"Use machine oil, not a spray lube or other thin oil. Unless a hub has sealed bearings, also use grease, to form a seal at the bearings and help keep the oil in. "

The OEM Sturmey oil was
non-detergent machine oil which is what 30W lawn mower oil is.
In practice use restraint in oiling an AW w/ Phil, mower oil or whatever potion one chooses, a few drops when the hub sounds like it needs it are all that are required.
