Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a regular mistake. And its solution varies according to several things. In the event that you want to know what you have to do to sort it out then continue reading.
These are the main factors to think about when deciding on whether to get your car drained:

  1. What amount of Diesel have you put in the Mercedes, taking into consideration that the fuel tank capacity of the Mercedes S280 is most likely about 100 litres?
    1. A tiny quantity of Diesel, something like 5 litres of Diesel in a Petrol S280 will in most cases not necessarily be a significant problem. Experience has demonstrated to us that quantities under 5 litres (about 5% of the total fuel tank) is often able to be sufficiently diluted simply by totally topping the tank with the correct fuel.
      It is rather rare to come across a car going through issues with under 5% incorrect fuel contamination. Do not forget that it is very infrequently found - certainly not impossible to encounter. You can get certain motor vehicles that don't stand any quantity of contamination at all.
    2. Somewhere between 5 and 10 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 situation. Our working experience has confirmed that as many people get away with it as those people who break down. Any time you are figuring out whether or not to risk it and simply fill it up consider that it is the same as gambling it all on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 10 litres of Diesel in a Petrol S280 really should right away be drained since your likelihood of getting away with that amount of contamination is undoubtedly lower than one in 50 - truly big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you observed any performance difficulties ever since putting the incorrect fuel in your S280? If so, get it emptied no matter the volume of Diesel or even the contamination percentage. Continuing to drive driving a vehicle that is currently beginning to suffer the consequences of wrong fuel contamination can typically end up in even more harm being caused to your fuel system.
  3. Are you interested in security?
    Then simply just get it drained. Regardless of the contamination percentage, there is always some extent of danger connected to running a Petrol vehicle on fuel contaminated with Diesel. Possible results of driving a vehicle on the incorrect fuel normally include the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the most common Diesel in Petrol warning signs, and should you recognise any of them then stop driving and get it removed immediately.

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.
