Mercedes Fuel Drain

ABOUT

Putting Diesel in a Petrol Mercedes is a fairly typical error. And its remedy depends upon an assortment of things. If perhaps you would like to know what you should do about it then keep on reading.
Here are the most crucial factors to to consider whenever choosing whether to have the car drained:

  1. What amount of Diesel did you put into the Mercedes, bearing in mind that the fuel tank capacity of your Mercedes SLK 200 is in most cases about 53 litres?
    1. Hardly any Diesel, as little as 2.65 litres of Diesel in a Petrol SLK 200 will normally not really be a massive problem. Experience has taught us that an amount under 2.65 litres (close to 5% of the overall fuel tank capacity) is generally able to be completely diluted simply by totally filling up the tank with Petrol.
      It is very unusual to come across a vehicle experiencing issues because of under 5% wrong fuel contamination. Please remember it is infrequently found - certainly not impossible to encounter. You will discover some automobiles that don't stand any level of fuel contamination in the slightest.
    2. Between 2.65 and 5.3 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 situation. Our practical experience has revealed that as many motorists get away with it as those who break down. Whenever you are trying to decide whether to chance it and simply top it up bear in mind that it is very much like gambling your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything above 5.3 litres of Diesel in a Petrol SLK 200 ought to straight away be drained because your likelihood of getting away with this quantity of contamination is more than likely below one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance issues after putting the wrong fuel in the SLK 200? In that case, have it drained regardless of the quantity of Diesel or the contamination ratio. Continuing to run driving a vehicle that is beginning to suffer from the consequences of fuel contamination will probably just result in more harm being done to the fuel system.
  3. Do you want assurance?
    You should get it emptied. Regardless of the contamination ratio, there is always some extent of risk resulting from running a Petrol motor on Petrol contaminated with Diesel. Probable implications of driving on the incorrect fuel normally include the motor refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn or bunged injectors, and so forth. These are several of the most common Diesel in Petrol symptoms, and if you recognise 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.
