Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a fairly typical mistake to make. And its solution will depend on a variety of things. If perhaps you would like to find out what you need to do about this then keep on reading.
Right here are the key variables to keep in mind when figuring out whether to have a fuel drain:

  1. Exactly how much Diesel did you put in to the Mercedes, taking into account that the fuel tank capacity of your Mercedes GL 63 AMG is in most cases roughly 100 litres?
    1. A tiny quantity of Diesel, less than 5 litres of Diesel in a Petrol GL 63 AMG will generally not necessarily be a significant problem. Experience has proven to us that anything less than 5 litres (5% of the fuel tank) is in many instances able to be sufficiently diluted by wholly filling the tank with the correct fuel.
      It is pretty uncommon to come across an automobile experiencing issues because of less than 5% wrong fuel contamination. Be aware that it's unusual - not impossible to find. You can get some vehicles that won't stand any quantity of fuel contamination at all.
    2. Anywhere between 5 and 10 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 scenario. Our practical experience has revealed that as many motorists get away with it as those who don't. When you are deciding whether or not to chance it and basically fill it up consider that it is much like wagering it all on black - you have a 50/50 possibility of it working out.
    3. Anything over 10 litres of Diesel in a Petrol GL 63 AMG really should promptly be drained out seeing that your likelihood of driving with that amount of contamination is almost certainly below one in fifty - genuinely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any kind of performance problems ever since putting the bad fuel in the GL 63 AMG? If you have, get it drained irrespective of the quantity of Diesel or the contamination ratio. Continuing to drive driving an automobile that is now beginning to suffer the effect of wrong fuel contamination will only cause more damage being caused to your fuel system parts.
  3. Do you want security?
    Then get it drained. No matter the contamination ratio, there is invariably some extent of risk affiliated with running a Petrol vehicle on fuel contaminated with Diesel. Likely consequences of driving on the wrong fuel normally include the engine not starting, running unevenly, reduced power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol signs or symptoms, and in the event that you observe any of them then stop and get it removed 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?


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.
