BMW Fuel Drain

ABOUT

Filling Diesel in a Petrol BMW is a regular mistake to make. And its remedy is determined by various factors. In case you would like to find out what it is best to do about this then continue reading.
Here are the most crucial factors to be aware of when determining whether to have it drained:

  1. What level of Diesel did you put into the BMW, taking into account that the fuel capacity of the BMW 525xi is probably roughly 70 litres?
    1. A modest quantity of Diesel, something like 3.5 litres of Diesel in a Petrol 525xi will most of the time not necessarily be a huge problem. Experience has proven to us that quantities less than 3.5 litres (about 5% of the fuel tank volume) is in many instances able to be adequately diluted through totally topping up the remainder of the tank with the right fuel.
      It's very uncommon to come across a vehicle going through problems because of lower than 5% wrong fuel contamination. Remember that it's infrequently found - definitely not impossible to find. You will discover certain 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 (from 5 to 10%) is really a 50/50 scenario. Our practical experience demonstrates that as many motorists get away with this as all those who break down. When deciding upon whether or not to risk it and simply fill it up remember that it is the same thing as betting it all on black - you have got a 50/50 chance of it being ok.
    3. Anything more than 7 litres of Diesel in your Petrol 525xi should as soon as possible be drained because your probability of getting away with that quantity of contamination is more than likely lower than one in 50 - extremely huge odds.
  2. Put Diesel in a Petrol BMW and drove it: Have you seen any kind of performance concerns ever since putting the bad fuel in your 525xi? If that's the case, have it emptied regardless of the amount of Diesel or the contamination percentage. Continuing to run running a vehicle that is currently starting to suffer from the effects of fuel contamination will likely lead to more and more harm affecting the fuel system.
  3. Are you looking for reassurance?
    Then simply just get it drained. Regardless of the contamination ratio, there is invariably some amount of risk linked with operating a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely results of driving on the incorrect fuel normally include the engine not starting, running lumpy, loss of power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are several of the most typical Diesel in Petrol signs and symptoms, and should you observe any of them then stop driving and get it removed immediately.

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.
