Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a well-known problem. And exactly what you should do about it hinges on various things. Assuming you want to find out what you ought to do to sort it out then stay with me.
Listed here are the key variables to take into consideration when deciding whether or not to have the car drained:

  1. What amount of Diesel did you put in to the Mercedes, keeping in mind that the fuel tank capacity of your Mercedes A190 is most likely approximately 54 litres?
    1. Hardly any Diesel, as little as 2.7 litres of Diesel in a Petrol A190 will generally not be a massive problem. Experience has demonstrated to us that anything less than 2.7 litres (5% of the whole fuel tank) is oftentimes capable of being sufficiently diluted by means of totally topping up the tank with Petrol.
      It's pretty rare to find a car or truck going through problems with lower than 5% incorrect fuel contamination. Keep in mind it's infrequent - not impossible to find. You can get a few automobiles that will not stand any amount of fuel contamination at all.
    2. In between 2.7 and 5.4 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 scenario. Our practical experience demonstrates that as many motorists get away with it as those people who don't. When deciding upon whether or not to chance it and just top it up bear in mind that it is the same as gambling your car on black - you have got a 50/50 chance of it working out.
    3. Anything over 5.4 litres of Diesel in your Petrol A190 should right away be removed seeing as your probability of getting away with that amount of contamination is undoubtedly less than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance difficulties since putting the incorrect fuel in the A190? If you have, have it emptied no matter the quantity of Diesel or even the contamination ratio. Continually running a vehicle that is already starting to suffer from the effect of fuel contamination can only end up in more and more damage being done to your fuel system components.
  3. Do you want reassurance?
    In that case get it removed. No matter the contamination ratio, there is invariably a certain level of danger caused by driving a Petrol motor on Petrol contaminated with Diesel. Possible final outcomes of driving on the wrong fuel include things like the engine refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, worn or bunged injectors, etc. These are some of the most common Diesel in Petrol warning signs, and if you notice any of them then stop and get it drained right away.

Diesel in Petrol Questions

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

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