    It is high but in concert with kubota to see if it reduces bubbles.

    I'm waiting for my next change to try something. We only have Premium UDT here in Canada and I noticed that after I did my first oil change on my B2620 the hydro whine got louder than when it had the factory fill in it.
    So I bought a pail of Super UDT the last time I was in the States. Curious to see if I notice any difference.

    My L5740 HST whine was noticeable when it was new, but decreased with use.

    Another member checked his on the same kind of machine and it was identical. This could be the norm for fluids, I would like to see more samples from others to know.

    the oil was extracted from the fill hole with a syrenge after warm up. It clears up pretty quickly. Another member here checked his m59 the same way with identicle reults. Different fluid tho.

    Was there ever a resolution to this? Sounds like a suction side [air] leak.
