Extending oil drain intervals is a common area of interest for maintenance, reliability and lubrication technicians. The logic appears simple: if we drain and replace oil less frequently, it means fewer maintenance tasks and less oil consumed over time, lowering overall labor and lubrication costs. But problems begin to creep in if oil is not changed frequently enough.
The solution is to strike the proper balance. Some may err on the side of caution and decide that it would be better to drain and refill too often than not often enough, but this approach can lead to many unnecessary costs and risks.
