Looking for suggestions on alternatives to Cat HYDO 10 for hydraulic/hydrostatic oil in a 953b. What's everyone using?

Rando HDZ 32 is what I run. Some systems spec an ISO 46, but it's more cold than hot here. Up north at work, Rando HDZ 15 and a few use 22

Our local fuel supplier sells a 10w mobil that their guys call cat hydraulic oil. I think Mobil makes stuff for cat but it isn’t much cheaper than cat.
I used Schaeffer’s for a lot of stuff.

That's got to be some bottom quality oil for that price!

Wasn’t aware you could buy anything oil in 5 gallon pails, under 60 to 80 bucks!
