Abstract
An oil dilution inhibiting apparatus is configured to inhibit oil dilution caused by mixture of fuel into engine oil. The oil dilution inhibiting apparatus includes a control unit. The control unit is configured to estimate friction of an engine and determine that the oil dilution occurs when the friction of the engine is decreased to a value lower than or equal to a predetermined threshold value to perform control so that the engine is operated at a higher speed.
