At an increased level of 0.25% K-CORR 1031, improvement in theFour Ball Wear performance, similar to that shown on the previous page, is demonstrated.Additive CompatibilityA concern exists regarding the compatibility of ashless and metal-containing (primarily zinc)lubricants and functional fluids. Formulations containing K-CORR 100 Series rust inhibitors,particularly K-CORR 1031, are tolerant of contamination with zinc dithiophosphate-based fluids.Studies showing this behavior are available.Pages 33-34
