A lot of mowers have hydro gear transaxles and just spec regular 20w50 motor oil. What happens when you use the equivalent weight hydraulic fluid? Not sure which ISO number that would be.
PCMO will have better rust and water tolerance as well as sludge dispersion but lower EP or AW properties but in a low use/load environment both would be fine IMHO
