GREENVILLE, SC (FOX Carolina) -
Gas prices in the Greenville area increased 2 cents during the past week, according to GasBuddy.com.
The price-tracking website reported the average cost for a gallon of gas in the Greenville area was $3.12 - 19 cents lower than the national average.
Locally, the price was 4.5 cents higher than last month, but 11.2 cents lower than last year. Nationally, the price was also 4.5 cents more than last month, but 6.7 cents lower than last year.
Experts attribute the slight increase in a period of refinery maintenance.
"Refinery production has taken a hit in the last week as companies begin looking towards the summer driving season, utilizing this time of year for maintenance and any upgrades before gasoline demand races higher for the summer season," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.
AAA reported the average cost for a gallon of gas was at $3.19 in South Carolina, $3.37 in North Carolina and $3.32 in Georgia.
Hawaii had the nation's most expensive gas, while Wyoming had the nation's cheapest.
