For a conventional gasoline engine, the higher the compression ratio, the more efficient the engine. US passenger cars have not had very high compression ratios for about 30 years for multiple reasons. During 1970-1972, Chrysler had the highest compression ratios in US production cars, requiring the highest octane gasoline to operate properly.
