Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a fairly typical error. And exactly what you should do about it is based on a variety of factors. In the event that you would like to know what you must do about this then read on.
Listed here are the most crucial variables to think about when choosing whether or not to get a fuel drain:

  1. What level of Diesel have you put in the Mercedes, taking into account that the fuel tank capacity of your Mercedes E55 AMG is normally about 80 litres?
    1. Hardly any Diesel, something like 4 litres of Diesel in a Petrol E55 AMG will typically not necessarily be a major problem. Experience has taught us that anything less than 4 litres (approximately 5% of the fuel tank volume) is oftentimes capable of being sufficiently diluted through completely topping up the remainder of the tank with Petrol.
      It is relatively rare to encounter an automobile having issues because of lower than 5% incorrect fuel contamination. Bear in mind that it's infrequent - definitely not impossible to find. There are actually certain automobiles that won't endure any amount of contamination at all.
    2. In between 4 and 8 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our experience has proven that as many motorists get away with it as all those who don't. Any time you're deciding upon whether to chance it and basically fill it up bear in mind that it is just like gambling everything on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 8 litres of Diesel in a Petrol E55 AMG really should promptly be drained out seeing that your probability of getting away with this amount of contamination is in all likelihood below one in 50 - definitely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance issues after putting the bad fuel in your E55 AMG? In that case, have it drained regardless of the volume of Diesel or the contamination percentage. Continually driving a car that is already beginning to suffer from the effect of wrong fuel contamination will definitely end up in increasing amounts of damage being done to your fuel system components.
  3. Are you interested in peace of mind?
    Then simply just get it removed. Regardless of the contamination ratio, there is invariably some extent of danger associated with driving a Petrol motor on fuel contaminated with Diesel. Possible consequences of driving a vehicle on the wrong fuel include the engine refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the commonest Diesel in Petrol signs or symptoms, and should you notice any of them stop and have it removed right now.

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.
