Various disclosed embodiments include oil systems, electric motors, and vehicles. In an illustrative embodiment an electrical motor system includes an oil reservoir, a motor, and an oil delivery system. The oil reservoir is configured to hold oil therein. The oil delivery system includes a heat exchanger. The oil delivery system is configured to operate in a low-temperature mode, bypassing the heat exchanger, while the oil temperature is below a first predetermined temperature; operate in a high-temperature mode, directing oil traversing the oil delivery system through the heat exchanger while the oil temperature is above a second predetermined temperature; and operate in an intermediate-temperature mode, partially bypassing the heat exchanger while the oil temperature is between the first predetermined temperature and the second predetermined temperature.
