Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a common mistake to make. And its solution is based on several factors. In case you want to find out what you ought to do about it then keep reading.
Listed here the most crucial factors to take into consideration when choosing whether or not to get it drained:

  1. What level of Petrol have you put in the Mercedes, taking into account that the fuel capacity of your Mercedes G320 CDI Cabrio is normally roughly 96 litres?
    1. Hardly any Petrol, less than 4.8 litres of Petrol in a Diesel G320 CDI Cabrio will usually not be a huge problem. Experience has demonstrated to us that an amount less than 4.8 litres (which is close to 5% of the total fuel tank) is frequently capable of being adequately diluted by means of entirely filling the remainder of the tank with Diesel.
      It is pretty rare to find a vehicle suffering from problems because of below 5% incorrect fuel contamination. Remember that it is infrequently found - in no way impossible to encounter. You can get a few motor vehicles that don't endure any quantity 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 has proven that as many drivers get away with this as those who don't. When deciding on whether to chance it and just simply fill it up consider that it is exactly like wagering your car on black - you have a 50/50 chance of it working.
    3. Anything more than 9.6 litres of Petrol in a Diesel G320 CDI Cabrio should really promptly be drained out as your likelihood of driving with that amount of contamination is more than likely lower than one in fifty - seriously huge odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you seen any kind of performance difficulties ever since putting the wrong fuel in your G320 CDI Cabrio? In that case, get it removed regardless of the volume of Petrol or the contamination percentage. Continually driving an automobile that is beginning to suffer the consequences of fuel contamination can likely bring about even more damage being caused to your fuel system parts.
  3. Do you need security?
    Then simply just get it drained. Regardless of the contamination ratio, there is always a certain level of threat caused by operating a Diesel engine on fuel contaminated with Petrol. Possible consequences of driving a vehicle on the incorrect fuel normally include the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are a few of the most frequently seen Petrol in Diesel symptoms, and should you notice any of them then stop driving and get it drained 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.
