Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a fairly typical problem. And exactly what you need to do about it depends on a few things. In case you would like to know what you should do to sort it out then stay with me.
Listed below are the main variables to take into account when figuring out whether to have a fuel drain:

  1. How much Diesel have you put into the Mercedes, taking into account that the fuel tank capacity of the Mercedes G320 Cabrio is in most cases around 95 litres?
    1. A modest quantity of Diesel, as little as 4.75 litres of Diesel in a Petrol G320 Cabrio will in most cases not really be a significant problem. Experience has demonstrated to us that quantities under 4.75 litres (which is 5% of the total fuel tank capacity) is frequently capable of being completely diluted simply by wholly topping up the rest of the tank with Petrol.
      It is very uncommon to encounter a car or truck having problems because of below 5% wrong fuel contamination. Remember that it is very unusual - in no way impossible to find. There are actually a few automobiles that won't endure any level of contamination whatsoever.
    2. In between 4.75 and 9.5 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 scenario. Our practical experience demonstrates that as many people get away with this as those people who don't. When you are figuring out whether or not to chance it and simply top it up remember that it is very much like gambling all of it on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 9.5 litres of Diesel in a Petrol G320 Cabrio really should promptly be removed since your likelihood of getting away with that level of contamination is more than likely below one in fifty - extremely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any performance issues since putting the incorrect fuel in your G320 Cabrio? If so, have it emptied no matter the quantity of Diesel or even the contamination ratio. Proceeding to run running an automobile that is starting to suffer from the effects of fuel contamination can just be responsible for increasing amounts of harm affecting the fuel system parts.
  3. Do you want peace of mind?
    Simply get it drained. No matter the contamination percentage, there is invariably some extent of danger caused by running a Petrol motor on Petrol contaminated with the incorrect fuel. Probable results of driving a vehicle on the incorrect fuel normally include the motor refusing to start, running unevenly, losing power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you detect any of them then cease driving and have it removed asap.

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?


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?


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?


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 Petrol 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.
