Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a fairly typical error. And its remedy depends upon a variety of things. Assuming you would like to find out what it is advisable to do to fix it then please read on.
These are the most crucial factors to keep in mind whenever determining whether to get a fuel drain:

  1. What amount of Diesel did you put in to the Mercedes, bearing in mind that the fuel capacity of your Mercedes GL 500 is most likely roughly 100 litres?
    1. A small quantity of Diesel, as little as 5 litres of Diesel in a Petrol GL 500 will most of the time not be a huge problem. Experience has shown us that anything less than 5 litres (roughly 5% of the overall fuel tank) is often able to be completely diluted by totally topping up the remainder of the tank with the right fuel.
      It is quite uncommon to find a car or truck having difficulties because of below 5% wrong fuel contamination. Remember that it is very infrequently found - not impossible to find. You will discover a number of cars that won't endure any amount of fuel contamination whatsoever.
    2. Between 5 and 10 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our expertise demonstrates that as many motorists get away with it as those people who break down. Whenever you are deciding upon whether to chance it and basically top it up consider that it is very much like wagering your car on black - you've got a 50/50 chance of it working.
    3. Anything more than 10 litres of Diesel in a Petrol GL 500 must right away be drained as your probability of succeeding with this quantity of contamination is in all likelihood lower than one in 50 - truly long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you observed any performance concerns as a result of putting the incorrect fuel in your GL 500? In that case, have it emptied irrespective of the volume of Diesel or even the contamination ratio. Continually driving an automobile that is currently starting to suffer from the effect of wrong fuel contamination will probably definitely result in increasing amounts of harm affecting the fuel system.
  3. Would you like peace of mind?
    In that case get it drained. Regardless of the contamination percentage, there is invariably a certain level of danger connected with operating a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely implications of driving a vehicle on the incorrect fuel include things like the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or clogged injectors, and the like. These are several of the commonest Diesel in Petrol signs and symptoms, and should you observe any of them then stop driving and get it drained right away.

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?


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?


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?


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?


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?


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?


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.
