Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a regular error. And what you need to do about it hinges on various things. In the event that you would like to know what it is best to do about it then continue reading.
Here are the most crucial factors to take into account whenever choosing whether to have the car drained:

  1. How much Diesel did you put into the Mercedes, taking into consideration that the fuel tank capacity of your Mercedes SL 500 is usually about 80 litres?
    1. A tiny amount of Diesel, less than 4 litres of Diesel in a Petrol SL 500 will more often than not not really be a big problem. Experience has proven to us that anything under 4 litres (almost 5% of the entire fuel tank) is generally capable of being completely diluted through entirely filling the rest of the tank with Petrol.
      It's very rare to find a car experiencing difficulties because of under 5% wrong fuel contamination. Please remember it is very unusual - in no way impossible to encounter. You will discover a number of motor vehicles that will not endure any degree of fuel contamination in the slightest.
    2. Somewhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 scenario. Our practical experience demonstrates that as many motorists get away with it as those people who don't. When trying to decide whether or not to risk it and basically top it up consider that it is very much like gambling it all on black - you have a 50/50 possibility of it being ok.
    3. Anything over 8 litres of Diesel in your Petrol SL 500 should really right away be drained out because your probability of succeeding with that amount of contamination is probably less than one in fifty - truly huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you spotted any performance difficulties since putting the incorrect fuel in your SL 500? If you have, get it removed regardless of the quantity of Diesel or even the contamination ratio. Still running a vehicle that is now starting to suffer the consequences of fuel contamination will probably just be responsible for progressively more harm being caused to your fuel system.
  3. Are you interested in assurance?
    Then simply just get it emptied. No matter the contamination percentage, there is invariably some degree of danger connected to running a Petrol motor on Petrol contaminated with Diesel. Possible outcomes of driving a car on the incorrect fuel include things like the motor refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, damaged or blocked injectors, etc. These are a few of the commonest Diesel in Petrol warning signs, and if you recognise any of them stop driving and get it drained asap.

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

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.
