摘要: A fuel additive composition comprising a sustained release component and an additive component, the additive component is effective to provide at least one benefit to a fuel when released into the fuel, the sustained release component is (1) a polymeric material, (2) substantially insoluble in the fuel, and (3) effective to reduce the rate of release of the additive component into the fuel relative to an identical composition without the sustained release component.
