Take the Guesswork Out of Oil Drain Intervals and Lower TCO
Karin Haumann, OEM Technical Manager, Shell Global Solutions
With total cost of operation top of mind for today’s fleets, every maintenance decision matters. Oil changes are no exception. Changing oil too early adds unnecessary cost and downtime. Wait too long and you risk engine wear and reduced performance. The sweet spot is not a fixed number. It is driven by how your trucks actually operate.
That is where an oil analysis program comes in.
Engine oil does more than lubricate; it also tells a story about engine health. By analyzing used oil, fleets can move beyond one size fits all drain intervals and instead base decisions on real world conditions. Factors like load, idle time, climate, air quality and maintenance practices all influence how long oil can perform effectively. Oil analysis captures those variables and turns them into actionable data.
With the right program in place, fleets can safely extend oil drain intervals where appropriate, reduce unnecessary service events and align oil changes with other scheduled maintenance. The result is less downtime and better asset utilization.
Oil analysis also provides early insight into potential issues. By tracking indicators such as oxidation, viscosity, additive depletion and contaminants like fuel or soot, fleets can spot signs of wear before they become costly problems. Over time, this data builds a clear picture of engine health across the fleet.
Programs can be scaled to fit any operation. Smaller fleets may choose to sample every truck, while larger fleets can test representative units operating under similar conditions to establish optimized intervals across groups. In both cases, the goal is the same: to maximize oil life without compromising protection.
Working with Shell and oil analysis through Shell LubeAnalyst can help streamline the process. From identifying the right oil and sampling strategy to interpreting results, a tailored approach ensures the program delivers meaningful value from day one.
At the end of the day, oil analysis replaces guesswork with data. That means fewer unnecessary oil changes, improved engine reliability and a measurable impact on total cost of operation.
