Fuel Quality Program
Who We Are and What We Do
This program is responsible for the inspection, analysis and enforcement of fuel quality standards 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 inspect retail stations to ensure proper labeling and blending, and ensure fuels are not exposed to conditions that would compromise their quality.
Fuel Quality Sampling & Inspections
Three Fuel Quality Inspectors sample hundreds of retail locations yearly. Samples of fuel are obtained from retail fueling stations, and fuel distributors facilities. Inspectors measure storage tanks for water, check dispenser labeling, ensure products are blended correctly, ensure proper filters are installed on dispensers, and inspect product transfer documents.
Retail Fuel Dispenser Labeling
Product labeling on the dispenser is intended to inform the consumer of what type of fuel and grade they are purchasing. Improper labeling or lack of labeling could confuse or mislead the consumer. For this reason, federal and state regulations require specific dispenser labeling of different products sold to the consumers.
Fuel Quality Testing
Missouri is one of approximately 14 states that have a robust fuel quality-testing program. Our fuel quality requirements and laboratory methods are based on the latest ASTM standards and we are fortunate to have a fully equipped fuel laboratory that is held in high regard by industry leaders and consumers alike.
The Fuel Quality Lab performs more than 20 different chemical and visual analyses to ensure Missouri consumers are purchasing quality petroleum products. These efforts provide economic benefits in terms of increased vehicle fuel efficiency, decreased vehicle maintenance costs, and also help promote better air quality.
