Full-Throttle Modified Uniontown Road Octane Numbers (Road ON) were obtained by twelve participating laboratories in thirty-seven cars that represent twenty-four different 1980 makes and models, one 1979 model, and one 1981 model. Part-throttle Road ON ratings were obtained by four participating laboratories in twelve cars representing nine different 1980 makes and models. The data were analyzed using multiple linear regression and analysis of variance techniques. Analyses were made on all-car average data, as well as data from individual cars and from several subgroups. The all-car data did not show a significant ethanol-content effect, but eight of the thirty-seven cars did show significant effects. Analysis of variance showed that fuels had the largest effect on full-throttle Road ON. Cars had smaller, but highly significant, effects. The effects of fuels on Road ON varied among the cars.
