Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a usual mistake to make. And its solution is based on an assortment of things. Assuming you would like to find out what you ought to do to sort it out then read on.
Let us discuss the most important variables to keep in mind whenever choosing whether to have a fuel drain:

  1. What level of Diesel did you put in the Mercedes, taking into consideration that the fuel capacity of your Mercedes B150 is normally around 54 litres?
    1. A small quantity of Diesel, less than 2.7 litres of Diesel in a Petrol B150 will usually not really be a major problem. Experience has demonstrated to us that quantities less than 2.7 litres (close to 5% of the fuel tank volume) is very often capable of being sufficiently diluted simply by completely topping the remainder of the tank with Petrol.
      It's pretty unusual to encounter a car having difficulties because of less than 5% incorrect fuel contamination. Remember that it is uncommon - not impossible to encounter. There are a few motor vehicles that don't stand any level of contamination whatsoever.
    2. Anywhere between 2.7 and 5.4 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 scenario. Our practical experience has shown us that as many people get away with this as all those who break down. Any time you are figuring out whether or not to risk it and simply fill it up recognise that it is just like gambling your car on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 5.4 litres of Diesel in a Petrol B150 really should immediately be drained out seeing that your probability of succeeding with that quantity of contamination is more than likely below one in 50 - really long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any kind of performance concerns since putting the bad fuel in the B150? In that case, get it removed no matter the quantity of Diesel or even the contamination percentage. Continually driving an automobile that is now starting to suffer from the consequences of wrong fuel contamination will probably just cause increasing amounts of damage affecting the fuel system components.
  3. Are you looking for reassurance?
    In that case get it emptied. Regardless of the contamination percentage, there is always some amount of risk connected to driving a Petrol engine on fuel contaminated with the incorrect fuel. Likely implications of driving on the wrong fuel include things like the motor refusing to start, running lumpy, lack of power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and should you recognise any of them stop driving and get it drained right now.

Diesel in Petrol Questions

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.
