This document provides preliminary field data on the performance of FilterMag magnetic filter add-ons used in various industrial and on-road equipment. Across different equipment types including loaders, haul trucks, dump trucks and more, the FilterMag consistently showed an ability to reduce wear-causing particles in engine oil and extend oil change intervals. In lab tests, a FilterMag captured over 5 million wear particles in just one hour of engine break-in operation. The field data demonstrates the FilterMag's effectiveness at enhancing oil cleanliness and protecting engines.
