Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a well-known mistake. And its solution varies according to a few factors. If perhaps you would like to find out what it is best to do to sort it out then continue reading.
Let us discuss the most crucial variables to keep in mind whenever determining whether or not to have it drained:

  1. Exactly how much Diesel did you put in to the Mercedes, considering that the fuel tank capacity of your Mercedes CLA 180 is normally around 50 litres?
    1. A small amount of Diesel, as little as 2.5 litres of Diesel in a Petrol CLA 180 will generally not really be a major problem. Experience has shown us that an amount under 2.5 litres (almost 5% of the entire fuel tank volume) is frequently able to be adequately diluted by completely filling up the rest of the tank with Petrol.
      It's quite uncommon to come across a motor vehicle going through issues because of less than 5% incorrect fuel contamination. Bear in mind that it is unusual - definitely not impossible to find. You will discover a number of motor vehicles that will not stand any quantity of fuel contamination in the slightest.
    2. Anywhere between 2.5 and 5 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 scenario. Our working experience has shown us that as many people get away with this as those people who break down. Whenever you are figuring out whether to risk it and just top it up bear in mind that it is the same thing as betting it all on black - you've got a 50/50 chance of it working out.
    3. Anything more than 5 litres of Diesel in your Petrol CLA 180 must straight away be removed seeing that your probability of getting away with this level of contamination is very likely below one in fifty - truly long odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you spotted any performance difficulties since putting the incorrect fuel in your CLA 180? If you have, have it drained regardless of the quantity of Diesel or even the contamination ratio. Continually driving a vehicle that is currently starting to suffer from the consequences of wrong fuel contamination will just lead to more and more damage being caused to your fuel system parts.
  3. Are you looking for assurance?
    In that case get it removed. Regardless of the contamination percentage, there is invariably some degree of risk in connection with driving a Petrol vehicle on fuel contaminated with Diesel. Probable implications of driving on the incorrect fuel normally include the motor not starting, running lumpy, reduced power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are a few of the most typical Diesel in Petrol warning signs, and in the event that you detect any of them then cease driving and get it drained immediately.

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.
