Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a fairly typical mistake. And exactly what you have to do about it is based on several different things. If you want to know what you should do about it then keep reading.
Listed here are the main factors to consider whenever figuring out whether or not to get a fuel drain:

  1. What amount of Diesel have you put in the Mercedes, keeping in mind that the fuel capacity of the Mercedes S320 is normally approximately 100 litres?
    1. A small amount of Diesel, as little as 5 litres of Diesel in a Petrol S320 will in most cases not necessarily be a big problem. Experience has shown us that an amount less than 5 litres (close to 5% of the whole fuel tank volume) is generally capable of being completely diluted by means of totally filling up the rest of the tank with the right fuel.
      It's highly uncommon to encounter a motor vehicle having difficulties with below 5% incorrect fuel contamination. Do not forget that it's unusual - definitely not impossible to find. There are a number of motor vehicles that will not endure any amount of contamination whatsoever.
    2. Somewhere between 5 and 10 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 scenario. Our experience demonstrates that as many drivers get away with this as those people who don't. Whenever deciding upon whether or not to chance it and just simply fill it up recognise that it is exactly like wagering all of it on black - you will have a 50/50 chance of it working out.
    3. Anything over 10 litres of Diesel in a Petrol S320 should as soon as possible be drained out seeing as your likelihood of getting away with that quantity of contamination is more than likely less than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you seen any kind of performance troubles since putting the incorrect fuel in your S320? If you have, have it drained irrespective of the quantity of Diesel or even the contamination ratio. Continuing to drive running an automobile that is already beginning to suffer from the effect of fuel contamination can typically bring about even more damage affecting your fuel system components.
  3. Are you looking for security?
    You should get it drained. Regardless of contamination percentage, there is invariably a certain level of danger connected to operating a Petrol motor on Petrol contaminated with the incorrect fuel. Possible final outcomes of driving a car on the wrong fuel include the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn or blocked injectors, etc. These are several of the most common Diesel in Petrol symptoms, and if you detect any of them then stop driving and have it removed as soon as possible.

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.
