Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a very common mistake to make. And its solution depends on several different things. If perhaps you want to know what you ought to do to sort it out then please read on.
Right here are the most important factors to take into consideration whenever deciding on whether or not to have a fuel drain:

  1. What level of Petrol did you put in the Mercedes, taking into account that the fuel capacity of your Mercedes G350 kurz is in most cases about 96 litres?
    1. A modest amount of Petrol, something like 4.8 litres of Petrol in a Diesel G350 kurz will quite often not really be a big problem. Experience has demonstrated to us that an amount under 4.8 litres (almost 5% of the entire fuel tank volume) is usually capable of being adequately diluted by means of completely filling the tank with Diesel.
      It's rather uncommon to come across a car going through issues with under 5% incorrect fuel contamination. Bear in mind that it is very infrequent - not impossible to encounter. There are a few automobiles that won't stand any degree of contamination in the slightest.
    2. Somewhere between 4.8 and 9.6 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 situation. Our expertise demonstrates that as many people get away with it as those who don't. When deciding whether or not to risk it and simply top it up remember that it is the same thing as wagering it all on black - you have a 50/50 possibility of it working.
    3. Anything over 9.6 litres of Petrol in your Diesel G350 kurz really should straight away be removed since your probability of driving with this amount of contamination is in all likelihood less than one in fifty - definitely long odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you seen any kind of performance troubles after putting the incorrect fuel in your G350 kurz? If you have, have it removed regardless of the quantity of Petrol or the contamination ratio. Proceeding to drive running an automobile that is already beginning to suffer from the effects of wrong fuel contamination will likely end up in more and more damage affecting your fuel system parts.
  3. Are you interested in reassurance?
    In that case get it removed. Regardless of contamination percentage, there is inevitably some degree of danger in connection with operating a Diesel vehicle on Diesel contaminated with the incorrect fuel. Likely results of driving on the incorrect fuel normally include the motor 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 frequently seen Petrol in Diesel warning signs, and if you recognise any of them stop and get 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?


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.
