Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regularly occurring error. And exactly what you should do about it varies according to a few things. If perhaps you would like to find out what you ought to do to sort it out then stay with me.
Listed below are the most important variables to to consider when choosing whether to have the car drained:

  1. Exactly how much Diesel did you put in to the Mercedes, considering that the fuel tank capacity of your Mercedes A45 AMG is usually about 50 litres?
    1. A modest quantity of Diesel, less than 2.5 litres of Diesel in a Petrol A45 AMG will usually not be a big problem. Experience has proven to us that anything less than 2.5 litres (5% of the whole fuel tank volume) is usually able to be adequately diluted simply by completely topping up the remainder of the tank with Petrol.
      It's extremely unusual to come across a car or truck going through problems due to under 5% wrong fuel contamination. Keep in mind it's rare - in no way impossible to encounter. You can get certain cars that don't endure any level of contamination in the slightest.
    2. Between 2.5 and 5 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 situation. Our expertise demonstrates that as many people get away with it as those who don't. Whenever deciding on whether to chance it and basically fill it up consider that it is the same thing as wagering everything on black - you've got a 50/50 possibility of it working out.
    3. Anything over 5 litres of Diesel in a Petrol A45 AMG really should immediately be drained out as your probability of succeeding with this amount of contamination is more than likely lower than one in fifty - definitely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you seen any performance issues after putting the bad fuel in your A45 AMG? If that's the case, get it emptied irrespective of the quantity of Diesel or even the contamination percentage. Still driving a car that is already beginning to suffer the effects of wrong fuel contamination can only cause increasing amounts of harm affecting the fuel system.
  3. Would you like reassurance?
    You should get it drained. Whatever the contamination percentage, there is invariably some amount of threat connected to running a Petrol engine on fuel contaminated with Diesel. Possible consequences of driving a car on the incorrect fuel normally include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, damaged or bunged injectors, and so on. These are several of the most common Diesel in Petrol warning signs, and should you notice any of them then stop and have it removed asap.

Diesel in Petrol FAQs

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.
