Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a fairly typical mistake. And its solution is determined by a number of things. If you would like to know what it is advisable to do to sort it out then stay with me.
These are the most important factors to to consider when deciding on whether to get it drained:

  1. What level of Diesel did you put into the Mercedes, considering that the fuel capacity of the Mercedes S600 L is most likely around 100 litres?
    1. A small quantity of Diesel, less than 5 litres of Diesel in a Petrol S600 L will typically not really be a major problem. Experience has shown us that quantities under 5 litres (which is almost 5% of the overall fuel tank) is frequently able to be sufficiently diluted by means of completely topping up the rest of the tank with the correct fuel.
      It's extremely unusual to find a motor vehicle suffering from issues with below 5% incorrect fuel contamination. Be aware that it's unusual - not impossible to encounter. You can get some automobiles that don't endure any level of contamination at all.
    2. Anywhere between 5 and 10 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 scenario. Our working experience has revealed that as many motorists get away with it as those who break down. Whenever you are deciding whether to risk it and simply top it up remember that it is the same thing as betting all of it on black - you have a 50/50 possibility of it being ok.
    3. Anything over 10 litres of Diesel in your Petrol S600 L must promptly be drained out seeing that your probability of driving with that level of contamination is very likely lower than one in 50 - definitely big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you seen any performance difficulties since putting the bad fuel in your S600 L? If you have, have it drained no matter the volume of Diesel or the contamination ratio. Continually driving an automobile that is now beginning to suffer the effects of wrong fuel contamination will probably definitely lead to increasing amounts of damage being done to your fuel system components.
  3. Would you like peace of mind?
    In that case get it removed. Regardless of contamination ratio, there is always a certain level of risk resulting from operating a Petrol vehicle on fuel contaminated with Diesel. Likely results of driving a car on the incorrect fuel include things like the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, damaged or bunged injectors, etc. These are some of the most common Diesel in Petrol symptoms, and should you notice any of them stop and get it removed asap.

Refrain from getting any jack-of-all-trades to try to drain your automobile. We are Mercedes experts and possess the skills and working experience needed to ensure you are back on the road with minimal hassle or trouble.

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.
