Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a fairly typical error. And its solution varies according to a number of things. If you want to know what you must do about this then please read on.
Listed here the key factors to be aware of whenever figuring out whether or not to have a fuel drain:

  1. What level of Petrol did you put into the Mercedes, keeping in mind that the fuel capacity of the Mercedes ML 450 CDI is in most cases around 95 litres?
    1. A tiny quantity of Petrol, something like 4.75 litres of Petrol in a Diesel ML 450 CDI will most of the time not necessarily be a significant problem. Experience has proven to us that quantities less than 4.75 litres (about 5% of the fuel tank) is frequently capable of being adequately diluted by entirely filling up the remainder of the tank with the right fuel.
      It's extremely unusual to find a motor vehicle experiencing difficulties due to under 5% wrong fuel contamination. Do not forget that it is very infrequent - not impossible to encounter. You will discover a number of motor vehicles that don't endure any level of contamination at all.
    2. Between 4.75 and 9.5 litres of Petrol in the Mercedes (from 5 to 10%) is really a 50/50 condition. Our expertise demonstrates that as many people get away with it as those who don't. When you are deciding on whether or not to risk it and just fill it up recognise that it is just like wagering your car on black - you have a 50/50 possibility of it working out.
    3. Anything in excess of 9.5 litres of Petrol in a Diesel ML 450 CDI really should promptly be removed seeing that your probability of getting away with this level of contamination is very likely lower than one in 50 - truly huge odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you observed any performance concerns as a result of putting the wrong fuel in the ML 450 CDI? If so, get it drained irrespective of the quantity of Petrol or the contamination percentage. Continuing to run driving an automobile that is starting to suffer from the consequences of fuel contamination can typically result in more harm being done to your fuel system.
  3. Are you looking for assurance?
    Then get it removed. No matter the contamination percentage, there is invariably some amount of danger connected with driving a Diesel motor on Diesel contaminated with the wrong fuel. Possible final outcomes of driving on the wrong fuel include the motor refusing to start, running unevenly, loss in power, wearing of the high-pressure pump, worn out or bunged injectors, etc. These are some of the most typical Petrol in Diesel signs and symptoms, and should you recognise any of them then stop and get it removed as soon as possible.

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?

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