Mercedes Fuel Drain


Filling up with Petrol in a Diesel Mercedes is a usual error. And its remedy is based on a few factors. In the event that you would like to know what you ought to do to fix it then keep reading.
Listed here are the most important variables to to consider when figuring out whether or not to get the car drained:

  1. How much Petrol have you put in the Mercedes, taking into account that the fuel capacity of your Mercedes GL 350 CDI is normally about 100 litres?
    1. A modest amount of Petrol, less than 5 litres of Petrol in a Diesel GL 350 CDI will typically not be a huge problem. Experience has proven to us that an amount less than 5 litres (roughly 5% of the total fuel tank) is very often able to be sufficiently diluted by thoroughly topping the rest of the tank with the appropriate fuel.
      It is quite rare to find a motor vehicle having problems because of below 5% wrong fuel contamination. Do not forget that it is very unusual - definitely not impossible to find. There are actually certain vehicles that won't endure any amount of fuel contamination at all.
    2. Anywhere between 5 and 10 litres of Petrol in the Mercedes (from 5 to 10%) is more of a 50/50 situation. Our practical experience has proven that as many motorists get away with it as those people who don't. When you are figuring out whether or not to chance it and simply fill it up consider that it is very much like gambling all of it on black - you've got a 50/50 chance of it working out.
    3. Anything over 10 litres of Petrol in a Diesel GL 350 CDI should right away be drained seeing that your probability of getting away with this amount of contamination is in all likelihood lower than one in fifty - seriously long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you noticed any performance troubles since putting the bad fuel in your GL 350 CDI? If so, get it drained irrespective of the amount of Petrol or even the contamination percentage. Proceeding to run running an automobile that is already beginning to suffer from the effect of wrong fuel contamination will likely cause increasing amounts of damage affecting your fuel system.
  3. Do you need assurance?
    Then simply just get it emptied. Regardless of contamination ratio, there is inevitably some degree of risk caused by operating a Diesel motor on fuel contaminated with the incorrect fuel. Probable implications of driving a vehicle on the incorrect fuel include the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, damaged or blocked injectors, and the like. These are a few of the commonest Petrol in Diesel warning signs, and in the event that you observe any of them stop driving and have it drained right away.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
