Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a fairly typical error. And its remedy depends upon a few things. If you want to know what it is advisable to do about it then keep reading.
These are the most important variables to be aware of when choosing whether or not to have your car drained:

  1. What amount of Diesel did you put in the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes C280 is in most cases approximately 62 litres?
    1. A modest amount of Diesel, something like 3.1 litres of Diesel in a Petrol C280 will more often than not not really be a significant problem. Experience has shown us that anything less than 3.1 litres (which is almost 5% of the entire fuel tank) is frequently capable of being completely diluted by means of completely topping the tank with the right fuel.
      It's very unusual to encounter a car going through difficulties due to less than 5% wrong fuel contamination. Be aware that it's rare - definitely not impossible to encounter. There are certain vehicles that don't endure any amount of fuel contamination in the slightest.
    2. Between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 situation. Our working experience has demonstrated that as many drivers get away with it as those people who don't. When you are deciding whether to chance it and just simply fill it up recognise that it is exactly like betting all of it on black - you've got a 50/50 possibility of it being ok.
    3. Anything over 6.2 litres of Diesel in a Petrol C280 should really immediately be drained out seeing that your likelihood of getting away with this level of contamination is very likely below one in 50 - seriously long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance troubles since putting the wrong fuel in the C280? If you have, get it drained no matter the volume of Diesel or even the contamination ratio. Continually driving a vehicle that is currently beginning to suffer the consequences of fuel contamination will probably definitely lead to more and more damage affecting your fuel system.
  3. Are you interested in peace of mind?
    Simply get it emptied. Regardless of the contamination ratio, there is invariably a certain level of danger linked with driving a Petrol vehicle on Petrol contaminated with the wrong fuel. Possible results of driving on the wrong fuel include the engine refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are some of the commonest Diesel in Petrol signs and symptoms, and in the event that you observe any of them stop and get it drained right away.

Diesel in Petrol Questions

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.
