Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a very common error. And exactly what you need to do about it will depend on a variety of factors. If you would like to find out what you have to do to fix it then keep on reading.
Right here are the key variables to take into consideration whenever deciding on whether to get a fuel drain:

  1. How much Diesel have you put into the Mercedes, taking into consideration that the fuel tank capacity of the Mercedes S400 Hybrid is probably roughly 90 litres?
    1. Hardly any Diesel, something like 4.5 litres of Diesel in a Petrol S400 Hybrid will more often than not not be a significant problem. Experience has taught us that quantities under 4.5 litres (5% of the total fuel tank capacity) is quite often able to be sufficiently diluted simply by completely filling the rest of the tank with Petrol.
      It is relatively unusual to encounter a vehicle experiencing problems with less than 5% incorrect fuel contamination. Keep in mind that it is very rare - in no way impossible to find. There are a few automobiles that won't endure any degree of contamination whatsoever.
    2. In between 4.5 and 9 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our experience has shown us that as many people get away with this as all those who don't. Any time you are trying to decide whether or not to risk it and simply fill it up consider that it is much like wagering everything on black - you've got a 50/50 possibility of it working.
    3. Anything more than 9 litres of Diesel in your Petrol S400 Hybrid should straight away be drained out seeing as your likelihood of succeeding with this amount of contamination is very likely below one in fifty - extremely big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance troubles after putting the wrong fuel in the S400 Hybrid? If so, get it drained regardless of the amount of Diesel or the contamination ratio. Still running a vehicle that is already starting to suffer from the effects of fuel contamination will probably likely cause more and more harm affecting your fuel system parts.
  3. Do you want peace of mind?
    Simply get it drained. Whatever the contamination ratio, there is inevitably a certain level of danger resulting from driving a Petrol engine on Petrol contaminated with Diesel. Possible outcomes of driving a car on the wrong fuel can include the motor not starting, running lumpy, loss in power, degradation of the high-pressure pump, damaged or clogged injectors, etc. These are several of the commonest Diesel in Petrol symptoms, and in the event that you observe any of them stop and have it drained right away.

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?

Answer

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

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
