Viscosity in Grease Selection

19 Aug 2019, Posted by cnewman@mcphersonoil.com in General

Because grease is 80%-90% oil, the viscosity of the base oil is important.  The higher the viscosity, the greater the resistance to flow.  Lower viscosity oils have less resistance and flow quickly.  Why is this important?  The goal of lubrication is to separate metal surfaces with a film of oil just thick enough to prevent metal to metal contact.  If the film is too thin, it causes contact between the metals resulting in wear.  If the viscosity is too high, it causes excessive drag which results in reduced efficiency and excess heat. Take a look at this video from our partners at ExxonMobil to see more of why viscosity matters in grease selection.
