udt vs super udt

[Marcussen]

I have used UDT and SUDT in my tractor, there is no difference that I can detect.
I was told SUDT is multiweight 10W-30 and UDT is straight 30. SUDT would be better in a cold climate.

My dealer and everyone else I talked to only sells and heard of regular udt (or "Premium UDT" as it's labeled) not even the super. Is there a product number for sudt2 that I could go to my dealer and order cause they are really good at that.

Half the time they don't know things exist until I hear about it on these forums and walk in there asking for it. They say no such item exists and I give them a part number and they are amazed that it does exist.

When they get requests now that they haven't heard of they call me to search and see if it exists and has a part number, lol.

Yes, Canada only sells "Premium" udt. No doubt equivalent to SUDT. Again, in the US, Kubota has been using Ashland (Valvoline) where in Canada, who did they contract with? Petro Canada?

 

[Volfandt]

UDT = 20w hydraulic oil
SUDT = 10w20 hydraulic oil
SUDT2 = ? I've heard it's still 10w20 and is a synthetic blend but I haven't seen it in writing as of yet. The bottle does say that it has "synthetic performance" but it doesn't come right out and say it's synthetic or a blend.

SUDT2 is replacing SUDT so you can expect to see less and less of the SUDT.
(my local dealer carries UDT & SUDT2)

As been pointed out, SUDT (and perhaps SUDT2) has better numbers/ratings in high heat and low cold conditions which would presumably indicate it's a better all around hydraulic oil but, people have been using UDT for decades without issue or performance loss.
So it's basically six of this and a 1/2 dozen of the other

The above doesn't include an info on Canadian Kubota fluids or other manufacturers' hydraulic oils

clear as mud?

That's a good question, I will have to see if it says who they contract with on the jug.

Even if the jug doesn't say, the safe handling paperwork always discloses the actual manufacturer.

I've heard that the newer little hydro tractors (like the BXs) are sensitive to that sort of thing. Old klunkers like my L4200GST don't care much. I went from what I think was Super UDT (when I bought it), to a UDT/SUDT mix, to a 100% generic UDT-equiv. from Sams ($7/gal). Everything works exactly the same, as far as I can tell. I do get a slight shifting lag when it is below freezing, but the additional lag goes away after a few minutes.

Jay, with that lag, how much additional wear to you feel you might be getting out of the hydraulic system??????

I did state in my earlier post of the differences between super and super 2 and for us here in NY the UDT to Super which is superior in the cold over UDT

Actually we are on our second BX and have used everything in them including UDT, SUDT, Sinclair, Ambra and Case and we couldn't tell any difference in any of them and we use our machines pretty hard.

The part numbers for SUDT2 is on the Kubota website here.

Kubota Tractor Corporation - Parts | Kubota Lubricants

Very simple, go to Kubota dealers parts department and order 70000-40205.

They will call you when it comes in.
