Spring maintenance

[Bulldog]

Does anyone use something other than the pricy Kubota UDT hydraulic fluid? I changed filters this year and will do a full hydraulic system change next year. It takes 16 gallons on a M9000 so it isn't cheap using the Kubota oil. I cannot bring myself to use the common yellow jug/green top that is rated as hydraulic and transmission oil but would like to hear what others are doing.

Transmission is $15-20K to rebuild. I don't blame you for staying away from the yellow/green jugs.
I also understand the expense, I gave almost $2k for a drum of Amsoil hyd fluid first of the year.
