Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a usual mistake to make. And its remedy depends upon a variety of things. In the event that you would like to know what to do to fix it then please read on.
Listed here the most crucial factors to take into consideration whenever choosing whether to have a fuel drain:

  1. Exactly how much Petrol have you put in to the Mercedes, keeping in mind that the fuel tank capacity of the Mercedes C270 CDI is probably approximately 62 litres?
    1. A tiny quantity of Petrol, as little as 3.1 litres of Petrol in a Diesel C270 CDI will most of the time not be a massive problem. Experience has taught us that quantities under 3.1 litres (almost 5% of the entire fuel tank volume) is usually able to be completely diluted by completely topping up the remainder of the tank with Diesel.
      It's relatively uncommon to find an automobile experiencing problems because of under 5% wrong fuel contamination. Keep in mind it's infrequent - certainly not impossible to find. You will discover certain cars that will not stand any amount of fuel contamination whatsoever.
    2. Anywhere 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 shown us that as many people get away with this as those people who don't. When figuring out whether or not to chance it and basically fill it up remember that it is exactly like gambling everything on black - you have a 50/50 chance of it being ok.
    3. Anything more than 6.2 litres of Petrol in a Diesel C270 CDI really should immediately be drained because your probability of driving with this level of contamination is more than likely less than one in fifty - really big odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you detected any kind of performance issues as a result of putting the bad fuel in your C270 CDI? In that case, have it removed no matter the quantity of Petrol or the contamination ratio. Proceeding to run driving an automobile that is now beginning to suffer the consequences of fuel contamination will just end up in progressively more harm being done to the fuel system.
  3. Are you looking for security?
    Then get it removed. Regardless of the contamination percentage, there is always a certain level of threat resulting from operating a Diesel engine on fuel contaminated with Petrol. Probable consequences of driving a vehicle on the wrong fuel normally include the engine refusing to start, running lumpy, lack of power, wearing of the high-pressure pump, worn out or blocked injectors, and so on. These are several of the commonest Petrol in Diesel symptoms, and if you notice any of them then cease driving and have it removed 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.
