Title: 1975 CRC fuel rating program: road octane performance in 1975 model cars

Abstract

The effects of fuel variables on road antiknock performance in 1975 model cars are evaluated. A 13-fuel Box-Behnken design set was used. Twelve of these fuels comprised a fractional factorial design to investigate the independent variables of Motor octane number (MON), sensitivity (RON-MON), and volume percent aromatics (AROM) at three levels each. The thirteenth fuel was a center point fuel (CPF) included as a check on linearity of road octane number response to the design fuel variables. Three RMFD full boiling range fuels used in the 1975 CRC Octane Number Requirement Survey (CRC Report No. 488), and five unleaded commercial fuels were also evaluated. Full-throttle Modified Uniontown road octane ratings (MUON) were obtained in 37 cars of 22 different makes and models by 9 participating laboratories. Part-throttle Modified Uniontown road octane ratings were obtained in 11 cars of 9 different makes and models by 4 participating laboratories. Laboratory and road octane data are summarized and analyzed.
