Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a regular problem. And exactly what you want to do about it is based on various things. In case you want to find out what you ought to do to sort it out then read on.
Let us discuss the most crucial variables to think about when deciding on whether or not to get a fuel drain:

  1. What amount of Diesel have you put in to the Mercedes, considering that the fuel capacity of your Mercedes B200 is normally approximately 54 litres?
    1. A modest amount of Diesel, less than 2.7 litres of Diesel in a Petrol B200 will generally not be a significant problem. Experience has shown us that an amount under 2.7 litres (which is 5% of the overall fuel tank) is quite often capable of being completely diluted simply by totally topping the rest of the tank with the correct fuel.
      It's very uncommon to come across a vehicle suffering from problems because of less than 5% wrong fuel contamination. Remember that it is very unusual - certainly not impossible to find. You can get a number of vehicles that will not endure any quantity of fuel contamination whatsoever.
    2. Somewhere between 2.7 and 5.4 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our experience has shown us that as many people get away with it as all those who break down. Whenever you are figuring out whether to chance it and simply top it up remember that it is just like gambling all of it on black - you have a 50/50 chance of it being ok.
    3. Anything above 5.4 litres of Diesel in a Petrol B200 really should straight away be drained seeing that your probability of driving with this amount of contamination is certainly less than one in 50 - truly huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance difficulties since putting the incorrect fuel in your B200? If that's the case, get it drained no matter the volume of Diesel or even the contamination percentage. Continually driving a vehicle that is already starting to suffer from the effects of fuel contamination will likely result in more harm being done to the fuel system.
  3. Do you need reassurance?
    You should get it removed. Regardless of contamination percentage, there is inevitably some degree of risk connected to operating a Petrol motor on Petrol contaminated with Diesel. Likely final outcomes of driving on the wrong fuel normally include the motor not starting, running unevenly, losing power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are some of the most typical Diesel in Petrol warning signs, and if you notice any of them stop and get it drained right now.

Diesel in Petrol FAQs

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?


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?


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?


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 Petrol 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.
