The Gasoline Protection Program™ (GPP®) defines a level of performance for gasoline additive products that is exclusive to the NMMA. GPP® is a registered trademark. The Center for Quality Assurance (CQA) administers the program on behalf of the NMMA and monitors quality standards through each step in the fluid's progress from licensing to commercialization.
Blenders and Rebranders involved in the production and sale of GPP® registered products must be licensed and undergo a range of product testing prior to final licensing. Licensed product brands are periodically audited to ensure that they continue to meet the specification.
