.6 litres (which is approximately 5% of the entire fuel tank volume) is very often able to be adequately diluted by means of completely topping the rest of the tank with the appropriate fuel.
      It's extremely uncommon to come across an automobile suffering from difficulties with less than 5% incorrect fuel contamination. Do not forget that it is infrequent - definitely not impossible to encounter. You can get certain cars that don't stand any quantity of fuel contamination in the slightest.
    2. Somewhere between 2.6 and 5.2 litres of Petrol in the BMW (from 5 to 10%) is really a 50/50 situation. Our experience has demonstrated that as many drivers get away with it as those people who don't. Whenever deciding whether to risk it and just simply fill it up remember that it is just like betting it all on black - you've got a 50/50 chance of it working out.
    3. Anything over 5.2 litres of Petrol in your Diesel 114d really should right away be removed since your probability of getting away with this level of contamination is very likely less than one in fifty - truly big odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you observed any performance problems as a result of putting the wrong fuel in your 114d? In that case, get it emptied regardless of the quantity of Petrol or the contamination ratio. Proceeding to drive running a motor vehicle that is now beginning to suffer the consequences of wrong fuel contamination can likely lead to even more damage affecting your fuel system parts.
  3. Are you interested in security?
    In that case get it removed. Whatever the contamination ratio, there is invariably some extent of danger linked with driving a Diesel engine on fuel contaminated with the wrong fuel. Probable final outcomes of driving a vehicle on the wrong fuel can include the motor not starting, running lumpy, loss in power, wearing of the high-pressure pump, worn out or blocked injectors, and so on. These are several of the most common Petrol in Diesel signs and symptoms, and in the event that you recognise any of them stop and have it removed right now.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
