I recently brought home a Brown & Sharp Microamster 618 that has a hydraulic table. I was told the machine was drained of fluids before it was shipped, and according to the manual it takes 15 galons of high lubricity hydraulic lubricate and way oil. Having a viscosity of 150 S.S.U at 100ºf.
The spec sheet for Mobil Vactra Oil states that 1&2 are suitable for hydraulic systems in small machines.

I think I want #1 oil because according to this viscosity chart, 150 SUS (Same as SSU?) is equivalent to ISO VG 32, which is what No 1 is.
This makes sense to me but I would not mind someone correcting me if my logic is wrong.
