New Study Reveals Cheapest Day to Buy Gas in Indiana

You might want to start planning ahead to fill up your tank on a specific day of the week in Indiana to get the best savings. Here’s what you need to know about the best and worst days to buy gas.

As of this writing (February 24, 2026), the national average for unleaded gas is $2.951, according to AAA. Indiana’s average price per gallon as of today is $2.768. So, we are about 20 cents cheaper than the national average. Thankfully, it’s not as expensive as it was this time last year, when the national average was $3.144, and Indiana’s average price per gallon of unleaded gas was $2.914.That doesn’t mean that some haven’t been feeling the sting of gas prices every time we fill up our tanks. Granted, prices aren’t over $5 like they were a few years ago.

All that said, gas prices change daily. Some days it’s more expensive, and other days, you’ll find better prices. It also depends on which gas station and city you’re filling up in. But there are days that are actually cheaper to buy gas than others, according to a new study by GasBuddy. The company just released a new analysis identifying the cheapest and most expensive days of the week to buy gasoline in all 50 states, based on an analysis of daily statewide fuel prices over the past year. So let’s check out how that looks for Indiana.

The best day to save money on gas will come five to seven days after a price jump. GasBuddy goes on to say that “the gap between buying at the peak of a spike and near the bottom of the cycle can reach 15 to 45 cents per gallon or more, making timing especially important.”…
