With the summer season coming to an end, drivers are enjoying low gas prices.

The national average price for regular gasoline has fallen for the past 22 days, for a total of 28 cents per gallon. Today’s price is $1.05 lower than that of this time last year. AAA predicts that national average will continue to drop. Gas prices tend to drop during the fall and winter seasons when driving decreases. But the end of summer also marks a switch to winter-blend gas.

The Environmental Protection Agency requires certain areas to use a specific blend of gas during summer months in order to address air quality issues. The more expensive summer blend is not required during winter months, adding to dropped costs. AAA predicts these prices to drop through the fall and winter months, falling below $2 per gallon in some parts of the country. Gas prices were relatively high on the West Coast with Torrance’s ExxonMobil’s refinery not operating at normal levels. The refinery is expected to increase production in October.
