The Coordinating Research Council, Inc. conducted a program in Phoenix, Arizona, to investigate customer perception of hot-weather driveability problems in routine daily service as influenced by changes in gasoline volatility. Using established CRC driving cycles, trained raters also evaluated the hot-weather driveability and vapor lock tolerance of each customer's car. Data were then available to provide relationships between customer and trained rater evaluations. Daily maximum temperatures in Phoenix were consistently above 90 degrees F, and frequently above 100 degrees F. Fifty-five customers were selected for participation in the program, allowing for a wide variety of traffic and driving conditions generally associated with hot-weather driveability problems. The customer-owned vehicles included in the program were 1977-1981 models, most equipped with automatic transmissions. Some light-duty trucks were included, as well as passenger cars. Vehicles were selected to be representative of the current car population, and were given a mechanical check to insure that they were in good running order. Five fuels of varying volatilities were used in the test program.
