1963 Pure Oil Performance Trials

Background of the Pure Oil performance trials on six classes of automobiles is presented and the evolution of test requirements described. Three tests are run: the economy test to establish how far a vehicle can go over a prescribed course on one gallon of gasoline; the acceleration test which determines acceleration time from 25 to 70 mph in seconds; and the braking test where stopping distance in feet is measured for a stop from 60 mph. Each test is described from the point of view of rules, recording instruments, and penalties for infractions of rules. Test results are presented.
