Mercedes Fuel Drain

ABOUT

Filling Petrol in a Diesel Mercedes is a common mistake. And its remedy varies according to a few things. If you would like to know what to do about it then please read on.
Right here are the key factors to think about whenever deciding whether or not to get a fuel drain:

  1. What level of Petrol did you put into the Mercedes, taking into account that the fuel tank capacity of your Mercedes B180 CDI is most likely around 54 litres?
    1. Hardly any Petrol, something like 2.7 litres of Petrol in a Diesel B180 CDI will most of the time not be a huge problem. Experience has taught us that quantities under 2.7 litres (5% of the entire fuel tank capacity) is usually able to be adequately diluted by thoroughly topping the tank with the appropriate fuel.
      It's extremely uncommon to come across a car or truck suffering from problems with below 5% incorrect fuel contamination. Remember that it's uncommon - certainly not impossible to encounter. You will discover a number of motor vehicles that don't endure any amount of contamination in the slightest.
    2. Anywhere between 2.7 and 5.4 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 situation. Our experience has confirmed that as many people get away with this as all those who break down. Any time you're figuring out whether or not to risk it and just simply top it up recognise that it is exactly like betting it all on black - you've got a 50/50 possibility of it working out.
    3. Anything over 5.4 litres of Petrol in your Diesel B180 CDI should really immediately be drained out seeing as your likelihood of getting away with this amount of contamination is more than likely less than one in fifty - really huge odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you noticed any performance issues since putting the bad fuel in your B180 CDI? If you have, have it removed regardless of the volume of Petrol or even the contamination percentage. Still driving a car that is already beginning to suffer the effects of fuel contamination can only lead to even more harm affecting your fuel system parts.
  3. Do you want assurance?
    Then get it drained. No matter the contamination percentage, there is always some extent of risk in connection with operating a Diesel engine on fuel contaminated with the incorrect fuel. Possible outcomes of driving a vehicle on the incorrect fuel include things like the engine refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, damaged or blocked injectors, and so on. These are some of the most typical Petrol in Diesel warning signs, and in the event that you detect any of them cease driving and get it drained immediately.

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.
