Mercedes Fuel Drain


Putting Petrol in a Diesel Mercedes is a usual error. And its solution varies according to a few factors. In case you want to find out what you should do about this then keep on reading.
Listed here are the main variables to keep in mind whenever figuring out whether to have a fuel drain:

  1. How much Petrol have you put in to the Mercedes, bearing in mind that the fuel capacity of your Mercedes ML 320 CDI is in most cases about 95 litres?
    1. Hardly any Petrol, less than 4.75 litres of Petrol in a Diesel ML 320 CDI will normally not be a big problem. Experience has shown us that quantities less than 4.75 litres (5% of the entire fuel tank capacity) is quite often able to be adequately diluted simply by entirely filling up the tank with Diesel.
      It is rather rare to encounter a car having problems due to under 5% incorrect fuel contamination. Be aware that it's unusual - definitely not impossible to find. There are a number of automobiles that will not stand any amount of contamination at all.
    2. Between 4.75 and 9.5 litres of Petrol in the Mercedes (5 to 10%) is a 50/50 situation. Our experience has proven that as many motorists get away with this as all those who don't. Whenever you are figuring out whether to chance it and just simply fill it up bear in mind that it is the same as gambling all of it on black - you've got a 50/50 possibility of it working.
    3. Anything in excess of 9.5 litres of Petrol in your Diesel ML 320 CDI should really immediately be drained out as your likelihood of getting away with this quantity of contamination is in all likelihood below one in fifty - seriously big odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you seen any kind of performance troubles ever since putting the bad fuel in your ML 320 CDI? If you have, have it removed no matter the quantity of Petrol or the contamination percentage. Continuing to drive driving a car that is currently starting to suffer from the consequences of fuel contamination will just be responsible for progressively more harm affecting the fuel system parts.
  3. Are you looking for peace of mind?
    Then simply just get it removed. Regardless of the contamination percentage, there is inevitably some degree of threat connected with driving a Diesel motor on Diesel contaminated with Petrol. Likely outcomes of driving on the wrong fuel include things like the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn or blocked injectors, and so on. These are a few of the commonest Petrol in Diesel warning signs, and in the event that you observe any of them then stop driving and get it drained right away.

Petrol in Diesel FAQs

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?


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?


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?


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?


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?


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?


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.
