Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a well-known mistake. And exactly what you want to do about it hinges on several factors. In case you want to know what you have to do about this then stay with me.
Right here are the most important factors to consider when deciding whether or not to get a fuel drain:

  1. Exactly how much Diesel have you put in the Mercedes, considering that the fuel tank capacity of the Mercedes CLK 200 is normally about 62 litres?
    1. A small amount of Diesel, as little as 3.1 litres of Diesel in a Petrol CLK 200 will in most situations not necessarily be a big problem. Experience has demonstrated to us that quantities under 3.1 litres (which is close to 5% of the entire fuel tank capacity) is often able to be completely diluted by entirely topping the tank with the right fuel.
      It's highly rare to find a vehicle having difficulties with under 5% wrong fuel contamination. Do not forget that it's unusual - in no way impossible to find. There are some automobiles that don't endure any degree of contamination at all.
    2. Somewhere between 3.1 and 6.2 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 scenario. Our working experience has shown us that as many drivers get away with this as those who don't. Whenever you are trying to decide whether or not to risk it and just top it up recognise that it is much like gambling all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 6.2 litres of Diesel in a Petrol CLK 200 must straightaway be removed seeing that your probability of driving with this quantity of contamination is probably lower than one in fifty - definitely huge odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noted any performance problems as a result of putting the wrong fuel in your CLK 200? If you have, get it drained irrespective of the amount of Diesel or the contamination ratio. Continuing to run driving a vehicle that is already beginning to suffer from the effects of fuel contamination will probably typically result in even more damage affecting your fuel system.
  3. Do you want assurance?
    In that case get it drained. No matter the contamination percentage, there is always some amount of danger connected with operating a Petrol motor on Petrol contaminated with the wrong fuel. Probable implications of driving a vehicle on the wrong fuel include the engine refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, worn or bunged injectors, and the like. These are a few of the commonest Diesel in Petrol signs or symptoms, and should you recognise any of them stop and get it drained right away.

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?


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?


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?


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?


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?


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?


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.
