Mercedes Fuel Drain


Filling up with Petrol in a Diesel Mercedes is a regularly occurring mistake to make. And exactly what you want to do about it is based on a number of things. In case you would like to know what you must do about it then continue reading.
These are the key factors to take into consideration whenever choosing whether or not to have the car drained:

  1. How much Petrol did you put in the Mercedes, considering that the fuel capacity of your Mercedes E200 CDI is most likely around 70 litres?
    1. Hardly any Petrol, less than 3.5 litres of Petrol in a Diesel E200 CDI will usually not be a major problem. Experience has shown us that an amount less than 3.5 litres (5% of the total fuel tank capacity) is generally capable of being adequately diluted through completely topping the remainder of the tank with Diesel.
      It is extremely unusual to come across an automobile suffering from difficulties with lower than 5% wrong fuel contamination. Do not forget that it is very unusual - certainly not impossible to encounter. There are a few cars that don't endure any amount of contamination whatsoever.
    2. Between 3.5 and 7 litres of Petrol in the Mercedes (from 5 to 10%) is really a 50/50 scenario. Our practical experience demonstrates that as many people get away with this as those people who don't. Whenever deciding whether to chance it and simply top it up bear in mind that it is the same thing as betting it all on black - you have got a 50/50 possibility of it working.
    3. Anything more than 7 litres of Petrol in a Diesel E200 CDI should really immediately be drained because your probability of driving with this amount of contamination is undoubtedly lower than one in 50 - genuinely long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you seen any kind of performance issues after putting the incorrect fuel in the E200 CDI? If that's the case, get it removed regardless of the volume of Petrol or the contamination percentage. Proceeding to drive running a vehicle that is now beginning to suffer from the consequences of wrong fuel contamination will probably just be responsible for increasing amounts of damage affecting the fuel system components.
  3. Do you need security?
    Simply get it drained. Regardless of contamination percentage, there is invariably a certain level of danger affiliated with driving a Diesel vehicle on Diesel contaminated with Petrol. Likely final outcomes of driving on the wrong fuel can include the engine not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are some of the most typical Petrol in Diesel signs and symptoms, and should you recognise any of them then stop driving and have it drained right now.

Do not simply get any general so-and-so to try to repair your vehicle. We are Mercedes experts and have got the certification and practical experience required to make certain that you are back on the road with little hassle or trouble.

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.
