SAN ANTONIO -- Gas prices are changing very fast in some places and remaining high in others. Most of the prices are coming down in the metro area. You may even find drastic price differences within a few block from another station.
Valero says that there are many reasons for the fluctuations, but the trend right now will be lower gas prices due to the lack of demand and the fall season.
Bill Day of Valero said, “We're in the middle of the transition right now between selling summer-grade gasoline -- which is a little bit more expensive -- and selling winter-grade gasoline which is easier to make and less costly.”
Prices can still fluctuate with any adverse uncertainty in the market creating a spike in prices.
“With the election you may see some uncertainty," says Day. "It can be affected by geo-political problems whether it's issues in the Middle East. It can be affected by pipeline outages."
The average price for gas in San Antonio is around $3.40 a gallon.
