MAXIMIZING PETROLEUM UTILIZATION THROUGH EXTENSION OF PASSENGER CAR OIL DRAIN PERIODS-WHAT'S REQUIRED

A study was made of passenger car engine oil drain intervals from 1946 to the present time. The drain intervals were intercompared with engine tests used to guage oil performance and trends in automotive emission control. Taxicab data show that higher quality levels then current API SE are needed to double today's recommended oil change intervals. Engine wear appears to be the major technical limitation on extending oil change intervals. Other technical limitations are control of engine deposits and resistance to oil thickening. /GMRL/
