Octane requirement increase (ORI) was determined for sixty-two 1984 model cars and trucks operated on unleaded gasoline. The cars tested were not selected to represent the distribution of vehicles produced in the model year; rather the data base consists of information volunteered by participants. All ORI values were determined from the increase in maximum octane requirements irrespective of whether requirements were obtained at full- or part-throttle. Though the sample size is smaller than in previous years, it does not appear to have significantly affected the conclusions. Contents: Vehicles Tested; Mileage Accumulation; Average Sensitivity Full-Boiling Range Unleaded Reference Fuel (FBRU); High Sensitivity Full-Boiling Range Unleaded Reference Fuel (FBRSU); Primary Reference (PR) Fuel; Test Technique; Data Analysis Technique; Comparison of 1975 through 1984 ORI Studies; ORI Versus Initial Octane Requirements.
