Abstract (en)
[origin: US2008176775A1] Methods for achieving favorable efficiency properties are disclosed including methods for blending a lubricant composition and lubricant compositions. In one embodiment, the method comprises the steps of obtaining at least one base stock and at obtaining at least one base stock chosen to have a favorable air release properties, obtaining at least one additive, blending at least one base stock and at least one additive to achieve a favorable effective bulk modulus through air release property, bulk modulus, and using a relationship between density and bulk modulus.
