Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a fairly typical error. And its solution hinges on various things. In case you want to find out what you have to do about it then continue reading.
Right here are the most important factors to to consider when deciding whether or not to have the car drained:

  1. Exactly how much Diesel have you put in to the Mercedes, considering that the fuel tank capacity of your Mercedes R63 AMG is in most cases roughly 80 litres?
    1. A tiny quantity of Diesel, less than 4 litres of Diesel in a Petrol R63 AMG will typically not be a huge problem. Experience has taught us that anything under 4 litres (about 5% of the entire fuel tank) is in many instances able to be sufficiently diluted through totally topping the remainder of the tank with the right fuel.
      It is relatively rare to encounter a motor vehicle going through problems due to lower than 5% incorrect fuel contamination. Keep in mind it is rare - in no way impossible to find. There are a number of motor vehicles that won't endure any degree of fuel contamination whatsoever.
    2. In between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our experience has demonstrated that as many motorists get away with this as those people who don't. Whenever trying to decide whether to chance it and just top it up consider that it is much like betting everything on black - you have a 50/50 chance of it working.
    3. Anything above 8 litres of Diesel in your Petrol R63 AMG ought to straight away be drained because your probability of getting away with that level of contamination is certainly less than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any kind of performance difficulties as a result of putting the bad fuel in your R63 AMG? In that case, get it drained regardless of the quantity of Diesel or even the contamination ratio. Still running a motor vehicle that is already starting to suffer the effect of fuel contamination will likely be responsible for even more damage affecting your fuel system.
  3. Would you like reassurance?
    Simply get it removed. Whatever the contamination ratio, there is always some extent of risk associated with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Possible consequences of driving a car on the wrong fuel normally include the motor refusing to start, running lumpy, loss of power, wearing of the high-pressure pump, worn or clogged injectors, and so forth. These are some of the most common Diesel in Petrol signs and symptoms, and if you observe any of them stop and get it drained immediately.

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.
