Beschreibung
Zusammenfassung:	The air release rate of lubricating compositions is significantly enhanced when the composition is formulated with alkyl salicylate detergents, especially calcium or magnesium alkyl salicylate detergents. Compositions having the improved air release rates are substantially free of a viscoelastic fluid having a shear stress greater than 11 kPa and a viscosity greater than 30 cSt at 100°C. La vitesse de désaération de compositions lubrifiantes est notablement améliorée lorsque la composition est formulée avec des détergents salicylate alkyle, notamment des détergents salicylate alkyle de calcium ou de magnésium. Des compositions présentant les vitesses de désaération améliorées sont sensiblement exemptes de fluide viscoélastique dont la contrainte de cisaillement est supérieure à 11 kPa et la viscosité dépasse 30 cSt à 100°C.
