    I bought a used fischer elec/ hyd pak (older speedcast) and so far it works great. When I changed the fluid to a low temp $$$$ hyd fluid a few weeks ago I noticed a squealing sound when I drop or sometimes when I angle. It is pretty loud in all temps even though up here in Vt. we haven't seen 15 degrees for weeks. Anybody think it is just coincidence. Shoukd I be concerned about the noise? Should I go back to tranny fluid and see what happens? I would appreciate some advice.

    What you probably hear is some free play in the pump now that you have switched to a lighter fluid. You should be alright as long as everything else seems to function properly and with good pressure.

    You should never add alcohol to "plow fluid", it already had a de-icing agent added and to much alcohol can damage the o-rings.
