Mercedes Fuel Drain

ABOUT

Filling up with Petrol in a Diesel Mercedes is a usual error. And exactly what you have to do about it is based on a number of things. If perhaps you would like to find out what you ought to do about this then stay with me.
Listed here are the key variables to take into consideration when choosing whether to get a fuel drain:

  1. How much Petrol did you put into the Mercedes, keeping in mind that the fuel capacity of your Mercedes E400 CDI is usually approximately 80 litres?
    1. A tiny quantity of Petrol, less than 4 litres of Petrol in a Diesel E400 CDI will more often than not not be a massive problem. Experience has demonstrated to us that anything less than 4 litres (roughly 5% of the entire fuel tank volume) is in many instances able to be completely diluted simply by thoroughly filling the rest of the tank with Diesel.
      It is very uncommon to come across an automobile having difficulties with under 5% incorrect fuel contamination. Please remember it is very uncommon - definitely not impossible to encounter. You will discover a few automobiles that don't endure any degree of contamination at all.
    2. In between 4 and 8 litres of Petrol in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our practical experience has proven that as many motorists get away with it as those people who don't. Whenever deciding upon whether to chance it and simply top it up remember that it is the same as gambling all of it on black - you have got a 50/50 chance of it working.
    3. Anything in excess of 8 litres of Petrol in your Diesel E400 CDI should really right away be drained out because your probability of driving with that amount of contamination is in all likelihood less than one in fifty - definitely big odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you observed any kind of performance concerns since putting the wrong fuel in the E400 CDI? If so, get it drained regardless of the volume of Petrol or the contamination ratio. Continually driving a car that is now beginning to suffer the consequences of fuel contamination will probably just cause increasing amounts of harm affecting your fuel system parts.
  3. Do you need assurance?
    In that case get it drained. Regardless of the contamination percentage, there is always some amount of risk resulting from operating a Diesel engine on fuel contaminated with Petrol. Probable final outcomes of driving on the wrong fuel normally include the engine refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are several of the most typical Petrol in Diesel signs and symptoms, and in the event that you observe any of them then stop driving and have it removed asap.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

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 Diesel car on Petrol cause damage to it?

Answer

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 Petrol can I get away with in a Diesel car?

Answer

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?

Answer

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?

Answer

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 Diesel and add some 2-stroke oil?

Answer

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.
