Mercedes Fuel Drain


Putting Petrol in a Diesel Mercedes is a very common mistake to make. And its remedy is dependent upon several different things. In case you would like to find out what you ought to do about it then keep on reading.
Here are the most important factors to keep in mind when making a decision whether to have a fuel drain:

  1. What amount of Petrol have you put in the Mercedes, considering that the fuel tank capacity of your Mercedes C200 CDI is most likely about 62 litres?
    1. Hardly any Petrol, less than 3.1 litres of Petrol in a Diesel C200 CDI will typically not necessarily be a significant problem. Experience has taught us that anything under 3.1 litres (approximately 5% of the total fuel tank) is quite often able to be sufficiently diluted by entirely filling the tank with Diesel.
      It's pretty rare to encounter an automobile experiencing issues with lower than 5% wrong fuel contamination. Remember that it is very unusual - certainly not impossible to find. You will discover some motor vehicles that will not endure any amount of contamination whatsoever.
    2. Somewhere between 3.1 and 6.2 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 scenario. Our working experience has proven that as many people get away with it as all those who don't. When deciding whether to risk it and simply top it up consider that it is exactly like betting your car on black - you've got a 50/50 possibility of it working.
    3. Anything in excess of 6.2 litres of Petrol in your Diesel C200 CDI should straight away be drained seeing that your probability of driving with that amount of contamination is almost certainly less than one in 50 - extremely huge odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you detected any kind of performance troubles as a result of putting the bad fuel in your C200 CDI? If you have, have it emptied no matter the volume of Petrol or even the contamination ratio. Continuing to drive running an automobile that is beginning to suffer the effects of wrong fuel contamination will probably only result in even more harm affecting the fuel system parts.
  3. Are you looking for peace of mind?
    Simply get it emptied. Whatever the contamination ratio, there is invariably some extent of threat in connection with running a Diesel vehicle on fuel contaminated with the wrong fuel. Possible outcomes of driving a vehicle on the wrong fuel include the motor refusing to start, running lumpy, lack of power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are several of the commonest Petrol in Diesel signs or symptoms, and if you notice any of them then cease driving and get it removed immediately.

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.
