Why Gas Prices Vary by State
Gas prices differ across states due to four main factors: state gas taxes (ranging from 8.95¢/gal in Alaska to 68.1¢ in California), distance from refineries (Gulf Coast states pay less because fuel travels shorter distances), fuel blend requirements (California's CARB standards add 30-50¢/gal), and local competition (markets with more stations tend to have lower prices).
The federal gas tax of 18.4¢ per gallon applies uniformly across all states. The prices shown above reflect regional averages from the EIA and include all taxes.
How to Find the Cheapest Gas in Your State
State averages mask significant local variation. Within a single ZIP code, the cheapest and most expensive stations can differ by 30-50¢ per gallon. To find the actual cheapest gas near you, search your ZIP code for real-time station-level prices with driving distances.
Warehouse clubs (Costco, Sam's Club) consistently price 15-25¢ below street price. Grocery fuel programs (Kroger, H-E-B) offer loyalty discounts of 5-20¢ per gallon. Filling up mid-week (Tuesday-Wednesday) typically saves 3-5¢ versus weekend prices.
Frequently Asked Questions
Which state has the cheapest gas?
Minnesota currently has the cheapest gas at $3.42 per gallon. Gulf Coast and Midwest states (Oklahoma, Kansas, Arkansas, Missouri, Texas) consistently have the lowest prices due to proximity to refineries and low state taxes.
Which state has the most expensive gas?
Washington currently has the most expensive gas at $5.19 per gallon. West Coast states pay more due to strict fuel blend requirements (CARB standards), high state taxes, and limited pipeline access.
Why do gas prices vary so much between states?
Four factors drive state-by-state price differences: state gas taxes (8.95¢ to 68.1¢ per gallon), distance from oil refineries (Gulf Coast states are cheapest), fuel blend requirements (California's CARB standards add 30-50¢), and local station competition. The federal tax of 18.4¢/gal is the same everywhere.
What is the national average gas price right now?
The current estimated US average is $3.91 per gallon for regular unleaded. This is based on EIA regional price data, which updates weekly.
