According to data from the American Automobile Association (AAA) as of January 2023, the average diesel price in the state of Georgia was around $3.89 per gallon. Barnesville is located in Lamar County, Georgia, and diesel prices in rural areas tend to be slightly lower than in larger cities. Therefore, you might find diesel prices in Barnesville to be around $3.80 to $3.85 per gallon.
However, it's important to note that fuel prices can fluctuate rapidly and may have changed significantly since January 2023. For the most up-to-date and accurate diesel prices, I recommend checking reputable sources such as GasBuddy, AAA, or local gas station websites.
