Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a well-known mistake to make. And its remedy hinges on various things. If you would like to know what you must do about it then continue reading.
Let us discuss the most important factors to consider when figuring out whether or not to have a fuel drain:

  1. What amount of Diesel have you put in to the Mercedes, considering that the fuel capacity of the Mercedes CLS 500 is in most cases approximately 80 litres?
    1. A modest quantity of Diesel, less than 4 litres of Diesel in a Petrol CLS 500 will in most cases not really be a big problem. Experience has demonstrated to us that quantities under 4 litres (which is almost 5% of the entire fuel tank capacity) is generally able to be adequately diluted by means of totally topping the remainder of the tank with the right fuel.
      It's quite uncommon to come across an automobile going through difficulties with under 5% wrong fuel contamination. Please remember it is infrequently found - in no way impossible to find. There are actually a few automobiles that won't stand any level of contamination at all.
    2. Anywhere between 4 and 8 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 scenario. Our expertise has demonstrated that as many drivers get away with this as all those who break down. Any time you're figuring out whether or not to risk it and basically top it up remember that it is the same thing as betting it all on black - you have got a 50/50 possibility of it working.
    3. Anything over 8 litres of Diesel in a Petrol CLS 500 should really as soon as possible be drained as your likelihood of driving with that quantity of contamination is undoubtedly lower than one in 50 - seriously long odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you seen any performance concerns ever since putting the bad fuel in your CLS 500? If that's the case, have it emptied no matter the volume of Diesel or the contamination percentage. Continually driving a vehicle that is currently beginning to suffer the consequences of fuel contamination will likely result in more and more harm affecting your fuel system components.
  3. Do you want reassurance?
    Simply get it drained. No matter the contamination percentage, there is invariably a certain level of danger connected with driving a Petrol vehicle on fuel contaminated with the incorrect fuel. Probable implications of driving on the incorrect fuel normally include the motor not starting, running lumpy, lack of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the commonest Diesel in Petrol warning signs, and if you recognise any of them stop and get it drained right now.

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.
