Anyone try it? I'm on my first tank right now, after running half tank w/a can of this stuff. Bought it for $26 at a Honda Dealership down here. Read some mixed reviews but overall they seemed pretty legit. I got 210,xxx miles on my 22re. Recently changed new plugs/wires/cap & rotor/air filter.... Before the 'treatment' I was averaging about 200-210mi per tank. 23-24mpg Rightnow i just broke 100 miles. I'm a shade above 2/3 tank......Can't really believe it....yet. I'll post back when i'm down to empty. Still driving the same, shifting around 3k rpm. Downshifting at 1800. Can't really drive aggressive anyway with this motor. So far i don't regret spending that $26
Those kinda products work really well once. Removing carbon, cleaning things and getting the mpgs back up to what they should be. I pour water down my carb (engine running 2K and a trickle, Bout 2L worth.), and that will do basically the same thing. Only free.
Ended up pulling 250 miles out of the tank. Looked like it'd hold strong but after half tank it went pretty quickly.
250mi / 8.5gal tank = 29.4mpg On another tank right now. Looks like it's gonna be about the same, maybe a little bit better.
