A Survey of American and Canadian Consumer Experience - The Performance of Late Model Year Vehicles Operating on Gasoline With and Without the Gasoline Fuel Additive MMT® 2006-01-3405

This paper presents the results of a three city survey designed to determine the relative frequency of illumination of vehicle on-board diagnostic (OBD) malfunction indicator lights (MIL) on 2001 and later model year vehicles. The survey was conducted in a Canadian market, Regina, and two U.S. markets, Minneapolis and Denver, to assess claims that the presence of methycyclopentadienyl manganese tricarbonyl (MMT®) in gasoline causes the failure of technology necessary to meet stringent Tier 2 emission standards applicable in North America. The results of the survey do not support the claim that MMT® is incompatible with the effective functioning of the advanced vehicle emission technology necessary to meet Tier 2 emission standards. The results substantiate that the performance of the most advanced vehicles operating on gasoline containing MMT® is not materially different from the performance of comparable vehicles operating on gasoline that does not contain MMT®.
