Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a very common mistake to make. And its solution is based on several factors. In the event that you want to know what to do about it then keep on reading.
Listed below are the most crucial factors to think about when deciding on whether to get a fuel drain:

  1. What level of Petrol did you put in to the Mercedes, taking into consideration that the fuel capacity of your Mercedes A170 CDI is usually roughly 54 litres?
    1. A tiny amount of Petrol, less than 2.7 litres of Petrol in a Diesel A170 CDI will normally not be a huge problem. Experience has proven to us that an amount under 2.7 litres (which is 5% of the entire fuel tank) is quite often capable of being completely diluted by wholly topping the tank with Diesel.
      It is very unusual to come across a car or truck going through issues because of below 5% incorrect fuel contamination. Keep in mind it is very uncommon - definitely not impossible to find. There are actually certain motor vehicles that don't stand any quantity of contamination in the slightest.
    2. Somewhere between 2.7 and 5.4 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 condition. Our experience has confirmed that as many motorists get away with it as those who don't. When deciding on whether or not to risk it and simply fill it up remember that it is much like betting everything on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 5.4 litres of Petrol in your Diesel A170 CDI must immediately be removed since your probability of driving with that quantity of contamination is almost certainly lower than one in fifty - genuinely huge odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you noticed any kind of performance troubles ever since putting the wrong fuel in the A170 CDI? If so, get it drained irrespective of the volume of Petrol or the contamination ratio. Continuing to drive driving a car that is now starting to suffer the effect of wrong fuel contamination will definitely lead to even more damage affecting the fuel system.
  3. Do you need reassurance?
    In that case get it removed. Regardless of the contamination ratio, there is invariably some amount of risk connected to driving a Diesel engine on Diesel contaminated with the incorrect fuel. Possible consequences of driving on the wrong fuel include things like the engine not starting, running unevenly, loss in power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are some of the commonest Petrol in Diesel signs and symptoms, and should you observe any of them stop driving and have it drained right away.

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.
