does Z max really work?

sn95stang42 · 04-25-2008

What kind of gas millage are you guys getting? The reason I as is because about a month ago i try ed out the Zmax stuff and the past 4 tanks of gas i have been getting close to 20 mpg give or take a few. I really didn't pay much attention before i used the zmax so i just wanted to no if it really worked or not?

if your getting 20mpg in the city...that is awesome...i always wondered if that was worth the money...guess carol shelby was not lying...i'll have to try next oil change!

i would say its working then just a heads up guys it comes with a gas treatment and a engine treatment you are suppose to put the gas treatment in ant a 1/4 tank and run it to almost empty and you don't have to change your oil to put it in.

i call horsesh!t. if it made THAT much of a difference it would be all over the national news, science shows & publications, and the big oil companies would ALL have their checkbooks out to keep it off the market.
