Here is some better organized comparative data. I think the cold performance winner is clear. Pefromane/cost wise J20D is probably the winner. There are other choices out there if you look but avialability is spotty. Chevron Synthetic THF is one example. While billed as a JDM J20D fluid it is actually closer to JIC/CNH Ultraction SSL (CNHI MAT 3553) and priced roughly the same as both Ultraction SSL and Amsoil ATH - twice the cost of SUDT2 and HyGard LVSUDT2 is not available in Canada, only the Canadian version of UDT ("Premium UDT"). Which is different than the US version. MSDS with some specs here: https://www.orangetractortalks.com/forums/attachments/premium-udt-e-2012-pdf.22834/ No VI or -40°C kinematic viscosity listed though.
Interestingly, while the viscosity index of the Amsoil is higher than SUDT2, the pour point is lower. Comparable to Duratran XL at -50°C. But the lowest pour point of all is the (conventional) Canadian "Premium" UDT at -57°C. Kinematic Viscosity @ 100°C is the same as Deere Hyguard at 7.1 centistokes.
In a real twist of irony, Kubota brags that Premium UDT meets J20D specs. <lol> It is also reassuring to know that Premium UDT performance is similar to Premium UDT.
Here is the unexpurged text from the Canadian Premium UDT labels:
Front label:
"Premium UDT Hydraulic/Transmission Fluid".
"Built to last".
"For tractor transmission and hydraulic systems. Compatible with wet disk brakes".
Repeated in French.
Part number 72000-03406.
