Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a regularly occurring mistake to make. And exactly what you should do about it varies according to a few factors. Assuming you want to know what you ought to do about it then keep reading.
Listed here are the most important variables to think about whenever deciding on whether to have it drained:

  1. How much Petrol did you put into the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes E270 CDI is most likely approximately 65 litres?
    1. Hardly any Petrol, something like 3.25 litres of Petrol in a Diesel E270 CDI will typically not necessarily be a major problem. Experience has proven to us that quantities under 3.25 litres (which is close to 5% of the entire fuel tank volume) is oftentimes capable of being adequately diluted through wholly filling up the tank with the right fuel.
      It is relatively rare to encounter a motor vehicle experiencing issues because of lower than 5% wrong fuel contamination. Keep in mind that it's infrequently found - certainly not impossible to encounter. You can get certain automobiles that will not stand any level of contamination whatsoever.
    2. Anywhere between 3.25 and 6.5 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 situation. Our experience has confirmed that as many drivers get away with it as all those who break down. When you are deciding on whether to risk it and basically top it up recognise that it is much like wagering it all on black - you will have a 50/50 chance of it working.
    3. Anything in excess of 6.5 litres of Petrol in your Diesel E270 CDI ought to promptly be drained because your probability of getting away with this level of contamination is more than likely lower than one in 50 - extremely huge odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you noticed any performance concerns as a result of putting the bad fuel in your E270 CDI? In that case, get it drained no matter the volume of Petrol or even the contamination percentage. Still running a motor vehicle that is currently beginning to suffer the effect of wrong fuel contamination will only bring about progressively more damage affecting your fuel system.
  3. Are you interested in assurance?
    Then simply just get it removed. Regardless of contamination ratio, there is always some extent of danger in connection with operating a Diesel engine on Diesel contaminated with the incorrect fuel. Probable final outcomes of driving a car on the wrong fuel include the motor not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn or bunged injectors, and the like. These are several of the most common Petrol in Diesel signs or symptoms, and in the event that you observe any of them then cease driving and get it drained as soon as possible.

Petrol in Diesel FAQs

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.
