Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a very common error. And what you want to do about it depends on several different factors. Assuming you would like to know what it is advisable to do to fix it then read on.
Listed here are the most important variables to take into consideration whenever making a decision whether to have a fuel drain:

  1. What amount of Diesel did you put in the Mercedes, bearing in mind that the fuel capacity of your Mercedes E220 is usually approximately 70 litres?
    1. Hardly any Diesel, less than 3.5 litres of Diesel in a Petrol E220 will more often than not not really be a major problem. Experience has demonstrated to us that an amount under 3.5 litres (which is almost 5% of the fuel tank) is sometimes able to be sufficiently diluted simply by thoroughly filling the rest of the tank with the right fuel.
      It's relatively unusual to find a car or truck having difficulties with lower than 5% incorrect fuel contamination. Keep in mind that it is uncommon - certainly not impossible to encounter. There are actually certain cars that will not endure any amount of fuel contamination at all.
    2. In between 3.5 and 7 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 condition. Our experience has demonstrated that as many drivers get away with this as all those who break down. Any time you're trying to decide whether or not to chance it and basically top it up bear in mind that it is very much like gambling your car on black - you will have a 50/50 possibility of it working.
    3. Anything in excess of 7 litres of Diesel in a Petrol E220 really should immediately be removed as your probability of driving with this amount of contamination is certainly below one in 50 - definitely big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noted any performance difficulties since putting the bad fuel in the E220? If you have, have it emptied regardless of the volume of Diesel or even the contamination ratio. Continuing to drive driving an automobile that is now starting to suffer from the effect of wrong fuel contamination can just end up in more damage affecting the fuel system.
  3. Would you like security?
    In that case get it emptied. No matter the contamination percentage, there is inevitably some extent of threat resulting from operating a Petrol motor on fuel contaminated with the incorrect fuel. Probable results of driving on the wrong fuel normally include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are some of the commonest Diesel in Petrol signs and symptoms, and if you recognise any of them cease driving and have it removed asap.

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.
