Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a common error. And its remedy depends on a few factors. Assuming you would like to find out what you must do about it then read on.
Listed below are the key variables to to consider whenever making a decision whether or not to get a fuel drain:

  1. What amount of Petrol did you put into the Mercedes, taking into account that the fuel tank capacity of your Mercedes GLK 320 CDI is in most cases approximately 66 litres?
    1. Hardly any Petrol, something like 3.3 litres of Petrol in a Diesel GLK 320 CDI will normally not really be a massive problem. Experience has demonstrated to us that anything under 3.3 litres (which is about 5% of the overall fuel tank volume) is quite often capable of being adequately diluted simply by totally filling up the remainder of the tank with the correct fuel.
      It's quite rare to come across a car or truck going through issues with less than 5% incorrect fuel contamination. Do not forget that it's uncommon - in no way impossible to encounter. You will discover certain vehicles that don't endure any amount of contamination whatsoever.
    2. Anywhere between 3.3 and 6.6 litres of Petrol in the Mercedes (5 to 10%) is a 50/50 situation. Our experience has proven that as many people get away with this as those who don't. When deciding whether to chance it and basically top it up recognise that it is very much like gambling it all on black - you've got a 50/50 possibility of it working out.
    3. Anything above 6.6 litres of Petrol in a Diesel GLK 320 CDI really should promptly be drained out seeing as your probability of getting away with that amount of contamination is undoubtedly below one in 50 - definitely long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you noted any kind of performance troubles as a result of putting the bad fuel in your GLK 320 CDI? If so, get it emptied regardless of the amount of Petrol or the contamination percentage. Still driving a vehicle that is currently starting to suffer the effects of wrong fuel contamination will typically lead to more damage affecting your fuel system components.
  3. Do you want reassurance?
    Simply get it removed. No matter the contamination percentage, there is invariably some extent of threat connected to running a Diesel engine on fuel contaminated with Petrol. Probable outcomes of driving on the wrong fuel can include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or blocked injectors, etc. These are a few of the most typical Petrol in Diesel warning signs, and if you observe any of them then stop driving and get it drained asap.

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.
