National regular gasoline averages $4.46 per gallon, while diesel costs $6.44. Indiana regular fuel sits at $3.99, but diesel reaches $6.53.

The national average price for a gallon of regular gasoline reached $4.46 on Friday. Diesel fuel costs averaged $6.44 nationwide. A year ago, regular gas cost $3.20 and diesel cost $3.70. Prices have risen sharply in both categories since last year.

Indiana drivers pay $3.99 per gallon for regular gasoline. This figure is slightly below the national average. Indiana diesel fuel costs $6.53 per gallon. This diesel price is higher than the national average. The state's lower regular gas costs may reflect a temporary tax suspension.

Tax suspension influences state pricing

Governor Mike Braun suspended the state gas tax. The suspension remains in effect through October 6. This policy likely contributes to Indiana's regular gas prices staying under four dollars. Diesel prices remain elevated despite the tax break.

Regional price gaps persist across counties

Southwestern Indiana counties report the lowest fuel costs. Martin and Perry counties average $3.69 per gallon. Orange and Spencer counties average $3.71. Northwestern, northeastern, and southeastern regions show the highest prices. Pulaski County drivers pay $4.29 per gallon.

Political attention on fuel costs

Fuel prices have increased since the start of the Iran conflict. The rising costs have become a political issue ahead of midterm elections. President Donald Trump addressed the topic at a rally in North Carolina. He described the current prices as inexpensive relative to other factors.
