Mercedes Fuel Drain


Filling up with Petrol in a Diesel Mercedes is a regularly occurring mistake to make. And what you should do about it varies according to several different things. If you would like to find out what you ought to do to fix it then please read on.
Here are the main factors to be aware of when figuring out whether or not to get a fuel drain:

  1. What level of Petrol have you put in to the Mercedes, considering that the fuel capacity of the Mercedes A200 CDI is usually roughly 54 litres?
    1. Hardly any Petrol, less than 2.7 litres of Petrol in a Diesel A200 CDI will generally not necessarily be a big problem. Experience has taught us that an amount under 2.7 litres (roughly 5% of the overall fuel tank capacity) is usually capable of being adequately diluted by totally filling up the tank with Diesel.
      It's quite rare to come across a vehicle experiencing issues because of less than 5% wrong fuel contamination. Please remember it is very infrequently found - in no way impossible to find. You can get certain automobiles that will not endure any quantity of fuel contamination at all.
    2. Somewhere between 2.7 and 5.4 litres of Petrol in the Mercedes (5 to 10%) is a 50/50 scenario. Our practical experience demonstrates that as many drivers get away with it as those who don't. Any time you're deciding whether to chance it and basically top it up remember that it is the same as gambling everything on black - you have got a 50/50 chance of it working.
    3. Anything above 5.4 litres of Petrol in your Diesel A200 CDI should immediately be drained since your probability of driving with that amount of contamination is certainly lower than one in fifty - extremely long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you noted any performance troubles after putting the wrong fuel in your A200 CDI? In that case, have it removed no matter the volume of Petrol or even the contamination ratio. Continually driving a vehicle that is already starting to suffer from the effect of fuel contamination will typically end up in even more harm being caused to the fuel system parts.
  3. Are you interested in peace of mind?
    In that case get it removed. No matter the contamination ratio, there is invariably some amount of danger affiliated with operating a Diesel engine on Diesel contaminated with the incorrect fuel. Possible consequences of driving on the wrong fuel include the engine not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are several of the commonest Petrol in Diesel warning signs, and in the event that you observe any of them cease driving and get it drained 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?


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.
