This paper characterizes the features and describes some of the benefits of the present generation of multigrade “MS” oils. Particular emphasis is placed upon viscosity retention characteristics as a function of the stability of the viscosity index improver.
Comparative automobile field tests in private commuter, taxicab, and highway service are shown for both SAE 10W-30 and a carefully compounded SAE 10W-40 oil. Observations of cylinder and piston ring wear, crankcase deposits, PCV valve cleanliness, and oil economy are reported.
