Historical Gas Prices
August 31, 2015
In the first six months of 2015, the average retail price of regular gasoline was $2.49 per gallon—the lowest average price since the economic recession in 2009. Gasoline has always been subject to price swings but the degree of price volatility has increased since the mid-1970s. Between 1930 and 2015, the average price of regular gasoline has ranged from a low of $1.43 per gallon in 1998 to a high of $3.69 per gallon in 2012 when measured in constant 2015 dollars. The effect of the U.S. embargo of Iranian oil can be seen in the early 1980's with the price of gasoline peaking in 1982.
