wtf... yesterday i went to honda dealership's parts dept.. and looky what i saw... ZMAX. they say they pour that stuff in the car everytime when customers brings their car in for tune ups. i know zmax is good for older motors... but what about pretty new motors? cuz i have a the Zmax kit from pepboys and certain bottles i don't know where i should pour it to. there is a small pink bottles that is supposely for the transmission... but my is 5 speed... so what i pour it into my gear box??? then there are other engine treatment stuff. bottom line... has anyone ever used these on their civics?? if so... how was it?
