Interrelationship among viscosity, temperature and age of lubricant

Abstract

Purpose

To provide a general equation for finding out viscosity of lubricating oils at different temperatures and ages.

Design/methodology/approach

Based on previous works and a case study on field, a general equation was formulated which relates viscosity‐temperature‐age of lubricant.

Findings

The equation is very simple and a good consistency was found.

Practical implications

This equation will help the designers/manufacturers to recommend the correct grade of lubricating oil.

Originality/value

This type of relationship was never reported earlier.
