Summary:

Octane requirements of late model vehicles were determined by trained knock raters and compared with those determined by customers.Average differences of independent distributions of customer and rater requirements were about 3 Research Octane Numbers/2 Motor Octane Numbers at part-throttle and 6 RON/4 MON at full-throttle and maximum octane requirement conditions.Five percent of the customers objected to knock when their cars were operated on fuel matching rater requirements, while 50 percent objected when using fuel 6 RON/4 MON lower.Another program is planned because differences between rater and customer octane requirements were greater than expected
