Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a usual error. And its remedy is based on a few things. In case you would like to know what you ought to do to fix it then keep reading.
Listed below are the most crucial variables to consider whenever determining whether to get a fuel drain:

  1. Exactly how much Diesel did you put in the Mercedes, considering that the fuel tank capacity of the Mercedes CLC 230 is most likely roughly 62 litres?
    1. A modest amount of Diesel, something like 3.1 litres of Diesel in a Petrol CLC 230 will more often than not not really be a massive problem. Experience has demonstrated to us that anything under 3.1 litres (which is approximately 5% of the total fuel tank) is in many instances able to be adequately diluted by wholly topping the tank with Petrol.
      It is pretty rare to find a vehicle suffering from problems due to under 5% wrong fuel contamination. Keep in mind that it is very rare - definitely not impossible to find. You can get a few motor vehicles that won't stand any degree of fuel contamination whatsoever.
    2. In between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our working experience has demonstrated that as many people get away with it as all those who don't. When you are deciding upon whether or not to risk it and simply fill it up consider that it is much like gambling everything on black - you have got a 50/50 possibility of it working.
    3. Anything in excess of 6.2 litres of Diesel in a Petrol CLC 230 must straightaway be drained out since your probability of succeeding with this quantity of contamination is in all likelihood less than one in fifty - seriously big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance difficulties after putting the incorrect fuel in the CLC 230? In that case, have it drained no matter the quantity of Diesel or even the contamination ratio. Still running a motor vehicle that is already starting to suffer the effects of fuel contamination will probably just end up in progressively more damage being done to the fuel system parts.
  3. Are you interested in assurance?
    Then get it removed. Regardless of the contamination ratio, there is inevitably a certain level of threat caused by running a Petrol motor on fuel contaminated with the incorrect fuel. Likely outcomes of driving on the wrong fuel normally include the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, damaged or blocked injectors, and so forth. These are a few of the most typical Diesel in Petrol warning signs, and if you observe any of them then stop and get it removed as soon as possible.

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.
