Mercedes Fuel Drain


Putting Petrol in a Diesel Mercedes is a common problem. And its remedy depends upon several things. Assuming you would like to know what it is advisable to do to sort it out then keep reading.
Listed below are the most crucial factors to be aware of whenever determining whether or not to have a fuel drain:

  1. Exactly how much Petrol did you put into the Mercedes, taking into consideration that the fuel capacity of the Mercedes CLC 220 CDI is normally about 62 litres?
    1. A modest quantity of Petrol, less than 3.1 litres of Petrol in a Diesel CLC 220 CDI will normally not be a big problem. Experience has proven to us that an amount less than 3.1 litres (which is almost 5% of the total fuel tank) is quite often capable of being adequately diluted through wholly filling the tank with Diesel.
      It is rather uncommon to find a car having issues with less than 5% incorrect fuel contamination. Remember that it is infrequently found - not impossible to find. There are actually certain automobiles that don't endure any quantity of fuel contamination whatsoever.
    2. Somewhere between 3.1 and 6.2 litres of Petrol in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our working experience has confirmed that as many motorists get away with this as those people who don't. Whenever you are deciding whether to chance it and just top it up consider that it is the same as betting everything on black - you have a 50/50 chance of it working out.
    3. Anything above 6.2 litres of Petrol in your Diesel CLC 220 CDI really should straightaway be drained because your likelihood of driving with that quantity of contamination is undoubtedly below one in 50 - extremely huge odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you spotted any performance issues since putting the wrong fuel in your CLC 220 CDI? If that's the case, have it drained regardless of the quantity of Petrol or the contamination percentage. Continually running a car that is now beginning to suffer the effect of fuel contamination can just result in increasing amounts of damage being caused to the fuel system components.
  3. Are you interested in security?
    Simply get it drained. No matter the contamination percentage, there is inevitably some amount of risk resulting from operating a Diesel engine on fuel contaminated with Petrol. Possible final outcomes of driving a car on the wrong fuel normally include the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the commonest Petrol in Diesel symptoms, and should you detect any of them stop and have 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?


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.
