Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a regular problem. And exactly what you need to do about it depends upon a number of things. In the event that you would like to find out what you must do to fix it then read on.
Listed below are the most important variables to consider whenever determining whether to get a fuel drain:

  1. Exactly how much Diesel did you put into the Mercedes, taking into account that the fuel capacity of the Mercedes SL 300 is usually approximately 80 litres?
    1. A small amount of Diesel, as little as 4 litres of Diesel in a Petrol SL 300 will in most cases not be a big problem. Experience has demonstrated to us that an amount less than 4 litres (which is almost 5% of the fuel tank) is often capable of being sufficiently diluted simply by completely topping the tank with the appropriate fuel.
      It is extremely rare to find a car or truck experiencing problems due to less than 5% incorrect fuel contamination. Keep in mind it's rare - not impossible to find. You will discover certain cars that will not stand any degree of contamination in the slightest.
    2. Somewhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 condition. Our practical experience has confirmed that as many drivers get away with it as those people who don't. Any time you're deciding on whether or not to chance it and simply top it up consider that it is the same thing as gambling your car on black - you have a 50/50 possibility of it working.
    3. Anything above 8 litres of Diesel in your Petrol SL 300 must straight away be removed as your likelihood of succeeding with that quantity of contamination is very likely less than one in fifty - definitely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you observed any performance concerns since putting the incorrect fuel in the SL 300? If you have, get it drained regardless of the volume of Diesel or even the contamination percentage. Still running a car that is now starting to suffer the effect of wrong fuel contamination can likely cause more damage being caused to your fuel system.
  3. Do you want assurance?
    Then get it drained. Whatever the contamination ratio, there is always a certain level of danger connected with driving a Petrol vehicle on fuel contaminated with the wrong fuel. Probable outcomes of driving on the incorrect fuel can include the engine not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are several of the commonest Diesel in Petrol signs or symptoms, and should you recognise any of them then stop driving and get it removed asap.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
