Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regular error. And its remedy is determined by a few factors. Assuming you would like to know what you need to do to sort it out then continue reading.
Right here are the main variables to be aware of when figuring out 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 your Mercedes E50 AMG is in most cases approximately 80 litres?
    1. Hardly any Diesel, something like 4 litres of Diesel in a Petrol E50 AMG will more often than not not really be a huge problem. Experience has shown us that quantities under 4 litres (which is roughly 5% of the overall fuel tank capacity) is quite often able to be sufficiently diluted simply by completely topping up the remainder of the tank with Petrol.
      It is quite rare to encounter a car suffering from difficulties with under 5% wrong fuel contamination. Remember that it is very uncommon - certainly not impossible to encounter. There are some automobiles that don't endure any amount of contamination whatsoever.
    2. Somewhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 condition. Our working experience demonstrates that as many drivers get away with this as those people who don't. Any time you're deciding on whether to risk it and basically top it up remember that it is very much like gambling everything on black - you have got a 50/50 possibility of it working.
    3. Anything above 8 litres of Diesel in a Petrol E50 AMG ought to straightaway be drained since your probability of getting away with that amount of contamination is more than likely less than one in 50 - extremely huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any performance difficulties since putting the incorrect fuel in your E50 AMG? If so, get it removed no matter the quantity of Diesel or even the contamination ratio. Continuing to drive running a car that is beginning to suffer the effects of fuel contamination will only bring about more damage affecting your fuel system.
  3. Are you looking for peace of mind?
    Simply get it emptied. Regardless of the contamination percentage, there is inevitably some extent of risk associated with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Probable results of driving on the incorrect fuel normally include the motor refusing to start, running unevenly, losing power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are a few of the commonest Diesel in Petrol signs and symptoms, and if you observe any of them stop and get it drained asap.

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.
