Sommario/riassunto |
|
Extensive field test data have been obtained which can serve as a basis for evaluating the ability of various laboratory methods to predict the shear stability of multigrade crankcase oils. 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. |
