Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a usual mistake. And what you need to do about it will depend on a variety of things. If perhaps you would like to know what you ought to do to fix it then keep reading.
Let us discuss the main variables to take into consideration when deciding whether to have a fuel drain:

  1. What amount of Diesel did you put in the Mercedes, taking into account that the fuel tank capacity of the Mercedes B180 is probably around 54 litres?
    1. A tiny quantity of Diesel, something like 2.7 litres of Diesel in a Petrol B180 will normally not necessarily be a big problem. Experience has taught us that an amount under 2.7 litres (roughly 5% of the whole fuel tank) is oftentimes capable of being adequately diluted simply by completely filling the tank with Petrol.
      It is relatively rare to come across a vehicle experiencing difficulties with under 5% incorrect fuel contamination. Remember that it is rare - definitely not impossible to find. There are actually some automobiles that will not endure any amount of fuel contamination in the slightest.
    2. In between 2.7 and 5.4 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 scenario. Our practical experience has shown that as many motorists get away with it as those who break down. When deciding whether or not to chance it and just fill it up recognise that it is very much like gambling your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything over 5.4 litres of Diesel in your Petrol B180 really should immediately be drained out as your likelihood of getting away with this quantity of contamination is in all likelihood lower than one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noticed any performance troubles after putting the bad fuel in the B180? In that case, have it emptied irrespective of the amount of Diesel or the contamination percentage. Continuing to drive driving a vehicle that is already beginning to suffer from the effects of fuel contamination will typically lead to more damage being caused to the fuel system.
  3. Are you interested in peace of mind?
    Then simply just get it emptied. Whatever the contamination ratio, there is invariably a certain level of threat linked with operating a Petrol vehicle on fuel contaminated with Diesel. Possible implications of driving on the wrong fuel normally include the engine refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are a few of the most common Diesel in Petrol signs or symptoms, and should you recognise any of them stop and get it removed immediately.

Refrain from getting any jack-of-all-trades to attend your vehicle. We are Mercedes experts and have got the qualifications and practical experience needed to ensure you get back on the road with minimum hassle or worry.

Diesel in Petrol FAQs

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

I put Diesel in a Petrol 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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
