Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a fairly typical mistake to make. And its remedy varies according to various things. Assuming you want to know what you need to do to sort it out then stay with me.
Right here are the most crucial factors to think about when determining whether to get your car drained:

  1. How much Diesel have you put in to the Mercedes, taking into account that the fuel capacity of your Mercedes Viano 3.0 Extra Long is normally around 75 litres?
    1. A small quantity of Diesel, something like 3.75 litres of Diesel in a Petrol Viano 3.0 Extra Long will most of the time not necessarily be a major problem. Experience has shown us that quantities less than 3.75 litres (close to 5% of the whole fuel tank capacity) is usually able to be adequately diluted simply by completely filling up the rest of the tank with Petrol.
      It is extremely rare to come across a car suffering from difficulties with under 5% wrong fuel contamination. Be aware that it's uncommon - certainly not impossible to encounter. You can get some cars that don't endure any quantity of fuel contamination whatsoever.
    2. In between 3.75 and 7.5 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our practical experience has demonstrated that as many people get away with it as all those who break down. When you are deciding whether or not to chance it and simply top it up bear in mind that it is very much like gambling all of it on black - you have a 50/50 possibility of it being ok.
    3. Anything in excess of 7.5 litres of Diesel in your Petrol Viano 3.0 Extra Long really should promptly be removed since your likelihood of succeeding with this quantity of contamination is very likely below one in fifty - definitely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you detected any performance issues ever since putting the bad fuel in your Viano 3.0 Extra Long? In that case, get it emptied irrespective of the quantity of Diesel or even the contamination percentage. Still driving a motor vehicle that is currently beginning to suffer the consequences of fuel contamination will just lead to increasing amounts of harm affecting your fuel system parts.
  3. Do you want assurance?
    Simply get it drained. No matter the contamination ratio, there is inevitably some amount of risk in connection with operating a Petrol motor on fuel contaminated with Diesel. Possible results of driving a car on the wrong fuel can include the engine not starting, running unevenly, decrease in power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and if you recognise any of them stop driving and get it removed right now.

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.

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.

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."

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.
