An oil system (10) configured to supply oil to a transmission (4) and an electrical machine (3) of a vehicle powertrain is provided. The oil system (10) comprises a mechanical pump (11) configured to transfer oil to a first supply conduit (16) of the oil system (10). The oil system (10) further comprises a second supply conduit (18) configured to supply oil to the transmission (4), and a third supply conduit (20) configured to supply oil to the electrical machine (3). The second and third supply conduits (18, 20) are fluidly connected to the first supply conduit (16). The oil system (10) further comprises a controllable valve (24) configured to control an amount of oil supplied to the electrical machine (3) via the third supply conduit (20) through control of oil pressure distribution between the second supply conduit (18) and the third supply conduit (20). A control device and a method for controlling oil supplied to the electrical machine are also provided.
