My machine is calling for either 10w30 or 10w40 diesel rated engine oil in the hydraulic system (older machine, calls for whatever is being used in the engine)
It currently has some type of regular old hydraulic fluid in it and seems to be working just fine.
For topping it off and changes though is it okay to use AW 68? It's available locally, a decent price, and it looks like at 100* celsius that both SAE 30 and ISO 68 have near identical flow characteristics.
