Amsoil zero turn lube

Is the Amsoil Zero Turn Hydrostatic Transmission Fluid actually better than the manufacturer recommended 20W-50 motor oil or is it just re-labeled Amsoil synthetic 20W-50 motor oil?

I think about 25 years ago they recommended Mobil 1 15w50 but then changed that recommendation to their own labeled hydro fluid. If I remember correctly the formulation changed with the Mobil 1 and Exmark wasn't comfortable with the new stuff. I've used the Amsoil fluid before and couldn't tell you the difference or notice the difference between any of the hydro fluids.

I am using the Amsoil tractor Hydraulic fluid in my Tuff Tork K66. It is not motor oil. It works good in my Husqavarna. I'm sure it is not motor oil.

No not relabeled motor oil.

It is better, lasts longer and shouldn't shear as much so better protection for longer, plus plenty of antioxidants that aren't in engine oils. I've had the same fill in my abused Gravely ZT for 4 years now.
