The States With the Cheapest Gas Prices
Although a far cry from the highest recorded average prices seen in June 2022, gas is still expensive and remains a major financial strain on American drivers.
As of Mar. 22, the AAA national average cost for regular unleaded gasoline was $3.436 and for diesel, $4.279. On the same date, the average prices for regular gasoline ranged from a low of $2.984 in Mississippi to a high of $4.832 in California.
According to the U.S. Energy Information Administration (EIA), there are a lot of factors contributing to the wide range of gas prices seen throughout the country — including differences in state taxes and legislation, distances from supply, supply disruptions and retail competition and operating costs.
When it comes to California, its perennial high gasoline prices stem from a very high demand and its strict environmental regulations that require drivers to use a unique blend of cleaner, low-emission fuel (California Reformulated Gasoline [CaRFG]).
The Sunshine State has the worst traffic congestion and the busiest roads in the U.S., per car subscription platform Finn. When a California refinery has an operating problem or a dip in production, pricey replacement supplies need to be sourced from out of state, U.S. Gulf Coast or foreign refineries. The state gas tax is quite substantial, as well.
Nipping at California’s heels is Hawaii ($4.822), where gas prices have increased the most out of any state over the past 10 years, then Washington ($4.239). At the other end of the gas price spectrum, Mississippi has the cheapest gas in the U.S. today, at $2.984, followed by Oklahoma at $2.999 and Arkansas at $3.035.
