Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regular problem. And its remedy depends upon a number of things. Assuming you would like to know what you should do about it then stay with me.
Let us discuss the most important factors to take into account whenever making a decision whether or not to get a fuel drain:

  1. What level of Diesel did you put in to the Mercedes, considering that the fuel capacity of your Mercedes C230 is probably about 62 litres?
    1. A tiny quantity of Diesel, less than 3.1 litres of Diesel in a Petrol C230 will normally not necessarily be a massive problem. Experience has shown us that quantities under 3.1 litres (roughly 5% of the entire fuel tank volume) is often capable of being completely diluted through thoroughly topping up the tank with Petrol.
      It's relatively rare to encounter a car going through issues with less than 5% wrong fuel contamination. Please remember it is rare - definitely not impossible to find. There are actually a few motor vehicles that don't stand any level of contamination at all.
    2. Anywhere between 3.1 and 6.2 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 condition. Our working experience has confirmed that as many drivers get away with this as all those who don't. Any time you are figuring out whether to risk it and just simply top it up recognise that it is very much like gambling your car on black - you have a 50/50 chance of it working.
    3. Anything in excess of 6.2 litres of Diesel in a Petrol C230 really should straightaway be removed seeing as your likelihood of driving with that amount 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 seen any kind of performance troubles after putting the incorrect fuel in your C230? In that case, have it emptied regardless of the volume of Diesel or even the contamination percentage. Continually driving a vehicle that is now beginning to suffer from the effect of fuel contamination will probably definitely be responsible for progressively more damage affecting your fuel system.
  3. Do you need security?
    You should get it removed. Whatever the contamination percentage, there is invariably a certain level of danger affiliated with running a Petrol motor on Petrol contaminated with Diesel. Possible final outcomes of driving on the wrong fuel include things like the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, and the like. These are some of the most frequently seen Diesel in Petrol symptoms, and if you recognise any of them then stop and have it removed 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.
