Fuel Quality Program
This program administers the fuel quality law through inspection, analysis and enforcement to help ensure consumers are purchasing quality motor fuels. Fuel samples are collected by field personnel and submitted for testing. The petroleum laboratory analyzes gasoline, kerosene, heating fuels, diesel fuels and alternative fuels including biodiesel and E85 fuel ethanol to make certain they meet state quality and safety standards. Field personnel also inspect filling stations and fuel terminals to ensure proper labeling and blending, and ensure fuels are not exposed to conditions that would compromise their quality. The fuel quality program is also responsible for administering and enforcing the Missouri Renewable Fuel Standard Act. With several exceptions, the Act provides that effective January 1, 2008 all gasoline sold or offered for sale in Missouri at retail shall be fuel ethanol-blended gasoline (90% gasoline and 10% fuel ethanol). Stakeholder input was instrumental in developing rules and regulations for the Act.
Fuel Quality Program Description
No one wants water or any other foreign substance in their gasoline. That’s why the Missouri Weights, Measures and Consumer Protection Division is responsible for assuring that all motor fuels and other fuels meet minimum quality specifications. Through a vigorous program of inspection, sampling, and testing, the division protects Missouri consumers of petroleum fuels and products. The direct benefits are twofold: First, economic benefits are derived from consumers receiving quality products and services, especially in the areas of fuel quality, vehicle efficiency, and vehicle maintenance. Second, by monitoring compliance with air pollution control program and fuel quality specifications, the division promotes better air quality and more efficient fuel use.
Missouri’s Fuel Quality Law can be found in Chapter 414 of the Revised Missouri Statutes. Rules and regulations regarding fuel quality can be found in the Code of State Regulations, 2 CSR 90-30.040 (Select Chapter 30) Quality Standards for Motor Fuels. Most of the fuel quality regulations follow quality and testing standards developed by ASTM International (ASTM) Committee D-2 on Petroleum Products and Lubricants.
The ASTM is a national voluntary consensus standards organization that develops and promotes standards on characteristic and performance of materials, products, systems, and services. Members include producers, end users, and governmental regulatory agencies.
Examples of ASTM specifications referenced by the regulations are:
- D4814 Standard Specification for Automotive Spark-Ignition Engine Fuel
- D910 Standard Specification for Aviation Gasoline
- D1655 Standard Specification for Aviation Turbine Fuel
- D975 Standard Specification for Diesel Fuel Oils
- D396 Standard Specification for Fuel Oils
- D3699 Standard Specification for Kerosine
- D5798 Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines
- D6751 Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels
- D4806 Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel
- D6227 Standard Specification for Grade 82 Unleaded Aviation Gasoline

Fuel Quality Program History
Missouriís first responsibility for ensuring fuel quality came on February 18, 1865, when the governor was required to appoint an inspector of coal oil, petroleum oil, or any mixture of the two for the city of St. Louis. The inspector was to examine and test the quality of all coal or petroleum oils and to brand them "approved" or "rejected".
At that time, the fuel was used for illuminating purposes and only a flash point test was conducted. Today, the Fuel Quality Program conducts numerous tests on other types of fuels used for many other purposes.
The fuel quality program is located in Jefferson City at the Petroleum Laboratory. Samples are obtained by unannounced inspections, consumer complaints, and other requests.
