Abstract (en)
[origin: EP1568758A2] Compositions and methods are disclosed for providing anti-shudder performance in power transmission fluids through the incorporation of a non-dispersant viscosity index improver. Further, the disclosed compositions achieve improved compatibility of an elastomeric component with a lubricating fluid through the incorporation of a non-dispersant viscosity index improver.
