How California Gasoline Prices Are Measured

Gasoline 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. California falls within PADD 5 - West 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

California is an EIA State-Reported Market

California is one of only 9 states where the EIA publishes state-specific gasoline data (the others are Texas, Florida, New York, Ohio, Minnesota, Colorado, Massachusetts, Washington). This means our API can provide more precise regional data for California alongside the AAA daily average. Even state-level sources can differ by $0.05–$0.30 due to different survey methodologies, sample sizes, and reporting timeframes.
