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. 606 $aLubricating oils$xTesting 606 $aShear (Mechanics) 615 0$aLubricating oils$xTesting. 615 0$aShear (Mechanics) 676 $a629.255 712 02$aASTM Committee D02 Staff 801 0$bPQKB 906 $aBOOK 912 $a9910161633003321 996 $aShear Stability of Multigrade Crankcase Oil$92138707 997 $aUNINA
