Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a very common mistake. And its solution is based on various things. In the event that you want to find out what you have to do about it then stay with me.
Right here are the most crucial variables to keep in mind when deciding whether or not to have a fuel drain:

  1. What level of Diesel did you put in to the Mercedes, taking into consideration that the fuel capacity of your Mercedes CLK 430 is in most cases approximately 62 litres?
    1. A modest quantity of Diesel, something like 3.1 litres of Diesel in a Petrol CLK 430 will in most situations not really be a big problem. Experience has demonstrated to us that anything under 3.1 litres (5% of the overall fuel tank volume) is often able to be completely diluted through entirely filling the tank with Petrol.
      It is extremely rare to come across a vehicle suffering from problems because of lower than 5% wrong fuel contamination. Please remember it's rare - in no way impossible to encounter. You will discover certain cars that won't endure any degree of fuel contamination whatsoever.
    2. In between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is really a 50/50 condition. Our working experience demonstrates that as many people get away with it as all those who don't. Whenever you are deciding on whether or not to chance it and just simply fill it up remember that it is the same as gambling everything on black - you've got a 50/50 chance of it working.
    3. Anything more than 6.2 litres of Diesel in a Petrol CLK 430 really should straightaway be drained out since your probability of driving with this quantity of contamination is in all likelihood lower than one in fifty - extremely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you seen any kind of performance difficulties since putting the incorrect fuel in the CLK 430? If that's the case, have it removed regardless of the quantity of Diesel or even the contamination percentage. Continuing to run driving a vehicle that is currently starting to suffer the effects of fuel contamination will probably typically cause increasing amounts of harm being caused to the fuel system.
  3. Do you need reassurance?
    Then simply just get it removed. Regardless of contamination ratio, there is invariably some extent of risk caused by running a Petrol engine on Petrol contaminated with Diesel. Probable final outcomes of driving a car on the wrong fuel normally include the engine not starting, running lumpy, lack of power, degradation of the high-pressure pump, worn or blocked injectors, and so forth. These are a few of the most frequently seen Diesel in Petrol warning signs, and if you observe any of them then stop driving and have it removed asap.

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?


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.
