Frequently Asked Questions About Indiana Gas Prices
What is the average gas price in Indiana right now?▾
Gas prices in Indiana are updated weekly. Check back soon for the latest statewide average, or browse our city pages for the most current local data. Historically, Indiana prices track closely with the Midwest regional average.
What is the gas tax in Indiana?▾
Indiana charges approximately 56.3 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 74.7 cents per gallon. Indiana's state tax is higher than the national average, which contributes to elevated pump prices statewide.
When is the cheapest day to buy gas in Indiana?▾
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 Indiana, 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 Indiana gas compare to neighboring states?▾
Indiana borders illinois, ohio, kentucky, 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. Indiana's PADD 2 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 Indiana?▾
Gas prices in Indiana react to several factors: crude oil futures (the biggest driver), local refinery output, seasonal fuel blend mandates, transportation costs to Indianapolis, 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 Indiana?▾
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 Indiana. Avoid gas stations directly off major interstates, which typically charge a convenience premium.
Does Indiana require reformulated gasoline?▾
Yes, parts of Indiana — particularly densely populated metro areas — are required to use reformulated gasoline (RFG) under EPA clean air standards. RFG burns cleaner but costs slightly more to produce, which adds a few cents per gallon versus conventional gas.
What fuel grade should I use for my car in Indiana?▾
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 Indiana
Gas prices in Indiana are influenced by several regional factors including proximity to refineries, pipeline infrastructure, state regulations, and seasonal fuel blend requirements. Indiana sits in the PADD 2 supply region (Midwest), which means local prices largely trackMidwest refinery output.
The Indiana state excise tax of 56.3¢ per gallon is among the highest in the nation, adding approximately $0.56 to every gallon sold at the pump. On a 15-gallon fill-up, Indiana drivers pay about $11.20 in combined state and federal fuel taxes.
Prices vary significantly across Indiana's cities and regions. Urban areas like Indianapolis 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.
