How Texas Diesel Prices Are Measured
Diesel prices come from two independent sources that measure differently:
AAA Daily Average
Based on over 100,000 gas stations nationwide. Updated daily using actual pump prices reported by stations and credit card transaction data.
- Update frequency: Daily
- Granularity: State-level (all 50 states + DC)
- Methodology: Station-reported pump prices
EIA Weekly Survey
Published by the U.S. Energy Information Administration. Texas falls within PADD 3 - Gulf Coast, one of five Petroleum Administration for Defense Districts (PADDs).
- Update frequency: Weekly (Mondays)
- Granularity: State-level
- Methodology: Volume-weighted survey of ~900 retail outlets per region
Why do AAA and EIA prices differ for Texas?
Texas is one of only 9 states where the EIA publishes state-specific diesel data (the others are California, Florida, New York, Ohio, Minnesota, Colorado, Massachusetts, Washington). Even so, AAA and EIA prices can differ by $0.05–$0.30 due to different survey methodologies, sample sizes, and reporting timeframes. AAA captures daily pump prices from a larger station sample, while EIA uses a smaller, volume-weighted weekly survey. Our API provides both sources so you can choose the methodology that best fits your use case.
