okay-you guys win-------I'll use udt-dealer said super udt not necessary in the South and he doesn't even carry it- they use it up North where it is colder as it's thinner- so i learned something today- he did say 90 % of the kubota problems that they see are because people don't change the fuel filter on a regular basis-[$13 ]-he said it should be changed each time the oil is changed or every 100 hours-so we'll do this also---------Have a great days all you guys and gals.hads good luck using tractor supply universal transmission fluid it so i guess i'll stay with that- we use it in about everything around here-big big diff in price from kubota super udt
