Ohio gas prices

Of that gallon of regular, about 59 cents is tax (14%): 18.4 cents federal, 38.5 cents Ohio, and about 2.0 cents of Ohio's Petroleum Activity Tax on the supplier. For diesel it is about 74 cents (11%): 24.4 federal, 47 Ohio, and 2.4 cents of the Petroleum Activity Tax. Ohio charges no sales tax on road fuel.

Before the federal records

No agency published an Ohio pump price before 1970. Ohio newspapers did: station advertisements, price-war stories, and Standard Oil of Ohio's statewide price changes. Found so far, 65 prices from 1912 to 1963; most are one station on one day, not an average.

Every change in Ohio's rate

Where the sources give only a year, only the year is shown. The department lists a cut to 3 cents in 1933 and a return to 4 cents in 1947, but the Federal Highway Administration's tables show Ohio at 4 cents at the end of every year from 1929 to 1952; which is right is not yet settled. From 1981 to 1993 part of the rate was set each year by a formula tied to highway maintenance costs and fuel sales.

Two other Ohio taxes have landed on fuel. From 2005 to mid-2014 fuel sales paid the Commercial Activity Tax; in 2012 the Ohio Supreme Court ruled (Beaver Excavating Co. v. Testa) that money raised on motor fuel may be spent only on roads, and the fuel share was moved into a separate Petroleum Activity Tax on July 1, 2014. It is 0.65% of the supplier's receipts, which works out to roughly one to three cents a gallon depending on wholesale prices.

3. 1942-1945: World War II gasoline rationing (Shortage)

   The federal Office of Price Administration rationed gasoline on the East Coast from May 1942 and nationwide from December 1942 until August 1945. Windshield stickers set allowances: 'A' drivers 2-4 gallons a week, 'B' commuters with 3+ riders 8-10, 'C' essential workers unlimited. A 35 mph 'Victory Speed' limit applied.

   In Ohio: Ohio drivers were under the nationwide program from December 1942. The State Library of Ohio holds a digitized collection of WWII ration certificates and stamps, including gasoline stamps.

4. 1973: Gilligan orders state agencies to cut fuel use (Law or policy)

   The day after President Nixon's Nov. 7, 1973 energy address, Gov. John J. Gilligan ordered every state agency to save fuel, with a goal of cutting state fuel use at least 10 percent. Measures included a 60 mph limit for state vehicles, park-and-ride buses for state workers in downtown Columbus and closing unused rooms. His cabinet energy committee was to report within 10 days on mandatory fuel allocation and lower highway speed limits.

   In Ohio: First state-government response in Ohio to the 1973 embargo; set a 10% state fuel-cut goal and a 60 mph limit for state vehicles.

8. 1973-1974: "Fuel Emergency 50 MPH": Gilligan asks for a voluntary 50 mph limit (Law or policy)

   Without federal or state legislation, Gilligan told Transportation Director J. Phillip Richley to post red-and-white "Fuel Emergency 50 m.p.h." signs on interstates and rural state highways. The limit was voluntary: the patrol could not enforce it until the General Assembly acted. ODOT and U.S. DOT studies put the saving at over 249 million gallons of gasoline a year. Because of the President's call for stations to close from 9 p.m. Saturday to Sunday midnight, Gilligan also started a weekend motorist-aid patrol. It used six courtesy cars and 11 ODOT pickups that siphoned enough gas to reach lodging. Both steps were described as parts of the program of his cabinet-level Ohio Energy Coordinating Council.

15. 1974-1975: Ohio's emergency 55 mph law signed (Law or policy)

    The General Assembly passed a bill setting a 55 mph maximum for cars and trucks, which Gilligan signed. It took effect immediately. The federal Emergency Highway Energy Conservation Act required states to cut speeds by March 3, 1974 or lose over $170 million in federal highway funds. Drivers over 55 but under the old posted limit got a fine and no license points. The emergency law was to expire June 30, 1975 or when Congress declared the crisis over. At the signing, Gilligan said gasoline use in the state was down 17 percent. In earlier committee testimony, Transportation Director Richley had estimated the lower limit would save 115 million gallons a year.

    In Ohio: Mandatory 55 mph in Ohio from early March 1974. The governor reported a 17% drop in statewide gasoline use.

It cited Robert S. Ryan, director of the Ohio Department of Energy, on a projected June shortfall. Causes named: refineries closed for maintenance, farmers' late planting after bad weather, and extra fuel use by truckers who had been on strike earlier that spring.

20. 1979: Rhodes declares "gas-savings week" before Memorial Day 1979 (Shortage)

State officials were to travel to cities to seek local support. To stretch supplies, his administration would ask station operators to consider shorter hours. The paper noted the officials' travel would burn fuel too. This is a voluntary appeal, not rationing: no Ohio odd-even order was found in the sources read.

    Speaking to the Ohio Mining and Reclamation Association at Columbus's Neil House (reported Oct. 10, 1979), Gov. James A. Rhodes called the energy shortage artificial and said the only genuine shortage was one of leadership. He said there would be no gasoline lines if industry and utilities switched from oil to coal. He claimed conversion could save 23% of U.S. oil use, or 4.3 million barrels a day of imports, and backed tax incentives for converting. His answer to the shortage was supply-side coal policy, not rationing.
