Is it worth using z-max in a 02-03?
Does it truly work like they say it does?
What true advantages are there?

 

if youre talking about the same z-max i know of... they are currently under alot of scrutiny and have tons of lawsuits on their hands with hordes of pissed off gullable people..

what exactly are you talking about... that cleaner jazz?i dont know much about it.. but i stumbled across a few articles a while back.. and they werent in the products favor..

 

do a search for seafoam- many here use it for the intake cleaning
seafoam or Redline fuel cleaner in the tank do wonders

Dont add any slippery stuff to the oil- vtec relies on oil pressure changes to operate, dont want to confuse it!

 

ok to run seafoam in the crankcase just before a change to remove sludge from the oil passageways- thats alway good to do
