Ground systems present a great opportunity for fleet managers to reduce cost and increase system availability. The oils in production today allow for many vehicles to use condition based maintenance to increase oil change intervals. Along with increasing change intervals a well thought out condition monitoring system has the potential to detect major system failures, allowing fleet managers to mitigate potential failures at a reduced cost, and on a schedule. Remember one engine, or transmission failure avoided will pay for years of oil analysis conducted, even on small fleets of vehicles
