An oil supply system includes a first oil receptacle collecting oil from a transmission and a second oil receptacle collecting oil from the rest of a drive system using gravity. Oil supply pump(s) supply oil from the oil receptacle(s) to the different consumers. A vacuum pump generates a negative pressure in the first oil receptacle and in the transmission casing connected to the first oil receptacle. A gas check valve prevents gas from flowing between the oil receptacles when a pressure differential is applied to the oil receptacles by the vacuum pump. An oil check valve prevents oil from flowing between the oil receptacles when the pressure differential is applied. An oil regulating valve may control the oil flow between the first and second oil receptacles. The oil supply system provides a simpler configuration without scavenging pump(s).
