Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a fairly typical error. And its remedy varies according to a few things. If perhaps you would like to know what it is best to do to sort it out then continue reading.
Listed here are the most crucial factors to keep in mind whenever making a decision whether to get your car drained:

  1. How much Petrol have you put in the Mercedes, considering that the fuel tank capacity of your Mercedes ML 350 CDI is usually around 95 litres?
    1. A tiny quantity of Petrol, something like 4.75 litres of Petrol in a Diesel ML 350 CDI will usually not necessarily be a massive problem. Experience has shown us that quantities less than 4.75 litres (which is almost 5% of the entire fuel tank) is often capable of being sufficiently diluted through completely filling up the remainder of the tank with the correct fuel.
      It is extremely uncommon to come across a car suffering from issues because of less than 5% wrong fuel contamination. Be aware that it's infrequently found - not impossible to find. You can get some automobiles that won't endure any degree of fuel contamination in the slightest.
    2. In between 4.75 and 9.5 litres of Petrol in the Mercedes (from 5 to 10%) is more of a 50/50 scenario. Our working experience has proven that as many motorists get away with it as all those who break down. Any time you are deciding upon whether or not to risk it and simply top it up recognise that it is the same as gambling your car on black - you have got a 50/50 chance of it working.
    3. Anything above 9.5 litres of Petrol in your Diesel ML 350 CDI must right away be removed seeing as your probability of succeeding with that quantity of contamination is almost certainly below one in fifty - truly huge odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you seen any performance concerns ever since putting the wrong fuel in your ML 350 CDI? If that's the case, have it drained regardless of the quantity of Petrol or even the contamination percentage. Still driving a vehicle that is currently beginning to suffer from the effects of fuel contamination will probably only cause progressively more harm being done to the fuel system parts.
  3. Would you like assurance?
    Simply get it drained. Whatever the contamination percentage, there is invariably some extent of threat linked with running a Diesel engine on fuel contaminated with Petrol. Possible final outcomes of driving a car on the incorrect fuel include the motor refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are several of the most frequently seen Petrol in Diesel signs and symptoms, and should you notice any of them then stop and get it drained right now.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
