I got this answer from one of the users: “Get some fuel injector cleaner and add 1 full bottle to a half tank of gas. Run it til the fuel warning appears on the MFD, then continue driving.”


So...



Get some fuel injector cleaner


I looked for that, there are many types and brands. There is something like Fuel cleaner, and fuel INJECTOR system or something like that. which one? and do I have to get the german one? or the American STP would be fine?


add i full bottle to a half tank of gas.



The dealer told me I that the car should be full before putting the cleaner.
...but most of the people there are stupid, so... I should do it the same way you said it? half tank?


Run it til the fuel warning appears on the MFD, then continue driving.



heh, I'm thick maybe :p
But you meant I should drive my car around till the warning appears and continue to drive? till when? and when should I refuel?

One last question if no one minds...
is it okay to switch between gas types every once in a while?
I want to use that fuel cleaner now, and use the ultra super gas and then after a while (couple of days or weeks) go back to the regular gas I used to use.
so?

i would be careful with that, maybe ask the dealer about whether it is appropriate. That said, I only use Lubro-Moly:

One question- why do you think you need FI cleaner?

MB does not sanction the use of fuel/oil additives.
