10W-30 HYD replacement or substitute

[arlen4720]

I read the WACKER spec again yesterday. Anti-Wear Hydraulic Fluid 10W-30 in the hydraulic system. API rated SAE 10W-30 in the Briggs 16hp, and SAE 10W-30 in the exciter box.

Many of the popular hydraulic/transmission fluids are 10W-30 fluids.

XSKIER--I know you have some JD hygard around. JD says that works in systems specified to take a 10w-30 AW hydraulic fluid.

As I understand it engine oil and hydraulic fluids are same as to body (10w30 and such) the difference is in additives, engine oils have different additives than hydraulic fluids (oil) difference is wear factors and anti corrosion and what ever....

Found the specs for Hydrau. I have Hy-Gard low viscosity here, but that is like a 10 weight oil. My local dealer did not have any Hydrau in stock. I have decided that AW 68 should work ok for this application. I have the AW 32 Lube King in my Yale lift truck, and get good performance out of it. View attachment FAQ_Hydrau_HydrauXR.pdf
