Hmmm, I think it is UTF. Low BTU value.I don't know what kind of hydraulic fluid is .It came out of my tractor transmission on its first fifty change.
I ve been burning waste oil and woking on them for about 10 years and in that time I have seen burners not fire at all on hydro oil expecially virgin oil.
BTW, did I mention they make fire resistant hydraulic fluid out of PE's.
