Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a common mistake. And its remedy hinges on a few factors. In the event that you would like to know what you should do about this then please read on.
Let us discuss the key factors to keep in mind whenever deciding on whether or not to have a fuel drain:

  1. How much Diesel have you put into the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes CLC 180 is most likely around 62 litres?
    1. Hardly any Diesel, less than 3.1 litres of Diesel in a Petrol CLC 180 will in most situations not really be a huge problem. Experience has proven to us that quantities under 3.1 litres (close to 5% of the total fuel tank capacity) is frequently capable of being adequately diluted by completely topping up the remainder of the tank with the correct fuel.
      It's extremely uncommon to find an automobile experiencing problems with below 5% incorrect fuel contamination. Keep in mind it is very rare - definitely not impossible to find. There are actually a few motor vehicles that will not endure any degree of fuel contamination in the slightest.
    2. Between 3.1 and 6.2 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 condition. Our working experience has demonstrated that as many motorists get away with it as those people who don't. When figuring out whether or not to chance it and simply top it up bear in mind that it is exactly like wagering your car on black - you have a 50/50 possibility of it working out.
    3. Anything in excess of 6.2 litres of Diesel in a Petrol CLC 180 really should as soon as possible be removed as your likelihood of getting away with that amount of contamination is certainly below one in fifty - definitely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance troubles ever since putting the bad fuel in your CLC 180? If you have, have it emptied no matter the amount of Diesel or even the contamination percentage. Continually driving a car that is now starting to suffer from the consequences of fuel contamination will probably likely result in more and more harm affecting the fuel system parts.
  3. Do you need assurance?
    Simply get it emptied. Regardless of the contamination percentage, there is always some degree of risk connected to operating a Petrol motor on fuel contaminated with the wrong fuel. Possible final outcomes of driving a car on the incorrect fuel normally include the motor refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, damaged or blocked injectors, and so on. These are some of the commonest Diesel in Petrol signs or symptoms, and if you recognise any of them then cease driving and have it drained 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.
