Abstract
A method and apparatus for mitigating fuel in oil in an internal combustion engine of a hybrid electric vehicle includes detecting a temperature of engine oil in the engine, determining when the temperature of the engine oil is below an engine oil temperature threshold, and when the temperature of the engine oil is determined to be below the engine oil temperature threshold, inhibiting an engine stop unless the vehicle speed is below a first threshold vehicle speed or braking of the vehicle is effected at a vehicle speed below a second threshold vehicle speed.
