Product Description
Gas prices keep going up and you're spending more money on your car than ever before. You're probably just hoping that gas prices will eventually go down but who can really count on the big oil companies? Take matters into your own hands with zMAX™ and increase your gas mileage as well as save your money! zMAX™ is not an oil additive but a micro-lubricant that actually soaks into metal. The small micro-lubricants get into places that regular oils can't reach! They clean out carbon varnish and other deposits that can make your engine run at a high temperature. With zMAX™ you'll get better gas mileage, reduced emissions and more power. Because zMAX™ is not an oil additive, it treats the metal not the oil. zMAX™ disperses carbon and tunes your combustion chamber.

i used this on an old 85 dodge van trying to get the mileage up from 10 mpg - maybe it went to 11 mpg or just ordinary fluctuation - but not worth the money - it may have cleaned the engine , can't tell - no significant changes .
It works!!

I used this product one year ago on my 97 accord and it works. i noticed immediately the engine ran smoother and more quieter. Gas mileage went up about 3 miles per gallon. I had told my friends to try it and see what they said. It seemed that it works better on 4 & 6 cylinder vehicles than 8's. I am going to keep using this product for as long as they make it.
