Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a regularly occurring mistake. And exactly what you need to do about it varies according to several different factors. In the event that you would like to know what you must do about this then stay with me.
Listed below are the most important factors to think about whenever deciding whether to get your car drained:

  1. Exactly how much Diesel did you put into the Mercedes, considering that the fuel tank capacity of your Mercedes CL500 is usually approximately 100 litres?
    1. Hardly any Diesel, less than 5 litres of Diesel in a Petrol CL500 will usually not be a significant problem. Experience has taught us that an amount less than 5 litres (5% of the total fuel tank) is in many instances capable of being adequately diluted through totally filling up the tank with Petrol.
      It's extremely rare to come across an automobile suffering from issues due to lower than 5% wrong fuel contamination. Please remember it is unusual - definitely not impossible to encounter. You can get a number of vehicles that don't endure any amount of contamination whatsoever.
    2. Anywhere between 5 and 10 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 condition. Our expertise has shown that as many drivers get away with this as those who don't. When figuring out whether or not to chance it and just top it up remember that it is just like betting it all on black - you will have a 50/50 possibility of it working out.
    3. Anything above 10 litres of Diesel in a Petrol CL500 should immediately be removed because your probability of succeeding with this quantity of contamination is certainly below one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any kind of performance concerns after putting the incorrect fuel in your CL500? If that's the case, get it emptied irrespective of the quantity of Diesel or the contamination percentage. Still driving a vehicle that is already starting to suffer from the effects of wrong fuel contamination will likely result in progressively more harm being done to the fuel system.
  3. Are you looking for assurance?
    You should get it removed. Regardless of contamination percentage, there is always a certain level of danger connected with running a Petrol vehicle on Petrol contaminated with the incorrect fuel. Probable results of driving on the wrong fuel include things like the motor not starting, running lumpy, losing power, wearing of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most typical Diesel in Petrol signs or symptoms, and if you notice any of them cease driving and get it drained right now.

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.
