Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a regular mistake to make. And what you need to do about it will depend on several things. If you would like to find out what you have to do to fix it then read on.
Listed here the key variables to consider whenever deciding on whether to get the car drained:

  1. What amount of Diesel have you put in to the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes SL 55 AMG is in most cases approximately 80 litres?
    1. A small amount of Diesel, something like 4 litres of Diesel in a Petrol SL 55 AMG will quite often not really be a huge problem. Experience has taught us that an amount under 4 litres (which is roughly 5% of the entire fuel tank volume) is in many instances capable of being sufficiently diluted simply by entirely topping the rest of the tank with Petrol.
      It's extremely unusual to find an automobile suffering from issues with less than 5% wrong fuel contamination. Please remember it is rare - certainly not impossible to find. There are some motor vehicles that will not endure any amount of fuel contamination at all.
    2. In between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 condition. Our practical experience has confirmed that as many motorists get away with this as those who don't. Whenever you are deciding whether or not to risk it and simply top it up remember that it is very much like wagering everything on black - you have a 50/50 chance of it being ok.
    3. Anything more than 8 litres of Diesel in a Petrol SL 55 AMG ought to immediately be drained out because your likelihood of succeeding with this level of contamination is more than likely lower than one in fifty - really long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any performance issues ever since putting the bad fuel in the SL 55 AMG? In that case, get it removed regardless of the quantity of Diesel or even the contamination percentage. Continuing to drive running a car that is beginning to suffer from the consequences of fuel contamination will probably likely end up in even more harm affecting the fuel system.
  3. Are you looking for reassurance?
    Then get it emptied. Regardless of the contamination ratio, there is invariably some extent of danger connected to running a Petrol vehicle on Petrol contaminated with Diesel. Possible final outcomes of driving on the wrong fuel include things like the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and should you recognise any of them then stop and have it removed immediately.

Diesel in Petrol FAQs

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.
