PTO clutch oil question

I have a JD 720D and I have to change the pto clutch oil. The operator's manual calls for 10wt oil. Going to Tractor Supply and auto parts stores, I can't find any straight 10 wt oil. Doing some research, I found that home depot sells a hydraulic oil that is ISO 32 which is the same as 10 wt SAE. Also walmart sells a mobil hydraulic oil that is 10 wt. My question is, can I use hydraulic oil like this in my pto clutch?
 
I usually just run JD HY-Guard oil in those clutches. It will not hurt clutch facings where the oil your talking about may delaminate clutch disk facings. By the way JD HY-Guard is a 10W oil. The JD HY-Guard is a much better quality oil than the straight 10W they had when your tractor was new. It has water inhibitors that the straight 10W would not have.
