Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a regular error. And exactly what you need to do about it is dependent upon a few factors. If you want to find out what to do about this then continue reading.
Right here are the key factors to consider whenever deciding on whether to have a fuel drain:

  1. What level of Diesel did you put in to the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes C180 is probably around 62 litres?
    1. Hardly any Diesel, as little as 3.1 litres of Diesel in a Petrol C180 will generally not be a major problem. Experience has shown us that quantities less than 3.1 litres (roughly 5% of the whole fuel tank capacity) is usually capable of being adequately diluted simply by thoroughly filling the tank with Petrol.
      It is extremely unusual to encounter a vehicle having issues due to less than 5% wrong fuel contamination. Please remember it is very infrequent - definitely not impossible to find. You can get a number of motor vehicles that won't stand any degree of fuel contamination in the slightest.
    2. In between 3.1 and 6.2 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 situation. Our expertise has demonstrated that as many drivers get away with this as those people who break down. Whenever you are trying to decide whether or not to chance it and just top it up recognise that it is very much like gambling all of it on black - you've got a 50/50 possibility of it working out.
    3. Anything over 6.2 litres of Diesel in your Petrol C180 should really as soon as possible be removed since your likelihood of getting away with this amount of contamination is almost certainly less than one in fifty - definitely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you detected any performance troubles after putting the incorrect fuel in the C180? If so, have it drained regardless of the volume of Diesel or the contamination ratio. Still running a motor vehicle that is beginning to suffer the consequences of wrong fuel contamination will likely result in progressively more damage being done to the fuel system parts.
  3. Do you need security?
    In that case get it drained. Whatever the contamination ratio, there is always a certain level of risk affiliated with driving a Petrol motor on fuel contaminated with Diesel. Probable final outcomes of driving on the wrong fuel normally include the motor not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are some of the commonest Diesel in Petrol symptoms, and should you notice any of them then stop and get it drained as soon as possible.

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.
