The intended application makes this slightly OT but the group seems to have extensive lubricant knowledge (and purchasing in small quatities). Too late to ring the manufacturers and my "domestic"(2000W) log splitter needs the hydraulic oil topping up. My friendly local farmer has AW32 , 46 & 68 oils available foc to me. The product manual specifies ISO 20 oil in the change/top up section but then specifies SAE 20 in the technical data.45mins of web searching has informed me that: ISO 20 is the viscosity range of AW22 hydraulic oil ISO is at 40degC SAE is at 100 degC (?) A comparative viscosity classifications table shows SAE 20(crankcase) overlapping ISO VG (viscosity grades) 32,46 & 68
Do I wait until tomorrow or risk mixing in AW32 ? - the oil capacity is 2,4l and I doubt I need more than 1/3 litre. If AW22 is required any suggested sources in small (5l) quantities?
