Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a well-known mistake. And its remedy depends upon a variety of things. In the event that you would like to find out what you have to do about it then keep reading.
Listed below are the key factors to take into consideration whenever making a decision whether or not to have it drained:

  1. Exactly how much Diesel did you put in the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes A140 is most likely approximately 54 litres?
    1. A tiny quantity of Diesel, something like 2.7 litres of Diesel in a Petrol A140 will in most cases not necessarily be a major problem. Experience has demonstrated to us that quantities under 2.7 litres (which is about 5% of the entire fuel tank volume) is often able to be completely diluted by wholly filling up the rest of the tank with the correct fuel.
      It is pretty unusual to encounter a car experiencing issues due to less than 5% incorrect fuel contamination. Keep in mind that it's rare - not impossible to encounter. You can get some vehicles that won't stand any level of contamination whatsoever.
    2. Anywhere between 2.7 and 5.4 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 scenario. Our working experience has shown that as many drivers get away with this as all those who don't. Whenever figuring out whether to risk it and basically fill it up bear in mind that it is just like wagering it all on black - you have got a 50/50 chance of it being ok.
    3. Anything above 5.4 litres of Diesel in a Petrol A140 should really promptly be drained since your probability of succeeding with this amount of contamination is probably lower than one in 50 - extremely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you spotted any performance issues as a result of putting the wrong fuel in the A140? In that case, get it removed irrespective of the amount of Diesel or even the contamination ratio. Still running an automobile that is already beginning to suffer the effect of wrong fuel contamination can likely cause increasing amounts of damage being done to the fuel system parts.
  3. Do you need security?
    Then simply just get it emptied. No matter the contamination ratio, there is always a certain level of threat resulting from running a Petrol engine on fuel contaminated with Diesel. Possible results of driving on the incorrect fuel include the engine not starting, running unevenly, lack of power, wearing of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most common Diesel in Petrol signs or symptoms, and should you detect any of them then stop and get it removed right away.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
