Mercedes Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Mercedes is a usual problem. And what you should do about it will depend on a variety of things. In case you want to find out what you must do to fix it then read on.
Right here are the most crucial variables to keep in mind when making a decision whether to get the car drained:

  1. What amount of Diesel have you put in to the Mercedes, taking into consideration that the fuel capacity of the Mercedes SL 350 is in most cases around 80 litres?
    1. A modest quantity of Diesel, less than 4 litres of Diesel in a Petrol SL 350 will generally not necessarily be a significant problem. Experience has proven to us that anything under 4 litres (which is 5% of the total fuel tank volume) is frequently able to be adequately diluted by entirely filling up the remainder of the tank with the correct fuel.
      It is quite unusual to come across a vehicle suffering from issues with below 5% incorrect fuel contamination. Remember that it is very uncommon - in no way impossible to encounter. There are some automobiles that will not stand any degree of contamination whatsoever.
    2. Somewhere between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our practical experience has revealed that as many motorists get away with this as those who break down. Any time you're deciding on whether or not to chance it and just fill it up remember that it is exactly like betting your car on black - you will have a 50/50 chance of it being ok.
    3. Anything over 8 litres of Diesel in your Petrol SL 350 must straightaway be drained out because your likelihood of succeeding with this quantity of contamination is in all likelihood less than one in fifty - genuinely long 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 SL 350? If so, have it emptied no matter the volume of Diesel or even the contamination percentage. Still running a motor vehicle that is starting to suffer the effects of wrong fuel contamination can likely lead to increasing amounts of damage being caused to your fuel system parts.
  3. Do you need security?
    Simply get it drained. Regardless of contamination ratio, there is inevitably some extent of danger caused by operating a Petrol engine on Petrol contaminated with Diesel. Likely implications of driving a vehicle on the wrong fuel normally include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or blocked injectors, and so forth. These are some of the most common Diesel in Petrol warning signs, and in the event that you detect any of them stop and have it drained right away.

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.
