Motor Fuels

Consumers in Arizona purchase nearly 7.9 million gallons of gasoline daily at approximately 2,100 fuel dispensing sites, utilizing over 72,000 individual fuel dispensers. In addition, several million gallons of fuel, such as diesel and ethanol flex fuel are also dispensed from these locations daily.  The Weights and Measures Services Division (WMSD) is responsible for investigating and auditing fuels throughout their lifespan, from refineries and pipelines to storage terminals and delivery trucks and finally to fuel dispensing sites and retailers.
