Summary:

The viscosity stability of polymer-thickened multigraded oils measured by the sonic oscillator failed to correlate with road test data when polymers of different chemical types were compared. A single cylinder Labeco CLR engine test procedure has been developed which correlates well with road tests and is independent of the chemical type of polymer used. Approximately 40 hr in the Labeco CLR engine are equivalent to 2000 miles of high speed driving
