Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a fairly typical error. And its solution is determined by a few factors. If you would like to know what you must do about this then read on.
Listed below are the most crucial variables to be aware of whenever determining whether or not to get it drained:

  1. What amount of Diesel did you put into the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes ML 55 AMG is most likely approximately 93 litres?
    1. A small quantity of Diesel, something like 4.65 litres of Diesel in a Petrol ML 55 AMG will in most cases not necessarily be a big problem. Experience has demonstrated to us that anything under 4.65 litres (which is about 5% of the overall fuel tank) is very often able to be adequately diluted through totally topping up the tank with the appropriate fuel.
      It's rather uncommon to find a motor vehicle having problems due to less than 5% incorrect fuel contamination. Keep in mind that it is rare - in no way impossible to find. You will discover a number of automobiles that don't stand any quantity of contamination at all.
    2. In between 4.65 and 9.3 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our practical experience has proven that as many people get away with it as those who don't. When you are trying to decide whether to chance it and just top it up consider that it is much like wagering it all on black - you have got a 50/50 possibility of it working.
    3. Anything over 9.3 litres of Diesel in a Petrol ML 55 AMG ought to immediately be drained seeing that your likelihood of getting away with this level of contamination is almost certainly lower than one in 50 - extremely huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you seen any kind of performance concerns after putting the incorrect fuel in the ML 55 AMG? If you have, get it drained no matter the amount of Diesel or even the contamination percentage. Proceeding to drive driving an automobile that is already starting to suffer the effects of fuel contamination will probably typically be responsible for even more damage being caused to the fuel system components.
  3. Do you need peace of mind?
    Then simply just get it drained. Regardless of the contamination percentage, there is invariably some extent of danger in connection with driving a Petrol engine on Petrol contaminated with Diesel. Probable consequences of driving on the wrong fuel include the motor not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are several of the most typical Diesel in Petrol signs and symptoms, and if you detect any of them then stop and get it drained right away.

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?


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.
