Mercedes Fuel Drain

ABOUT

Putting Diesel in a Petrol Mercedes is a regularly occurring problem. And its remedy is based on several things. Assuming you want to know what you need to do about it then keep on reading.
Here are the key factors to keep in mind whenever determining whether or not to have a fuel drain:

  1. Exactly how much Diesel did you put into the Mercedes, taking into account that the fuel tank capacity of your Mercedes B220 is in most cases roughly 50 litres?
    1. A modest amount of Diesel, less than 2.5 litres of Diesel in a Petrol B220 will in most cases not be a massive problem. Experience has proven to us that anything under 2.5 litres (approximately 5% of the total fuel tank volume) is generally able to be completely diluted by means of thoroughly filling up the rest of the tank with Petrol.
      It's highly unusual to encounter an automobile having difficulties due to below 5% wrong fuel contamination. Do not forget that it is infrequent - definitely not impossible to find. You can get certain motor vehicles that will not stand any amount of contamination in the slightest.
    2. In between 2.5 and 5 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 condition. Our expertise has proven that as many motorists get away with this as those who don't. When you are deciding on whether or not to chance it and just top it up bear in mind that it is the same as betting your car on black - you will have a 50/50 chance of it working out.
    3. Anything above 5 litres of Diesel in a Petrol B220 really should right away be drained as your likelihood of succeeding with this level of contamination is more than likely lower than one in fifty - really big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any kind of performance troubles since putting the bad fuel in the B220? If you have, get it removed regardless of the quantity of Diesel or even the contamination ratio. Continually running a motor vehicle that is beginning to suffer the consequences of fuel contamination can only end up in more and more damage affecting your fuel system components.
  3. Would you like security?
    You should get it drained. Regardless of the contamination ratio, there is invariably some degree of threat associated with driving a Petrol engine on fuel contaminated with Diesel. Probable implications of driving on the wrong fuel can include the motor refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are some of the most common Diesel in Petrol symptoms, and should you recognise any of them then stop and have it drained right now.

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.
