Abstract
A method (200) and apparatus 10-2 for carrying out the method of mitigating fuel in oil in an internal combustion engine of a hybrid electric vehicle, the method comprising: detecting a first engine start of a drive cycle when the vehicle speed is greater than zero (210); detecting a temperature of engine oil in the engine at the first engine start of the drive cycle (220); determining if the temperature of the engine oil is below an engine oil temperature threshold (230); when the temperature of the engine oil is determined to be below the engine oil temperature threshold, inhibiting an engine stop for a first predetermined time period unless the vehicle speed reaches zero (240).
