does anyone use bmw fuel system cleaner and is there any need for that?
I drive 2012 335is and use Shell Vpower. Car is amazing and purrs like a cat. Any comments would greatly appreciated.

using that or something like the bottled techron fuel cleaner makes sense after more mileage. i would use a bottle and empty tank before each oil change, as it kills the oil.

+1 about Techron, but I do not think it applies to the 335 (direct injection) engines. Do a search.
