GR2100 front axle fluid

[wbillrad]

GR2100 manual is not clear on what fluid to use in the front axle. Have been using Amsoil 80-90 which seems to work fine but wonder if I should be using Super UDT?

80/90 gear oil is my choice.

The Operators Manual looks perfectly clear to me - UDT/SUDT.

they came with super udt. I always put super udt back in them since that's what the manual calls for. UDT would work as well and is less expensive.
