Leaded premium (0.15 g Pb/l) and unleaded Eurograde motor fuels have been examined in respect of the limits for borderline knock in five cars. The fuels consisted of gasoline with only hydrocarbons and gasoline containing ethanol, methanol/butanol and ethanol/MTBE respectively corresponding to 2 % oxygen by weight. Under acceleration circumstances the oxygenated fuels indicated slightly better resistance to knock. At constant speed/full load (less than 4000 rpm) all the fuels are considered to be equilvalent. At higher engine speeds a tendency towards a slighlty inferior knock margin can possibly be traced for the E 5.5 fuel, although the margin remained satisfactory. The results indicate that the octane number raising effect of the oxygenates should be utilizable to the full.
