Abstract (en)
[origin: WO2008013754A2] A lubricating composition that has improved air release characteristics is based on a lubricating base oil comprising an oil or mixture of oils derived from waxy hydrocarbons produced in an F-T synthesis process. The composition is substantially free of a viscoelastic fluid having a shear stress greater than 11 kPa and a viscosity greater than 30 cSt at 1000C. It is further characterized as entraining less than 1.7% air in 2 minutes and having an air release rate greater than 0.3%/min. when measured at 500C by ASTM D 3427.
