The state board may request, from any person who advertises, or causes to be advertised, in any manner or claim that a fuel or fuel additive reduces motor vehicle exhaust emissions, a report detailing the data which supports the advertiser’s claims of emission reduction by that fuel or fuel additive.

The state board may conduct, and may request the Department of Consumer Affairs to assist the state board in, such further investigation as may appear warranted under the circumstances.

If the state board, or the state board and the Department of Consumer Affairs if the latter has assisted in the investigation, determines that the fuel or fuel additive is not substantially as effective as it is claimed to be in the advertisement for it, the state board shall report the findings to the Attorney General for whatever action under the Business and Professions Code or other law the Attorney General finds appropriate.
