Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a very common mistake to make. And exactly what you need to do about it will depend on an assortment of things. In case you want to know what to do to sort it out then keep on reading.
Let us discuss the key variables to keep in mind whenever choosing whether to have a fuel drain:

  1. How much Diesel have you put in to the Mercedes, taking into consideration that the fuel capacity of the Mercedes S320 L is probably approximately 100 litres?
    1. A small amount of Diesel, as little as 5 litres of Diesel in a Petrol S320 L will typically not be a significant problem. Experience has demonstrated to us that anything less than 5 litres (5% of the total fuel tank capacity) is oftentimes capable of being adequately diluted simply by totally filling up the tank with Petrol.
      It's very rare to come across a vehicle going through problems due to less than 5% wrong fuel contamination. Keep in mind that it is infrequent - definitely not impossible to find. You will discover a few vehicles that won't stand any level of contamination whatsoever.
    2. Between 5 and 10 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our experience has shown us that as many drivers get away with this as those people who break down. When deciding upon whether to chance it and simply top it up recognise that it is the same thing as betting all of it on black - you've got a 50/50 chance of it working.
    3. Anything over 10 litres of Diesel in your Petrol S320 L really should promptly be drained out seeing as your likelihood of succeeding with this level of contamination is probably below one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance concerns since putting the incorrect fuel in the S320 L? In that case, get it removed no matter the volume of Diesel or the contamination percentage. Continuing to run running a car that is now starting to suffer the consequences of fuel contamination can typically lead to progressively more damage being caused to the fuel system parts.
  3. Do you need assurance?
    In that case get it emptied. Regardless of the contamination ratio, there is invariably some extent of risk connected to running a Petrol motor on Petrol contaminated with the incorrect fuel. Likely consequences of driving on the wrong fuel can include the motor refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol symptoms, and should you notice any of them then stop and have it removed 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.
