Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a usual mistake to make. And its remedy is based on an assortment of things. In the event that you want to find out what you must do to fix it then stay with me.
Listed below are the key factors to take into consideration when figuring out whether to get it drained:

  1. What level of Petrol did you put in the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes A220 CDI is normally roughly 50 litres?
    1. A small amount of Petrol, less than 2.5 litres of Petrol in a Diesel A220 CDI will in most cases not necessarily be a significant problem. Experience has taught us that quantities under 2.5 litres (close to 5% of the total fuel tank volume) is generally capable of being sufficiently diluted by means of thoroughly filling the remainder of the tank with the appropriate fuel.
      It's relatively uncommon to come across a motor vehicle suffering from difficulties due to lower than 5% incorrect fuel contamination. Do not forget that it is rare - definitely not impossible to find. There are actually a number of automobiles that won't stand any amount of contamination at all.
    2. Somewhere between 2.5 and 5 litres of Petrol in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our experience has shown us that as many drivers get away with it as those people who don't. Any time you are deciding upon whether or not to chance it and just simply top it up remember that it is just like betting everything on black - you have got a 50/50 possibility of it working out.
    3. Anything more than 5 litres of Petrol in a Diesel A220 CDI really should promptly be drained out because your probability of getting away with this level of contamination is in all likelihood less than one in fifty - truly long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you detected any kind of performance troubles as a result of putting the incorrect fuel in the A220 CDI? In that case, have it drained regardless of the amount of Petrol or the contamination percentage. Continually driving an automobile that is currently starting to suffer the consequences of wrong fuel contamination will probably definitely result in progressively more damage affecting the fuel system parts.
  3. Are you looking for reassurance?
    In that case get it removed. No matter the contamination ratio, there is always a certain level of threat affiliated with driving a Diesel vehicle on fuel contaminated with the wrong fuel. Probable results of driving a vehicle on the incorrect fuel include the engine refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the most common Petrol in Diesel signs or symptoms, and should you observe any of them stop driving and have it drained immediately.

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.
