This basis was developed by determining the average viscosity changes of one single grade and twelve multigrade reference oils in six separate car fleets. The twelve multigrade oils were formulated with all of the chemical types of VI improvers currently in use, or likely to be used, in the near future.Lubricating oilsTestingShear (Mechanics)Lubricating oilsTesting.Shear (Mechanics)629.255ASTM Committee D02 StaffPQKBBOOK9910161633003321Shear Stability of Multigrade Crankcase Oil2138707UNINA
