    :confused: What do you guys use for tranny oil? How often do you change the tranny oil/filter?

    We are guilty of not changing the hydrostatic oil often enough (according to the manual). When we did, we used "John Deere" hydrostatic (transaxle) oil.

    Our ride-on owners manual suggests 20W-50 oil. Is this the same as most other manufacturer's recommendations regarding transaxle/hydrostatic fluids?

    If so, I plan to use "full-synthetic 20W-50 motor oil" from now on. Is there a difference between 20W-50 motor oil and hydraulic fluid? Are synthetic oils bad for transaxles?

    rscvp, thanks

    p.s. Mowers too

    I don't think there is much difference between motor oil and hyd oil.

    Mostly it would be additives that they put in the oils because of the uses.

    Oil would be a hyd oil in a motor to keep engine parts from touching each other like / hyd lifters / hyd timing chain or belt tension.

    I think hydraulic fluid doesnt compress like motor oil and likely has an effect on performance of hydraulics

    If it helps mower mfg's (scag/hustler/etc) call for 20/50 motor oil also. I just use napa oil and change it when it smells burnt or yearly.

    My guess is it helps lube the wheel motors and compression isn't the main issue. Plows/skidsteers/etc use hydro fluid. Basically stuff with lift,ram cylinders so compression is the main thing they are stopping.

    Motor oil doen't compress or it wouldn't work on things like hyd lifters in your engine. Oil pressure is what keeps your rods from knocking in your engine.
