Gasoline and operating factors affecting the vapor locking tendency of European cars have been studied. Three different test procedures were employed: one, similar to the CRC procedure, was shown by a consumer reaction test to induce vapor lock at ambient temperatures at least 11 F lower than required in normal service. The variation in vapor locking tendency for cars of a given make and model had a standard deviation of 0.61 lb RVP. The tendency of a gasoline to give vapor lock was predicted better by a combination of RVP and front end slope than by some other volatility expressions.Gasoline and operating factors affecting the vapor locking tendency of European cars have been studied.
