Ancient yanmar wisdom? (hydraulic fluid choice help)

[agjones]

Just picked up an undocumented yanmar orphan made in the 90s. It's a wheeled excavator. Needs hydraulic fluid. It doesn't have a tracked sibling that I know of.

Any input on what yanmar would've specified for their excavators in the 90s?

My 1990 kubota mini ex also calls for 046.
