When I was at the dealer for the turn signal switch replacement, I came across with this cleaner. It is made in Canada for Nissan. Product number 99998-80008. I am not sure if they export it to USA or if there is a USA equivalent product.
I would never pour anything to the gas tank because:
-the car is 2011 with 26.000 km, so no need to clean the fuel lines, for now
-I don't trust the off the shelf fuel cleaners
However, this product is "Nissan approved", so I don't think it will do a harm to the injectors.
It says "every two tanks, pour a bottle". I talked to the mechanics at the shop and they said I can use it every 48.000 km and they think "every two tanks" is overkill.
I bought two bottles and put aside. When the car reaches 40 - 50 K, I will use it.
