An oil system for an aircraft propulsion system. The aircraft propulsion system comprises a motor configured to drive a propulsor via a reduction gearbox. The oil system comprises a first feed line configured to supply cooling oil to the reduction gearbox, a second feed line configured to supply cooling oil to a further oil cooled component, and an air-cooled oil cooler. The air-cooled oil cooler is provided upstream of the first feed line to provide cooled oil to the reduction gearbox; and the second feed line is configured to bypass the air-cooled oil cooler to cool the further oil cooled component.
