Gearbox Oil for Lathe?

[CalgaryPT]

It's been years since I did a thorough cleaning on my lathe. Also years since I changed the gearbox oil.

Mine is a Craftex (Busy Bee) CT089, 13 x 24.

What are you guys using for oil?

Non-detergent machine oil - aka hydraulic oil. Has all the appropriate anti-corrosion additives as near as I could tell when I researched it a year or two ago. It is exactly what is specified for most lathe type machines. There are a few specific specified oils, but ordinary (cheap) hydraulic oil seems to meet or exceed all the specs I found. Certainly good enough for a hobby machine that does not see 40-100 hours of hard use per week (more like a maximum of 2-3 hours of easy use).

What I ended up using. There were other posted discussions related to gear oil, terminologies, things to watch out for etc. you might have to do some keyword searching

I am using the 30W from Princess auto for compressors in my lathe. Seems to be match specs for the lathe and other shop tool sumps
