Mercedes Fuel Drain

ABOUT

Filling Petrol in a Diesel Mercedes is a common error. And its remedy is dependent upon several different things. If perhaps you want to find out what you must do about this then stay with me.
Right here are the main factors to take into account whenever figuring out whether to get the car drained:

  1. How much Petrol have you put in to the Mercedes, considering that the fuel capacity of your Mercedes GL 320 CDI is probably roughly 100 litres?
    1. A small amount of Petrol, as little as 5 litres of Petrol in a Diesel GL 320 CDI will usually not necessarily be a significant problem. Experience has taught us that quantities less than 5 litres (close to 5% of the entire fuel tank volume) is quite often able to be completely diluted by means of totally filling up the tank with Diesel.
      It is pretty rare to encounter a car or truck experiencing difficulties because of less than 5% wrong fuel contamination. Please remember it is uncommon - in no way impossible to find. There are a number of vehicles that don't stand any amount of fuel contamination whatsoever.
    2. Anywhere between 5 and 10 litres of Petrol in the Mercedes (from 5 to 10%) is a 50/50 situation. Our experience demonstrates that as many people get away with it as all those who break down. Whenever deciding upon whether to chance it and just simply fill it up bear in mind that it is very much like gambling your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything over 10 litres of Petrol in your Diesel GL 320 CDI ought to immediately be drained seeing as your likelihood of driving with this amount of contamination is in all likelihood lower than one in 50 - truly long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you detected any kind of performance problems since putting the bad fuel in your GL 320 CDI? If that's the case, get it emptied no matter the amount of Petrol or even the contamination ratio. Continuing to drive driving a vehicle that is already beginning to suffer from the effect of wrong fuel contamination can definitely result in more damage being caused to your fuel system parts.
  3. Do you need reassurance?
    You should get it removed. Regardless of contamination percentage, there is always some amount of danger connected to operating a Diesel motor on Diesel contaminated with Petrol. Likely consequences of driving a vehicle on the wrong fuel include the engine not starting, running unevenly, reduced power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are a few of the most typical Petrol in Diesel signs or symptoms, and if you notice any of them then stop and have it removed asap.

Petrol in Diesel Questions

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?

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