........................................................................................................There are several grades of AMSOIL Synthetic Hydraulic Fluid.
How did you decide which product to buy?
I am in Florida so winter weather need NOT be considered.
Only one is called " Tractor Hydraulic/Transmission Oil " It meets the LS API GL4 requirement and is recommended for the same Brands and Specs as the LS branded hydraulic fluid.
Here is a link: AMSOIL Synthetic Tractor Hydraulic/Transmission Oil SAE 5W-30
Here is a picture showing the Brand Specs on the LS branded hydraulic fluid container.
