BMW Fuel Drain

ABOUT

Filling Petrol in a Diesel BMW is a common mistake to make. And its remedy varies according to a variety of things. If perhaps you would like to know what you have to do to fix it then keep reading.
Listed below are the main variables to be aware of whenever determining whether or not to have your car drained:

  1. Exactly how much Petrol have you put into the BMW, considering that the fuel tank capacity of the BMW 430d is normally about 60 litres?
    1. Hardly any Petrol, as little as 3 litres of Petrol in a Diesel 430d will generally not be a massive problem. Experience has proven to us that quantities less than 3 litres (which is about 5% of the entire fuel tank capacity) is quite often capable of being adequately diluted through totally topping the rest of the tank with Diesel.
      It is highly uncommon to come across a vehicle having problems due to lower than 5% incorrect fuel contamination. Bear in mind that it is very uncommon - definitely not impossible to encounter. You will discover certain vehicles that will not endure any level of contamination whatsoever.
    2. Somewhere between 3 and 6 litres of Petrol in the BMW (from 5 to 10%) is a 50/50 scenario. Our working experience has shown that as many drivers get away with it as all those who don't. Whenever you are figuring out whether to risk it and simply fill it up recognise that it is much like betting your car on black - you have a 50/50 chance of it working.
    3. Anything in excess of 6 litres of Petrol in your Diesel 430d really should right away be removed because your probability of getting away with that amount of contamination is probably below one in fifty - really long odds.
  2. Put some Petrol in a Diesel BMW and drove it: Have you seen any performance difficulties as a result of putting the wrong fuel in the 430d? If so, get it emptied regardless of the quantity of Petrol or the contamination percentage. Proceeding to drive driving a car that is already starting to suffer from the consequences of fuel contamination can typically result in more and more harm affecting your fuel system.
  3. Do you want security?
    Then simply just get it removed. Regardless of contamination ratio, there is invariably some degree of risk connected to driving a Diesel engine on Diesel contaminated with Petrol. Likely implications of driving a car on the incorrect fuel normally include the engine refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, and the like. These are some of the commonest Petrol in Diesel symptoms, and in the event that you recognise any of them stop and have it removed right away.

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.
