AAA said gas prices have dropped significantly in Tennessee from last week, and Maryville and Knoxville had the highest decline in gas prices with 16 - 12 cents respectively.
The national average fell 5.4 cents to $3.80 last week, as well. The closing price for crude oil on Friday was $92.89 per barrel, which is six dollars less than last week. Some factors responsible for these drops in oil prices include a spike in domestic supply and a lower fuel demand.
The domestic fuel supply jumped by 8.5 million barrels last week, which is the largest gain since March. A report, also from last week, said August's domestic fuel demand dropped to the lowest level in 15 years.
Experts said they are unsure this trend will continue into coming weeks and months. Gas prices could climb because of concerns over hurricane season, effects from the Federal Reserve's stimulus plan and the continuing violence overseas.
