Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regular mistake. And its solution is dependent upon several different factors. In case you want to find out what you ought to do about this then please read on.
Right here are the most important variables to keep in mind whenever deciding on whether or not to get a fuel drain:

  1. What amount of Diesel did you put into the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes A210 Evolution is most likely about 54 litres?
    1. Hardly any Diesel, less than 2.7 litres of Diesel in a Petrol A210 Evolution will quite often not necessarily be a big problem. Experience has demonstrated to us that quantities less than 2.7 litres (which is approximately 5% of the overall fuel tank volume) is generally capable of being adequately diluted by means of totally topping the tank with the appropriate fuel.
      It's quite rare to encounter a car or truck having difficulties with under 5% wrong fuel contamination. Remember that it is very unusual - certainly not impossible to encounter. There are some motor vehicles that will not stand any quantity of fuel contamination whatsoever.
    2. Anywhere between 2.7 and 5.4 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 situation. Our expertise has shown us that as many people get away with it as those who don't. When trying to decide whether or not to risk it and basically fill it up consider that it is very much like wagering it all on black - you've got a 50/50 chance of it working.
    3. Anything in excess of 5.4 litres of Diesel in your Petrol A210 Evolution really should straightaway be drained out seeing as your probability of getting away with that level of contamination is probably lower than one in fifty - definitely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any kind of performance difficulties after putting the wrong fuel in the A210 Evolution? If so, have it emptied irrespective of the quantity of Diesel or even the contamination ratio. Continuing to run driving a vehicle that is currently starting to suffer the effects of wrong fuel contamination will just be responsible for progressively more damage being done to your fuel system.
  3. Are you interested in security?
    Then simply just get it removed. Whatever the contamination ratio, there is invariably a certain level of threat caused by operating a Petrol engine on fuel contaminated with Diesel. Likely implications of driving on the incorrect fuel include the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are some of the most frequently seen Diesel in Petrol warning signs, and in the event that you observe any of them then stop driving and have it removed right now.

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.
