If this stuff was so good and all of the zMax claims were true, wouldn't all of the automakers use it to increase mileage and power more cheaply than spending millions on R&D in house? Anytime I see a product that makes wild claims about increased mileage, power, and less wear, I think it's all a bunch of BS.

and believing anything the GOV has to say about it is also silly. Do your own testing, if it works- great, if not- leason learned.

GOV doesn't want you to know if how to cheat them out of fuel taxes/costs or not if possible.

there are some pretty mixed reviews that people have on this stuff from actually using it so say no difference and some say amazing but most of the people that say amazing were on cars that have been sitting or had major problems with valves and injectors but i don't think it is worth it just go with lucas that stuff actually works

That was dated february 2001. They are still making those claims so does that mean it actually works?
