5 Shocking Facts About Gasoline Prices In 1978: The Calm Before The $3.20 Storm
For many Americans, the year 1978 is remembered as a brief period of economic stability, a moment of respite between two major global energy crises. While inflation was a concern, the cost of filling up your tank was remarkably cheap by today's standards, creating a false sense of security before the market chaos that was about to unfold.
As of late December 2025, the price of gasoline is a constant topic of discussion, but looking back at 1978 reveals a fascinating—and volatile—chapter in U.S. economic history, where the average price per gallon was less than a dollar, yet the seeds of the next massive oil shock were already being planted on the other side of the world.
Fact 1: The Average Price Was Astonishingly Low (In Nominal Dollars)
In the United States, the average retail price for a gallon of regular unleaded gasoline throughout 1978 was a figure that seems almost unbelievable to modern drivers. The cost hovered in a narrow, stable range for most of the year, especially when compared to the dramatic spikes of the earlier 1973 crisis or the impending disaster of 1979.
The 1978 Price Snapshot
- Average Price Per Gallon: The annual average price for all types of gasoline in 1978 was approximately $0.652 per gallon.
- Monthly Range: For regular unleaded gasoline in U.S. cities, the price typically ranged from 65 cents to 71 cents per gallon.
- The Calm: This period represented a relative calm in the market, with prices remaining fairly flat, especially during the first three quarters of the year. The slight increases seen toward the end of 1978 were merely a prelude to the massive spike that began in early 1979.
This stability was a crucial factor in the perceived affordability of driving, allowing American consumers a temporary reprieve from the economic anxieties that had defined the mid-1970s.
Fact 2: The 1978 Price Is Equivalent to Over $3.00 Today
The most important context for understanding the 1978 price is adjusting it for inflation. While 65 cents sounds incredibly cheap, the purchasing power of the U.S. dollar was significantly higher back then. Accounting for four decades of inflation paints a much clearer picture of the actual cost burden on the average consumer.
The Inflation-Adjusted Cost
- Adjusted for Inflation (2025 Dollars): The average 1978 gasoline price of around $0.63 per gallon translates to approximately $3.20 per gallon in current (2025) dollars.
- Real Cost Comparison: This inflation-adjusted price is surprisingly close to what many Americans pay today, demonstrating that while the nominal price has increased dramatically, the *real* cost of gasoline, relative to other goods and wages, has remained within a comparable range over the long term.
The comparison highlights that the perceived "cheapness" of 1978 gas was an illusion created by a lower overall cost of living. The $3.20 figure in today’s purchasing power is a powerful reminder that the economic pressure on drivers has always been significant.
Fact 3: The Iranian Revolution Began the Year's Price Volatility
The single most important geopolitical event that shattered the stability of the 1978 oil market was the Iranian Revolution. While the full impact—known as the Second Oil Shock—was felt in 1979, the seeds of the crisis were sown in the autumn of 1978.
The Geopolitical Trigger
- Oil Field Strikes: Strikes began in Iran's crucial oil fields in the fall of 1978.
- Crude Oil Export Halt: By January 1979, Iran's crude oil exports had essentially stopped.
- 1978 Impact: Although the full price shock came later, the market began to react to the growing instability and supply fears in late 1978. The price of crude oil, which directly dictates gasoline costs, was already moving upward by the end of the year in anticipation of the supply disruption.
The Iranian Revolution was a game-changer. Iran, a major global oil exporter, suddenly removed a significant volume of crude oil from the world market. This led to widespread panic, precautionary demand hoarding, and a rapid, massive escalation in global oil prices throughout 1979, effectively ending the period of relative calm experienced in 1978.
Fact 4: OPEC's Role Was Set for a New Price War
The Organization of the Petroleum Exporting Countries (OPEC) played a central, though complex, role in the 1978 market. Having successfully used an oil embargo to dramatically raise prices during the 1973 Oil Crisis, OPEC's power was well-established.
In 1978, OPEC was operating in a market that was tightening due to global economic growth and increasing demand. The impending loss of Iranian oil gave the cartel the leverage it needed to further increase prices, solidifying its position as a dominant force in the global energy landscape.
Key Market Entities and Factors
The price of gasoline in 1978 was influenced by a confluence of factors and key entities:
- OPEC: The primary entity controlling a large portion of the world's crude oil supply.
- U.S. Bureau of Labor Statistics (BLS): The source for the official city average price data.
- Inflation: Driven by broader U.S. monetary and fiscal policy, which eroded the dollar's purchasing power.
- U.S. Energy Policy: Efforts to increase domestic fuel economy and reduce reliance on foreign oil were ongoing, but had not yet fully insulated the country from global shocks.
Fact 5: 1978 Was the Last Year of True Affordability Before the 1979 Chaos
Looking back, 1978 stands out as the final year of what might be called "predictable" gasoline prices for the 1970s. The entire year served as a quiet, final chapter before the massive economic disruption of the Second Oil Shock.
In the wake of the Iranian Revolution, the price of crude oil—and therefore gasoline—more than doubled between April 1979 and April 1980. This led to widespread gas rationing, long lines at the pump, and a period of intense economic stagnation known as "stagflation" (high inflation coupled with slow economic growth).
For this reason, the 65-cent average of 1978 is a significant historical marker. It represents the end of an era—a brief, financially manageable moment for American drivers before they were plunged into the volatility and shortages that defined the end of the decade and forever changed the relationship between the U.S. economy and global energy markets.
