Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a usual mistake to make. And exactly what you need to do about it is based on an assortment of factors. In case you want to know what you ought to do about it then please read on.
Here are the main factors to think about when determining whether to have a fuel drain:

  1. How much Diesel did you put in to the Mercedes, taking into account that the fuel tank capacity of the Mercedes S600 Coupe is in most cases approximately 100 litres?
    1. A modest quantity of Diesel, something like 5 litres of Diesel in a Petrol S600 Coupe will normally not really be a big problem. Experience has shown us that anything under 5 litres (5% of the overall fuel tank) is very often able to be completely diluted through completely filling up the tank with the correct fuel.
      It is rather rare to find an automobile having issues with under 5% wrong fuel contamination. Keep in mind that it is very uncommon - not impossible to encounter. There are a few motor vehicles that won't endure any amount of contamination whatsoever.
    2. Between 5 and 10 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 situation. Our practical experience demonstrates that as many people get away with it as those who break down. Whenever you are deciding on whether to risk it and just top it up recognise that it is just like wagering everything on black - you will have a 50/50 chance of it working.
    3. Anything above 10 litres of Diesel in a Petrol S600 Coupe must straight away be drained out as your likelihood of succeeding with that amount of contamination is in all likelihood below one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any performance concerns since putting the bad fuel in the S600 Coupe? If you have, have it removed irrespective of the quantity of Diesel or the contamination ratio. Continually running a car that is currently beginning to suffer the effects of fuel contamination will probably just end up in more and more damage being caused to the fuel system components.
  3. Do you want peace of mind?
    You should get it drained. Whatever the contamination percentage, there is inevitably some extent of danger connected to driving a Petrol motor on fuel contaminated with Diesel. Likely outcomes of driving on the incorrect fuel include things like the engine not starting, running lumpy, losing power, wearing of the high-pressure pump, damaged or blocked injectors, and the like. These are a few of the most common Diesel in Petrol signs and symptoms, and in the event that you notice any of them then stop and have 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.
