Mercedes Fuel Drain

ABOUT

Putting Diesel in a Petrol Mercedes is a regularly occurring mistake to make. And its remedy is based on various factors. Assuming you would like to know what it is advisable to do to fix it then keep on reading.
Listed here the key factors to consider when figuring out whether or not to have it drained:

  1. What amount of Diesel did you put into the Mercedes, keeping in mind that the fuel tank capacity of your Mercedes SL 280 is most likely about 80 litres?
    1. Hardly any Diesel, less than 4 litres of Diesel in a Petrol SL 280 will usually not really be a significant problem. Experience has proven to us that an amount under 4 litres (about 5% of the entire fuel tank capacity) is generally capable of being completely diluted through entirely topping the rest of the tank with the appropriate fuel.
      It is rather uncommon to find a car or truck going through difficulties with below 5% incorrect fuel contamination. Please remember it is rare - not impossible to encounter. There are actually certain automobiles that will not endure any degree of contamination in the slightest.
    2. Somewhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 condition. Our practical experience has proven that as many people get away with this as those who break down. Any time you are deciding whether or not to chance it and simply top it up remember that it is exactly like wagering everything on black - you will have a 50/50 chance of it being ok.
    3. Anything in excess of 8 litres of Diesel in your Petrol SL 280 should really as soon as possible be drained because your likelihood of getting away with that level of contamination is certainly lower than one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you seen any kind of performance issues since putting the wrong fuel in the SL 280? If so, have it drained no matter the volume of Diesel or even the contamination percentage. Continuing to drive driving a vehicle that is now beginning to suffer the effect of fuel contamination can likely end up in more damage being done to the fuel system parts.
  3. Do you need peace of mind?
    In that case get it drained. No matter the contamination percentage, there is invariably some amount of risk associated with driving a Petrol engine on fuel contaminated with Diesel. Likely final outcomes of driving on the incorrect fuel include the engine not starting, running unevenly, loss in power, wearing of the high-pressure pump, worn or bunged injectors, and so on. These are some of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you detect any of them then stop and have it drained right now.

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?

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

Will driving a Petrol car on Diesel cause damage to it?

Answer

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.
