The DHT splitter says to use AW 32 or 46 but SAE works for overall general options since it rarely gets much past freezing around here. Let me know what you think. I don't think this would be a true issue since it falls in the heavy side and temps here are mid way anyways.
10wt would be closer to the same viscosity as AW32 20wt is close in viscosity to AW46. The other things to watch for are foaming and temperature. Hydraulic oils have additives to address these issues more so than motor oils. Mike in Okla
What I have is both buckets. AW 32 light hydro fluid and then I have Super S Agri + fluid in SAE 20 My thoughts on this is I don't plan to split much during a freeze unless it's by hand. But I have the buckets because my splitter suction line failed, leaked all that fluid out. Nearly. So 4 gallons of the stuff has to be used.
