Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a very common mistake. And what you should do about it depends upon a variety of factors. If perhaps you want to find out what it is advisable to do to fix it then read on.
Listed here the key factors to be aware of when making a decision whether to have a fuel drain:

  1. Exactly how much Petrol have you put into the Mercedes, bearing in mind that the fuel capacity of the Mercedes B220 CDI is most likely about 50 litres?
    1. A small amount of Petrol, something like 2.5 litres of Petrol in a Diesel B220 CDI will quite often not necessarily be a big problem. Experience has shown us that quantities less than 2.5 litres (approximately 5% of the overall fuel tank) is in many instances capable of being completely diluted by means of wholly topping the tank with Diesel.
      It is very unusual to encounter an automobile experiencing problems with less than 5% incorrect fuel contamination. Be aware that it's unusual - certainly not impossible to find. You will discover certain automobiles that won't endure any amount of contamination whatsoever.
    2. Anywhere between 2.5 and 5 litres of Petrol in the Mercedes (from 5 to 10%) is more of a 50/50 scenario. Our working experience has demonstrated that as many drivers get away with it as those who break down. Whenever deciding whether or not to risk it and basically top it up consider that it is the same thing as gambling everything on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 5 litres of Petrol in a Diesel B220 CDI should really right away be drained since your probability of driving with this level of contamination is undoubtedly lower than one in fifty - seriously huge odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you spotted any kind of performance issues as a result of putting the bad fuel in the B220 CDI? If you have, get it emptied no matter the amount of Petrol or the contamination ratio. Continually driving a motor vehicle that is currently starting to suffer the consequences of fuel contamination will probably only result in even more harm being done to your fuel system parts.
  3. Would you like assurance?
    Simply get it emptied. Whatever the contamination ratio, there is invariably some extent of risk connected with running a Diesel motor on Diesel contaminated with Petrol. Possible final outcomes of driving a car on the incorrect fuel can include the engine not starting, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are some of the most common Petrol in Diesel signs and symptoms, and should you detect any of them cease driving and have it removed as soon as possible.

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.
