Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a well-known error. And exactly what you want to do about it varies according to several different things. Assuming you would like to find out what you should do to fix it then keep on reading.
Listed here are the most crucial factors to consider when figuring out whether to get a fuel drain:

  1. How much Diesel have you put in to the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes SL 63 AMG is usually about 80 litres?
    1. A tiny amount of Diesel, as little as 4 litres of Diesel in a Petrol SL 63 AMG will in most situations not really be a massive problem. Experience has demonstrated to us that anything under 4 litres (almost 5% of the total fuel tank) is often capable of being completely diluted simply by entirely filling the tank with the appropriate fuel.
      It is rather uncommon to come across a motor vehicle experiencing issues due to under 5% wrong fuel contamination. Keep in mind that it is very rare - definitely not impossible to find. There are actually certain vehicles that don't endure any amount of fuel contamination at all.
    2. Between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 scenario. Our experience demonstrates that as many people get away with it as all those who break down. When trying to decide whether or not to risk it and just simply top it up bear in mind that it is much like gambling everything on black - you will have a 50/50 possibility of it working out.
    3. Anything more than 8 litres of Diesel in your Petrol SL 63 AMG must right away be drained out seeing that your likelihood of driving with this quantity of contamination is more than likely less than one in 50 - seriously huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any kind of performance difficulties as a result of putting the bad fuel in the SL 63 AMG? If you have, get it emptied no matter the amount of Diesel or the contamination percentage. Continually driving a motor vehicle that is already starting to suffer the effect of wrong fuel contamination will definitely cause more damage being caused to your fuel system parts.
  3. Do you want security?
    In that case get it drained. Regardless of contamination percentage, there is always some degree of risk caused by driving a Petrol vehicle on Petrol contaminated with the wrong fuel. Probable consequences of driving on the wrong fuel include things like the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the most common Diesel in Petrol signs or symptoms, and in the event that you notice any of them then stop and have it drained as soon as possible.

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

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.
