Title:
完成潤滑剤の形成方法
Document Type and Number:
Japanese Patent JP2011506676
Kind Code:
A
Abstract:
A method for forming a finished lubricant comprises selecting a target high temperature viscosity for the finished lubricant. A target high temperature viscosity for a base oil blend is selected. The target high temperature viscosity for the base oil blend is less than the target high temperature viscosity for the finished lubricant. At least two base oils from at least three viscosity grades of base oils are selected and mixed to form a base oil blend that meets the target high temperature viscosity for the base oil blend. The base oil blend is mixed with performance additive package and viscosity modifier to provide a finished lubricant that meets the target high temperature viscosity for the finished lubricant. The at least two base oils for the base oil blend having the target high temperature viscosity are selected such that less viscosity modifier is needed to meet the target high temperature viscosity of the finished lubricant.
