AW32 vs. UTF?

[azelgin]

Ok, I have an old (1977) Ford 1000 with 770 loader with a seperate from transmission hydraulic system, that ended up with AW 32 fluid in it instead of UTF, or Ford compatable. Is there any reason this would be a problem? As far as I can recall, it has been in there for about three years and 300 hours. It blew a hose and AW 32 was what we had on hand for a refill. It seems to work as well, or better than it used to. The pump is quiet, it lifts as fast as it ever did and doesn't leak. Should I change it back to UTF? What's the worst that could happen, if I leave it alone?
Thanks for any ideas.

If the loader uses a seperate sump than the tractor.. then aw32 is fine.. though i persoanlly prefer to use UTF in most applications where plain hyd oil is used, when dealing with tractors.. etc..
