Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regularly occurring mistake. And what you want to do about it varies according to several different things. Assuming you want to know what to do to fix it then keep reading.
Right here are the main factors to think about whenever determining whether to have a fuel drain:

  1. What amount of Diesel did you put in to the Mercedes, taking into account that the fuel capacity of the Mercedes CLK 55 AMG is normally around 62 litres?
    1. A modest quantity of Diesel, less than 3.1 litres of Diesel in a Petrol CLK 55 AMG will more often than not not be a significant problem. Experience has proven to us that quantities under 3.1 litres (which is roughly 5% of the entire fuel tank capacity) is sometimes able to be completely diluted by means of entirely topping up the rest of the tank with the appropriate fuel.
      It's extremely unusual to come across a vehicle having difficulties due to below 5% incorrect fuel contamination. Bear in mind that it is uncommon - definitely not impossible to find. There are a number of automobiles that will not stand any quantity of fuel contamination in the slightest.
    2. Somewhere between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 situation. Our working experience has demonstrated that as many people get away with this as all those who break down. When deciding upon whether to risk it and basically fill it up remember that it is just like betting all of it on black - you've got a 50/50 possibility of it working.
    3. Anything above 6.2 litres of Diesel in your Petrol CLK 55 AMG really should promptly be drained out seeing as your probability of driving with this level of contamination is in all likelihood below one in 50 - seriously big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance difficulties after putting the incorrect fuel in your CLK 55 AMG? If you have, have it removed no matter the quantity of Diesel or even the contamination ratio. Still driving an automobile that is starting to suffer from the effects of fuel contamination will only end up in even more damage affecting your fuel system components.
  3. Would you like reassurance?
    Then simply just get it emptied. Regardless of the contamination ratio, there is inevitably some degree of threat in connection with driving a Petrol engine on Petrol contaminated with Diesel. Likely results of driving on the wrong fuel include the motor not starting, running unevenly, loss in power, wearing of the high-pressure pump, worn out or bunged injectors, and the like. These are some of the most common Diesel in Petrol signs and symptoms, and should you observe any of them then stop driving and have it drained immediately.

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.
