摘要：
In one exemplary embodiment, the state of engine oil degradation is monitored and determined using the size of viscosity hysteresis during heating-cooling cycles. In another exemplary embodiment, the state of engine oil degradation is monitored and determined using the sign of viscosity hysteresis during heating-cooling cycles. In yet another exemplary embodiment, the state of engine oil degradation is monitored and determined using relative viscosity changes hysteresis during heating-cooling cycles.
