What Type Hydraulic Fluid for Mini-Ex?

[davey4000]

The manual for my Kubota KX91-2 specifies ISO 46 (in my temperature range). Kubota oil at the dealer is double the price of ISO 46 at Tractor Supply. Is the TSC oil the same? In other words is ISO 46 essentially the same in all brands or does that simply mean the viscosity is the same, but perhaps not equal based on other required additives? Should I purchase the "official" Kubota oil?

ISO 46 is the International Standard. If the label has the "AW" prefix or suffix it contains the Anti-Wear additive package and is indicated for all hydraulic systems requiring ISO 46 oil.

However, if your tractor uses UTF use that.

Personally, I use ISO AW 32/46/68 multi-grade hydraulic oil.
