BMW Fuel Drain

ABOUT

Filling up with Diesel in a Petrol BMW is a fairly typical error. And its remedy varies according to various things. In case you would like to know what you must do to sort it out then continue reading.
Here are the most important variables to to consider when figuring out whether to get the car drained:

  1. Exactly how much Diesel did you put in to the BMW, keeping in mind that the fuel capacity of the BMW Z4 is most likely about 55 litres?
    1. Hardly any Diesel, less than 2.75 litres of Diesel in a Petrol Z4 will normally not really be a big problem. Experience has taught us that anything less than 2.75 litres (about 5% of the fuel tank capacity) is very often able to be completely diluted by totally topping the tank with the right fuel.
      It's highly unusual to find a car going through problems with less than 5% incorrect fuel contamination. Keep in mind that it's unusual - in no way impossible to encounter. You will discover a number of cars that will not stand any degree of contamination whatsoever.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the BMW (from 5 to 10%) is a 50/50 scenario. Our expertise has confirmed that as many motorists get away with this as those who break down. When you are figuring out whether or not to chance it and basically top it up bear in mind that it is exactly like betting all of it on black - you will have a 50/50 possibility of it working out.
    3. Anything in excess of 5.5 litres of Diesel in your Petrol Z4 ought to immediately be drained out because your probability of getting away with this level of contamination is in all likelihood lower than one in fifty - genuinely huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you spotted any performance concerns after putting the bad fuel in your Z4? If so, get it removed no matter the amount of Diesel or the contamination percentage. Continuing to drive driving a vehicle that is starting to suffer from the consequences of wrong fuel contamination can likely cause more and more damage being done to the fuel system parts.
  3. Do you need reassurance?
    Then simply just get it removed. Regardless of contamination ratio, there is always a certain level of threat connected to driving a Petrol motor on Petrol contaminated with the wrong fuel. Likely results of driving a vehicle on the incorrect fuel normally include the engine not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are several of the commonest Diesel in Petrol symptoms, and in the event that you recognise any of them stop 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.
