Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a usual error. And exactly what you have to do about it is determined by a number of things. If perhaps you would like to find out what you ought to do to sort it out then stay with me.
Listed below are the most crucial factors to be aware of when making a decision whether to get it drained:

  1. What level of Diesel did you put in the Mercedes, taking into account that the fuel capacity of your Mercedes C300 is in most cases approximately 66 litres?
    1. Hardly any Diesel, less than 3.3 litres of Diesel in a Petrol C300 will generally not be a major problem. Experience has proven to us that anything less than 3.3 litres (5% of the entire fuel tank volume) is very often capable of being adequately diluted through completely filling up the rest of the tank with the correct fuel.
      It is extremely rare to come across a car or truck going through problems because of below 5% incorrect fuel contamination. Be aware that it's unusual - definitely not impossible to find. You will discover a few cars that will not stand any level of contamination at all.
    2. Somewhere between 3.3 and 6.6 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 scenario. Our working experience has demonstrated that as many people get away with it as all those who don't. Whenever you are figuring out whether to chance it and simply top it up recognise that it is much like gambling your car on black - you have got a 50/50 possibility of it working out.
    3. Anything over 6.6 litres of Diesel in your Petrol C300 must right away be drained seeing that your likelihood of driving with this quantity of contamination is more than likely less than one in 50 - definitely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you observed any performance concerns after putting the incorrect fuel in your C300? If so, have it drained no matter the amount of Diesel or the contamination percentage. Proceeding to run running a vehicle that is now beginning to suffer from the effects of fuel contamination can definitely result in progressively more damage being done to the fuel system components.
  3. Are you interested in peace of mind?
    You should get it emptied. Regardless of contamination percentage, there is invariably a certain level of danger affiliated with driving a Petrol vehicle on Petrol contaminated with Diesel. Likely outcomes of driving on the wrong fuel include things like the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are some of the commonest Diesel in Petrol signs or symptoms, and in the event that you detect any of them then stop and get it drained right now.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
