Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a common mistake to make. And what you have to do about it is dependent upon various things. Assuming you would like to find out what you need to do about it then keep reading.
These are the most important variables to take into consideration whenever deciding whether or not to have a fuel drain:

  1. How much Diesel did you put into the Mercedes, considering that the fuel capacity of the Mercedes GL 450 is normally around 100 litres?
    1. A tiny amount of Diesel, something like 5 litres of Diesel in a Petrol GL 450 will normally not necessarily be a major problem. Experience has demonstrated to us that quantities under 5 litres (which is about 5% of the total fuel tank) is generally capable of being adequately diluted by thoroughly topping up the rest of the tank with the correct fuel.
      It is highly rare to come across an automobile suffering from issues due to under 5% wrong fuel contamination. Bear in mind that it is very unusual - in no way impossible to encounter. You will discover some cars that will not stand any level of fuel contamination at all.
    2. Between 5 and 10 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our working experience has shown us that as many motorists get away with it as those who don't. Any time you are deciding on whether or not to risk it and just top it up consider that it is exactly like wagering all of it on black - you have got a 50/50 possibility of it working.
    3. Anything above 10 litres of Diesel in a Petrol GL 450 ought to right away be drained seeing that your likelihood of getting away with this quantity of contamination is undoubtedly lower than one in fifty - genuinely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance concerns as a result of putting the bad fuel in the GL 450? In that case, get it emptied irrespective of the quantity of Diesel or the contamination percentage. Still driving a vehicle that is starting to suffer from the consequences of fuel contamination will likely cause more damage affecting the fuel system parts.
  3. Would you like peace of mind?
    Simply get it drained. Whatever the contamination ratio, there is always some extent of threat affiliated with operating a Petrol engine on Petrol contaminated with the wrong fuel. Likely final outcomes of driving on the incorrect fuel normally include the engine not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or bunged injectors, and so forth. These are some of the most typical Diesel in Petrol signs and symptoms, and if you recognise any of them stop and get it removed right now.

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.
