BMW Fuel Drain

ABOUT

Filling Petrol in a Diesel BMW is a common problem. And exactly what you have to do about it is dependent upon several different things. If perhaps you want to find out what you have to do about this then continue reading.
Let us discuss the key variables to to consider when deciding whether to have a fuel drain:

  1. What level of Petrol have you put in the BMW, bearing in mind that the fuel tank capacity of the BMW 730d is usually around 85 litres?
    1. A small amount of Petrol, as little as 4.25 litres of Petrol in a Diesel 730d will typically not necessarily be a massive problem. Experience has taught us that anything less than 4.25 litres (which is 5% of the overall fuel tank capacity) is in many instances able to be sufficiently diluted by means of wholly filling the remainder of the tank with Diesel.
      It's very uncommon to come across a vehicle experiencing problems due to below 5% wrong fuel contamination. Remember that it is rare - definitely not impossible to encounter. You can get certain vehicles that won't endure any degree of contamination at all.
    2. Anywhere between 4.25 and 8.5 litres of Petrol in the BMW (5 to 10%) is really a 50/50 condition. Our practical experience has shown us that as many motorists get away with it as those people who break down. Whenever deciding whether to chance it and just simply top it up bear in mind that it is exactly like gambling all of it on black - you've got a 50/50 possibility of it working out.
    3. Anything more than 8.5 litres of Petrol in your Diesel 730d must right away be drained out since your probability of succeeding with this quantity of contamination is undoubtedly lower than one in 50 - truly huge odds.
  2. Put Petrol in a Diesel BMW and drove it: Have you observed any kind of performance problems as a result of putting the bad fuel in the 730d? If that's the case, get it emptied irrespective of the amount of Petrol or even the contamination ratio. Proceeding to drive running an automobile that is already beginning to suffer from the effect of fuel contamination will probably typically be responsible for more harm affecting the fuel system components.
  3. Are you interested in peace of mind?
    In that case get it emptied. Whatever the contamination percentage, there is inevitably some degree of threat connected to driving a Diesel engine on fuel contaminated with the incorrect fuel. Possible implications of driving on the wrong fuel include things like the motor refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn out or blocked injectors, and the like. These are a few of the most frequently seen Petrol in Diesel signs and symptoms, and if you observe any of them stop driving and get it removed right now.

Petrol in Diesel Questions

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?

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