Frequently Asked Questions About Oklahoma Gas Prices
What is the average gas price in Oklahoma right now?▾
Gas prices in Oklahoma are updated weekly. Check back soon for the latest statewide average, or browse our city pages for the most current local data. Historically, Oklahoma prices track closely with the Gulf Coast regional average.
What is the gas tax in Oklahoma?▾
Oklahoma charges approximately 19 cents per gallon in state excise taxes on gasoline. The federal gas tax adds another 18.4 cents per gallon, bringing the combined tax burden to roughly 37.4 cents per gallon. Oklahoma's state tax is below the national average, which helps keep pump prices relatively low.
When is the cheapest day to buy gas in Oklahoma?▾
Nationally, Monday and Tuesday tend to offer the lowest gas prices, while Friday and Saturday are often the most expensive as weekend demand rises. In Oklahoma, patterns follow similar trends. Prices also fluctuate based on crude oil markets, which reset each week. Checking prices early in the week can save you several cents per gallon.
How does Oklahoma gas compare to neighboring states?▾
Oklahoma borders kansas, colorado, new mexico, and prices across state lines can vary by 5–30 cents per gallon depending on each state's gas tax, refinery access, and local competition. Oklahoma's PADD 3 regional supply chain primarily influences local prices. Drivers near state borders may find it worthwhile to cross state lines for a fill-up if price differentials are significant.
Why do gas prices change so frequently in Oklahoma?▾
Gas prices in Oklahoma react to several factors: crude oil futures (the biggest driver), local refinery output, seasonal fuel blend mandates, transportation costs to Oklahoma City, and local retailer margins. Prices typically update weekly or more frequently when crude markets are volatile. Summer-blend gasoline, which is more expensive to produce, also raises prices from spring through Labor Day.
How can I find the cheapest gas station in Oklahoma?▾
Use our station finder on any city page to see real-time prices at nearby stations. Apps like GasBuddy can also show crowdsourced prices. In general, warehouse clubs (Costco, Sam's Club) and hypermarket fuel centers (Walmart, Kroger) consistently offer prices 5–15 cents below branded stations in Oklahoma. Avoid gas stations directly off major interstates, which typically charge a convenience premium.
Does Oklahoma require reformulated gasoline?▾
Some metro areas within Oklahoma may have seasonal or year-round reformulated gasoline requirements under EPA standards. Check the EPA's RFG locator for specific Oklahoma counties. Outside designated RFG areas, conventional gasoline is sold at lower cost.
What fuel grade should I use for my car in Oklahoma?▾
Most vehicles on the road today are designed for regular 87-octane unleaded gasoline. Check your owner's manual — only use premium (91+) if your vehicle requires or recommends it. Using premium when regular is specified wastes money without performance benefit. Midgrade (89 octane) is rarely the optimal choice for any modern vehicle.
Understanding Gas Prices in Oklahoma
Gas prices in Oklahoma are influenced by several regional factors including proximity to refineries, pipeline infrastructure, state regulations, and seasonal fuel blend requirements. Oklahoma sits in the PADD 3 supply region (Gulf Coast), which means local prices largely trackGulf Coast refinery output.
The Oklahoma state excise tax of 19¢ per gallon is among the lowest in the nation, adding approximately $0.19 to every gallon sold at the pump. On a 15-gallon fill-up, Oklahoma drivers pay about $5.61 in combined state and federal fuel taxes.
Prices vary significantly across Oklahoma's cities and regions. Urban areas like Oklahoma City tend to have more competition between gas stations, which can keep prices closer to the state average. Rural areas may see prices 10–20¢ higher due to fewer competing stations and higher delivery costs.
