I saw the infomercial, claiming better gas mileage and more enginde longevity, but I wonder if the additive doesn't gain the better gas mileage through reducing the viscosity of the oil, and hence reducing friction at the expense of engine protection? VMax claims BOTH, but I find this hard to believe. What do you think? Has anyone seen an objective test, or better yet, have any of you TESTED this stuff? Thanks.
