All petroleum products sold in the state must be registered with MDAC’s Petroleum Products Inspection Division. All retail motor fuel products which include gasoline, ethanol blended fuel, diesel fuel, biodiesel blended fuel, and kerosene, are analyzed by the Mississippi State Chemical Lab to ensure product compliance within American Society for Testing and Materials (ASTM) specifications. Analysis includes tests for octane number, alcohol content, diesel flash point, biodiesel content, and the presence of water in fuel.

The Division regulates approximately 2.3 billion gallons of fuel consumed by Mississippians and visitors to the state and conducts annual inspections of the Retail Motor-Fuel Dispensers (RMFD), commonly known as gas pumps, to ensure compliance with all laws and regulations. These inspections consist of ensuring the accuracy of RMFDs, testing for the presence of water, checking signage to ensure that the proper price is displayed on all signs, and checking the quality of the fuel to ensure proper product designations. Violations are issued for equipment found to be out of compliance with the petroleum law. Petroleum equipment repairmen are required to obtain a license from MDAC and report all adjusted devices to the Division.
