Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a usual mistake. And exactly what you need to do about it hinges on several things. If you would like to know what you need to do to fix it then please read on.
Listed here are the main factors to take into consideration when deciding on whether to have a fuel drain:

  1. What amount of Diesel have you put in the Mercedes, bearing in mind that the fuel capacity of the Mercedes C43 AMG is usually approximately 62 litres?
    1. A small quantity of Diesel, something like 3.1 litres of Diesel in a Petrol C43 AMG will in most cases not be a huge problem. Experience has shown us that anything under 3.1 litres (approximately 5% of the entire fuel tank volume) is often capable of being sufficiently diluted simply by wholly filling the rest of the tank with the right fuel.
      It's rather rare to encounter a vehicle suffering from difficulties with under 5% incorrect fuel contamination. Keep in mind it's uncommon - in no way impossible to encounter. You can get some motor vehicles that don't endure any degree of fuel contamination whatsoever.
    2. In between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our practical experience has shown that as many people get away with it as those people who break down. When figuring out whether or not to chance it and basically top it up remember that it is much like betting all of it on black - you have a 50/50 possibility of it working out.
    3. Anything over 6.2 litres of Diesel in your Petrol C43 AMG should promptly be removed as your likelihood of getting away with this quantity of contamination is more than likely less than one in fifty - truly long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance concerns as a result of putting the wrong fuel in your C43 AMG? If that's the case, get it drained regardless of the quantity of Diesel or even the contamination percentage. Continuing to drive driving a motor vehicle that is starting to suffer the consequences of fuel contamination will probably likely bring about even more harm being done to the fuel system.
  3. Are you looking for assurance?
    Simply get it emptied. Regardless of contamination ratio, there is always a certain level of threat connected to operating a Petrol motor on fuel contaminated with the wrong fuel. Likely results of driving a car on the incorrect fuel can include the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, damaged or clogged injectors, and the like. These are several of the most common Diesel in Petrol symptoms, and if you recognise any of them stop and get it removed right now.

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.
