Gas prices today May 17: Check daily average rates in California, Texas, Florida, New York, Washington and more

The latest data from American Automobile Association shows the US national average price for regular gasoline at $4.513 per gallon as of May 17, 2026. After a brief dip earlier in the week, pump price changes are almost moving flat, with small increases in some states.

While daily shifts may seem modest, the broader trend remains one of persistent regional differences. West Coast and non-contiguous states still post the highest prices, while parts of the South and Midwest continue to offer relatively lower costs. Supply chain dynamics, refinery utilization, fuel taxes, and environmental fuel standards are all contributing to this uneven landscape.
