Indiana gas prices
Indiana is one of the cheapest Midwest states for gas. The biggest reason is the BP Whiting refinery in northwest Indiana, one of the largest in the country. That single facility produces a huge volume of gasoline and diesel for the region. Having a major refinery right in state keeps supply robust and prices competitive.
The state also has relatively low gas taxes compared to neighbors like Illinois and Michigan. Indiana is a major crossroads for interstate trucking, with I-65, I-70, and I-69 all running through the state. Competitive truck stops along these corridors help keep prices in check for both gasoline and diesel.
Price history
Why is gas cheaper in Indiana than Illinois?
Two big reasons. Indiana has lower gas taxes, and the BP Whiting refinery in northwest Indiana produces enormous volumes of fuel right in state. Illinois, especially Chicago, adds high local taxes and requires a special fuel blend.
What is the BP Whiting refinery?
It's one of the largest refineries in the Midwest, located in Whiting, Indiana, just south of Chicago. It processes about 440,000 barrels of crude oil per day and is a major source of gasoline and diesel for the entire Great Lakes region.
How do Indiana diesel prices compare nationally?
Indiana diesel is usually below the national average thanks to the Whiting refinery and competitive truck stop pricing along major interstates. Fleet operators running through the Midwest often plan fuel stops in Indiana for this reason.
