Techron is the only one with using.

I've had very good, very noticeable results with synthetic Valvoline
cleaner.  $9 from Wal-Mart.  Techron's probably great too, but I have
not used it in a Nissan.  When the deposits build up, after say
30-40,000 miles, there can be a big hit on low-end acceleration.  On
my '96 I30t at least.  I didn't even realize it until I rented a 4
cyl. Altima, and knew immediately it was outgunning my V6 up to 20
mph.

Nissan's official position is that fuel system cleaners should not be
used and can damage injectors.  Don't do it more often than you really
have to.
