Hydraulic fluid choice

[Ditchwitch650]

I need to drain my hydraulic reservoir to fix a puncture leak. My mini loader (ditch witch sk650) manual and dealer says to use any universal THF. I bought some OReily 303, but research is telling me this is for older tractors and a cheaper grade. I'm thinking maybe AW32 is the best choice? Am I really going to be able to tell a difference besides the amount of hours before I"m supposed to change it? My tractor is a 2007 with only 180 hrs so I want to put the best universal tractor fluid in it. Thanks for bearing with me, I'm new to hydraulics and tractors and just want to make sure I make the best choice

trans/hydraulic fluid typically has a better additive package and maybe even higher quality base oil than basic aw hydraulic oil (why its cheaper). if unsure I always err on the side of caution and go for THF. So plain AW32 hyd oil would be a step down from the 303 THF.
