Mixed fleets of older and newer trucks from different OEMs present a challenge from a preventive maintenance perspective. But there are flaws in programs that only standardize PM schedules, rely on only one oil for older and newer engines, and forego routine oil analysis.
Oil analysis isn’t just about the condition of in-service oil; it’s an effective way to uncover a host of issues that can impair engine durability and performance. By foregoing routine oil analysis, you are losing that insight and increasing the risk that an undetected problem might eventually lead to equipment failure.
Routine oil analysis will also give you indicators of how much longer the oil is likely to hold up and help establish practical maintenance schedules that take into account the varying requirements of vehicles within your fleet. It requires extra effort, but it’s a relatively small investment that may pay big dividends.
