BMW Fuel Drain

ABOUT

Putting Diesel in a Petrol BMW is a very common mistake to make. And what you want to do about it will depend on an assortment of factors. If perhaps you would like to know what to do to sort it out then keep on reading.
Listed here are the most important variables to take into consideration when figuring out whether or not to get a fuel drain:

  1. What amount of Diesel did you put in to the BMW, bearing in mind that the fuel capacity of your BMW 730i is most likely roughly 88 litres?
    1. A tiny amount of Diesel, as little as 4.4 litres of Diesel in a Petrol 730i will most of the time not be a massive problem. Experience has proven to us that an amount less than 4.4 litres (close to 5% of the whole fuel tank volume) is quite often capable of being sufficiently diluted through totally filling up the tank with the right fuel.
      It is highly uncommon to find a car having problems with under 5% incorrect fuel contamination. Keep in mind it is uncommon - in no way impossible to find. There are actually a number of cars that will not endure any quantity of fuel contamination whatsoever.
    2. In between 4.4 and 8.8 litres of Diesel in the BMW (from 5 to 10%) is really a 50/50 situation. Our working experience has demonstrated that as many drivers get away with this as those who break down. Whenever deciding whether or not to risk it and just simply fill it up bear in mind that it is very much like betting all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything over 8.8 litres of Diesel in a Petrol 730i really should straight away be drained out seeing as your probability of driving with that amount of contamination is in all likelihood below one in fifty - genuinely long odds.
  2. Put some Diesel in a Petrol BMW and drove it: Have you spotted any kind of performance problems after putting the incorrect fuel in the 730i? If you have, get it removed irrespective of the quantity of Diesel or even the contamination ratio. Continually driving a vehicle that is beginning to suffer the effect of fuel contamination will probably definitely be responsible for increasing amounts of damage being caused to your fuel system parts.
  3. Are you interested in peace of mind?
    Then simply just get it removed. Whatever the contamination ratio, there is always a certain level of risk connected with running a Petrol vehicle on fuel contaminated with Diesel. Possible final outcomes of driving a vehicle on the wrong fuel include things like the engine not starting, running lumpy, reduced power, wearing of the high-pressure pump, worn or blocked injectors, and so on. These are some of the most common Diesel in Petrol signs or symptoms, and if you recognise any of them stop driving and get it drained as soon as possible.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
