A COOPERATIVE study of the relationships between fuel volatility and the cold-starting and warmup performance of late-model passenger cars has been carried out by Standard Oil Co. (Indiana) and Ethyl Corp. Tests were made on seven 1956 passenger cars in an all-weather chassis dynamometer room at ambient temperatures of +40 to −20 F.Fuel volatility was varied over a broad range. Warmup characteristics and sensitivity to fuel volatility varied widely among the cars tested.A comparison of the results of this program with earlier test programs indicated that the modern V-8 engine is more critical to fuel volatility than its in-line predecessors.A COOPERATIVE study of the relationships between fuel volatility and the cold-starting and warmup performance of late-model passenger cars has been carried out by Standard Oil Co.
