Source : Viscosity Oil Company Turf equipment operates under more severe conditions then your average automobile or over the road truck. This means that the selection of lubricants is more important for this category of equipment then others.

Why does a lubricant fail to lubricate Oils lose their desired properties L u b r ic a n t P r o b l e m Why What Happens They can lose their ability to resist oxidation. This is caused when the additives to control oxidation are used up. This can be noticed by an increase of oil viscosity, deposits may form and/or acids may begin to corrode the metal parts. Rust inhibitors are used up and the metal is not protected from further rusting. The oil may lose its ability to protect the metal components from damage caused by heavy operational loads. The additives that keep contaminants in suspension can also be used up. Most of these additives are consumable additives. That means that in the course of doing their job they are consumed or depleted. Oxidation Control Rust Inhibition Inhibitors used up, stopping attack Oil Viscosity increases; deposits on oil and additives form.
