BMW Fuel Drain

ABOUT

Filling up with Diesel in a Petrol BMW is a common mistake. And what you should do about it varies according to several factors. Assuming you would like to find out what it is advisable to do to sort it out then stay with me.
Listed here the main variables to to consider when deciding on whether or not to have a fuel drain:

  1. How much Diesel have you put in to the BMW, taking into consideration that the fuel tank capacity of your BMW 523i Touring is probably roughly 70 litres?
    1. A small quantity of Diesel, less than 3.5 litres of Diesel in a Petrol 523i Touring will usually not really be a huge problem. Experience has shown us that anything under 3.5 litres (which is 5% of the total fuel tank capacity) is often able to be completely diluted by means of entirely topping the rest of the tank with the correct fuel.
      It is highly uncommon to find a car having difficulties with below 5% wrong fuel contamination. Do not forget that it is infrequent - definitely not impossible to encounter. There are some motor vehicles that don't stand any amount of fuel contamination in the slightest.
    2. Between 3.5 and 7 litres of Diesel in the BMW (5 to 10%) is really a 50/50 condition. Our expertise has shown us that as many drivers get away with it as those who break down. When you are figuring out whether or not to risk it and just fill it up remember that it is the same as gambling your car on black - you have a 50/50 possibility of it working.
    3. Anything over 7 litres of Diesel in your Petrol 523i Touring ought to immediately be drained out since your likelihood of getting away with that amount of contamination is probably less than one in 50 - definitely big odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you spotted any performance problems ever since putting the wrong fuel in the 523i Touring? In that case, have it drained irrespective of the amount of Diesel or even the contamination ratio. Continually running a car that is beginning to suffer from the effect of fuel contamination can only end up in more harm affecting your fuel system components.
  3. Do you need peace of mind?
    In that case get it removed. Regardless of contamination percentage, there is inevitably some extent of risk connected to driving a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely outcomes of driving a car on the wrong fuel normally include the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most common Diesel in Petrol symptoms, and if you observe any of them then stop and have it removed right now.

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.
