jerryjetman Posted May 8, 2008 Share Posted May 8, 2008 Has anyone out there heard of z-max ? It's an oil/fuel/trans/power steering additive.I work with a guy that says he increased his gas mileage from 36 to 42 mpg on a Honda Civic.I find that hard to believe. With gas here @ $3.69 a gallon,I'll try any thing at this point. Link to comment Share on other sites More sharing options...

Also, with additives, you gotta consider cost effectiveness, as in how much of the stuff do you have to buy and what kind of gains you get. Prolly just bs cuz all it does is clean your system. so if your mileage increases its cuz you got a lot of crud built up in there. Link to comment Share on other sites More sharing options...
