Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a regularly occurring mistake to make. And exactly what you want to do about it is determined by a few things. If perhaps you would like to know what you must do about this then continue reading.
Right here are the most crucial factors to think about when deciding whether to get a fuel drain:

  1. What level of Diesel did you put in the Mercedes, considering that the fuel capacity of the Mercedes E320 is most likely around 80 litres?
    1. A tiny quantity of Diesel, as little as 4 litres of Diesel in a Petrol E320 will usually not be a big problem. Experience has proven to us that quantities less than 4 litres (which is roughly 5% of the whole fuel tank) is quite often capable of being adequately diluted through wholly topping up the tank with the correct fuel.
      It's highly unusual to come across an automobile going through difficulties due to under 5% wrong fuel contamination. Keep in mind that it is very infrequently found - definitely not impossible to find. There are actually certain cars that will not endure any degree of fuel contamination in the slightest.
    2. In between 4 and 8 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 situation. Our expertise has revealed that as many people get away with it as those people who break down. Whenever you are deciding on whether or not to risk it and basically top it up remember that it is exactly like wagering it all on black - you've got a 50/50 chance of it being ok.
    3. Anything in excess of 8 litres of Diesel in your Petrol E320 must promptly be removed seeing as your probability of driving with this level of contamination is probably lower than one in fifty - really huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any performance difficulties as a result of putting the wrong fuel in the E320? If you have, have it removed no matter the quantity of Diesel or even the contamination percentage. Continually driving a car that is currently beginning to suffer the effect of fuel contamination will probably definitely be responsible for increasing amounts of damage being done to your fuel system parts.
  3. Are you looking for assurance?
    In that case get it emptied. Regardless of contamination percentage, there is inevitably some degree of threat resulting from operating a Petrol motor on fuel contaminated with Diesel. Possible results of driving a vehicle on the wrong fuel include the motor refusing to start, running unevenly, loss in power, wearing of the high-pressure pump, worn or clogged injectors, etc. These are some of the most common Diesel in Petrol signs or symptoms, and if you detect any of them stop and get it removed asap.

Diesel in Petrol Questions

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.
