OCTANE REQUIREMENT TRENDS OF EUROPEAN AND JAPANESE CARS
Japanese cars typically exhibited lower octane requirements than their European counterparts, but the octane requirement of some Japanese cars could be reduced by careful control of ignition advance characteristics. Moreover, recent engine designs appeared to be a little less sensitive to fuels having high delta RON (100C) valves. Forty-five percent of the critical car models were highly conscious of the sensitivity and/or olefin content of gasolines at high engine speeds. Of these, 52 percent differentiated by more than one RON between fuels containing 0.4 g Pb/litre and 0. 15 g Pb/litre, particularly under high-speed acceleration testing.
