Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a common mistake to make. And exactly what you want to do about it is determined by several different things. In the event that you would like to know what it is advisable to do about this then continue reading.
Right here are the key variables to to consider whenever deciding on whether to have a fuel drain:

  1. What level of Diesel did you put into the Mercedes, keeping in mind that the fuel tank capacity of your Mercedes C55 AMG is normally about 62 litres?
    1. Hardly any Diesel, as little as 3.1 litres of Diesel in a Petrol C55 AMG will in most situations not be a massive problem. Experience has shown us that quantities less than 3.1 litres (which is 5% of the whole fuel tank) is usually capable of being sufficiently diluted simply by entirely topping up the tank with Petrol.
      It is rather uncommon to encounter a car or truck having difficulties due to below 5% incorrect fuel contamination. Do not forget that it is infrequent - in no way impossible to find. There are actually a few automobiles that don't stand any amount of contamination at all.
    2. Between 3.1 and 6.2 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 condition. Our practical experience has shown that as many motorists get away with it as all those who break down. Any time you're figuring out whether to risk it and just simply fill it up bear in mind that it is much like gambling it all on black - you will have a 50/50 chance of it working out.
    3. Anything more than 6.2 litres of Diesel in a Petrol C55 AMG should right away be drained out seeing that your likelihood of getting away with this amount of contamination is more than likely below one in fifty - really huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance troubles as a result of putting the incorrect fuel in your C55 AMG? If so, get it emptied irrespective of the quantity of Diesel or even the contamination ratio. Proceeding to run running a motor vehicle that is starting to suffer the consequences of wrong fuel contamination will probably just end up in even more damage being caused to the fuel system components.
  3. Do you want assurance?
    Then simply just get it drained. Regardless of contamination ratio, there is always some degree of danger in connection with operating a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely outcomes of driving a car on the wrong fuel include the motor refusing to start, running unevenly, loss in power, wearing of the high-pressure pump, worn or bunged injectors, and so on. These are some of the commonest Diesel in Petrol symptoms, and should you recognise any of them then stop and get it drained asap.

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.
