Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a well-known problem. And its remedy depends on several different things. In case you want to find out what to do to sort it out then please read on.
These are the key factors to be aware of when determining whether to have a fuel drain:

  1. What amount of Diesel have you put into the Mercedes, taking into consideration that the fuel tank capacity of your Mercedes CLS 280 is usually around 80 litres?
    1. A modest quantity of Diesel, less than 4 litres of Diesel in a Petrol CLS 280 will in most cases not be a massive problem. Experience has shown us that quantities under 4 litres (which is roughly 5% of the total fuel tank capacity) is oftentimes able to be adequately diluted by completely topping up the rest of the tank with Petrol.
      It is quite uncommon to come across a car having difficulties with less than 5% wrong fuel contamination. Keep in mind that it is very infrequent - not impossible to find. There are a few automobiles that will not stand any degree of fuel contamination at all.
    2. Anywhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 situation. Our experience has shown that as many people get away with this as those people who don't. When figuring out whether to risk it and basically top it up bear in mind that it is exactly like betting everything on black - you've got a 50/50 chance of it being ok.
    3. Anything over 8 litres of Diesel in your Petrol CLS 280 ought to straightaway be drained because your probability of succeeding with this level of contamination is almost certainly lower than one in fifty - truly huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance issues since putting the incorrect fuel in the CLS 280? In that case, get it emptied regardless of the amount of Diesel or even the contamination percentage. Still running an automobile that is beginning to suffer from the consequences of wrong fuel contamination will probably typically end up in more harm affecting the fuel system.
  3. Are you interested in security?
    Then simply just get it removed. Regardless of contamination ratio, there is invariably some degree of risk resulting from running a Petrol engine on Petrol contaminated with the incorrect fuel. Probable implications of driving on the incorrect fuel normally include the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn out or blocked injectors, and so forth. These are a few of the most typical Diesel in Petrol signs or symptoms, and should you recognise any of them stop and get it removed as soon as possible.

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.
