Abstract
A method, comprising propelling a vehicle with an engine and a motor starting the engine if energy stored in an energy storage device is greater than an upper threshold level when a contaminant amount in the engine oil is greater than a threshold amount. In this way, it is possible to harmonize fuel degradation along with oil degradation, while still providing efficient vehicle and engine operation.
