WebbThe critical scuffing temperature for mineral oils without anti-scuffing or extreme pressure additives increases directly with viscosity and varies from 150 to 300C (300 to 570F). However, this increased scuffing resistance appears to be directly attributed to differences in chemical composition and only indirectly to the beneficial effects of increased film … WebbJSTOR Home
