Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a well-known error. And what you should do about it depends upon a number of factors. If you would like to find out what to do to fix it then keep reading.
Right here are the most crucial factors to keep in mind whenever deciding on whether to have a fuel drain:

  1. Exactly how much Diesel have you put into the Mercedes, keeping in mind that the fuel capacity of your Mercedes R500 is usually around 80 litres?
    1. A small quantity of Diesel, something like 4 litres of Diesel in a Petrol R500 will normally not necessarily be a huge problem. Experience has proven to us that anything less than 4 litres (which is almost 5% of the overall fuel tank volume) is oftentimes capable of being sufficiently diluted by means of entirely filling the rest of the tank with Petrol.
      It is very uncommon to find a vehicle experiencing problems because of below 5% incorrect fuel contamination. Be aware that it is very unusual - in no way impossible to find. You can get some automobiles that don't endure any degree of contamination whatsoever.
    2. Between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 situation. Our expertise has confirmed that as many people get away with this as all those who don't. Any time you're deciding upon whether to chance it and just fill it up consider that it is the same thing as wagering everything on black - you have a 50/50 possibility of it working out.
    3. Anything in excess of 8 litres of Diesel in your Petrol R500 should really promptly be removed as your probability of driving with that amount of contamination is more than likely below one in 50 - seriously huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noted any kind of performance difficulties ever since putting the wrong fuel in your R500? If that's the case, have it removed irrespective of the quantity of Diesel or the contamination ratio. Still running a car that is currently beginning to suffer from the effects of wrong fuel contamination will typically result in more damage being caused to the fuel system parts.
  3. Do you want reassurance?
    Simply get it drained. Whatever the contamination ratio, there is always some amount of danger affiliated with driving a Petrol motor on fuel contaminated with Diesel. Possible results of driving a car on the wrong fuel can include the engine not starting, running lumpy, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, etc. These are several of the most typical Diesel in Petrol warning signs, and should you recognise any of them then stop driving and get it removed immediately.

Don't simply have any general so-and-so to attend your car. We are Mercedes specialists and possess the qualifications and knowledge required to make certain that you are back on the road with little hassle or worry.

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.
