Mercedes Fuel Drain


Filling up with Petrol in a Diesel Mercedes is a regularly occurring problem. And what you need to do about it hinges on various factors. In case you want to know what you must do about this then keep on reading.
Listed here the most important variables to be aware of whenever deciding on whether to get the car drained:

  1. What amount of Petrol have you put in the Mercedes, taking into account that the fuel tank capacity of the Mercedes E280 CDI is usually approximately 65 litres?
    1. Hardly any Petrol, less than 3.25 litres of Petrol in a Diesel E280 CDI will normally not necessarily be a major problem. Experience has taught us that anything less than 3.25 litres (which is roughly 5% of the overall fuel tank capacity) is generally able to be adequately diluted by means of wholly topping up the tank with the right fuel.
      It is quite uncommon to come across a motor vehicle going through problems due to lower than 5% wrong fuel contamination. Remember that it is unusual - in no way impossible to encounter. There are a number of automobiles that won't stand any degree of contamination at all.
    2. Anywhere between 3.25 and 6.5 litres of Petrol in the Mercedes (5 to 10%) is more of a 50/50 situation. Our expertise has shown that as many motorists get away with it as those people who don't. When you are deciding upon whether to chance it and basically fill it up consider that it is just like wagering your car on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 6.5 litres of Petrol in a Diesel E280 CDI should really immediately be drained out seeing that your probability of succeeding with this amount of contamination is undoubtedly lower than one in 50 - really big odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you detected any kind of performance difficulties as a result of putting the bad fuel in the E280 CDI? If you have, get it emptied no matter the quantity of Petrol or even the contamination percentage. Proceeding to drive running an automobile that is now starting to suffer from the effects of wrong fuel contamination can just cause increasing amounts of harm affecting the fuel system components.
  3. Would you like peace of mind?
    Then simply just get it drained. Whatever the contamination percentage, there is always some degree of threat resulting from driving a Diesel vehicle on Diesel contaminated with the incorrect fuel. Probable outcomes of driving on the wrong fuel can include the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are a few of the most typical Petrol in Diesel signs or symptoms, and if you detect any of them stop driving and get it removed immediately.

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.
