Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a usual mistake. And what you need to do about it is determined by several factors. In case you want to know what it is best to do about it then please read on.
Right here are the most important factors to take into consideration whenever deciding on whether or not to have a fuel drain:

  1. What level of Petrol have you put into the Mercedes, taking into consideration that the fuel tank capacity of your Mercedes CLC 200 CDI is usually roughly 62 litres?
    1. Hardly any Petrol, as little as 3.1 litres of Petrol in a Diesel CLC 200 CDI will typically not really be a major problem. Experience has demonstrated to us that quantities under 3.1 litres (5% of the whole fuel tank volume) is often able to be adequately diluted by thoroughly topping up the tank with the appropriate fuel.
      It is rather rare to encounter a vehicle suffering from difficulties due to below 5% wrong fuel contamination. Bear in mind that it is very infrequent - definitely not impossible to encounter. You will discover some cars that won't endure any degree of fuel contamination at all.
    2. Somewhere between 3.1 and 6.2 litres of Petrol in the Mercedes (from 5 to 10%) is a 50/50 condition. Our expertise demonstrates that as many drivers get away with it as those people who break down. Any time you are deciding whether to risk it and just simply fill it up bear in mind that it is very much like gambling it all on black - you have got a 50/50 chance of it being ok.
    3. Anything above 6.2 litres of Petrol in your Diesel CLC 200 CDI ought to right away be drained out since your likelihood of driving with this amount of contamination is certainly less than one in fifty - extremely long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you seen any performance troubles since putting the bad fuel in the CLC 200 CDI? In that case, get it drained irrespective of the amount of Petrol or the contamination percentage. Still driving an automobile that is currently starting to suffer the consequences of wrong fuel contamination will definitely be responsible for even more damage being caused to the fuel system.
  3. Are you interested in security?
    In that case get it drained. No matter the contamination percentage, there is always some amount of risk in connection with operating a Diesel motor on fuel contaminated with Petrol. Likely implications of driving on the incorrect fuel normally include the motor not starting, running unevenly, loss in power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are several of the most common Petrol in Diesel signs and symptoms, and if you notice any of them cease driving and get it removed asap.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
