SUDT2 versus Universal Hydraulic Fluid

[stoyan79]

So is SUDT2 fully synthetic or synthetic blend?

40 gallons i just choked a little.
I thought the 17 gallons our tractors hold was expensive.

i have the SUDT2 in my M8540 its slightly better but in cold weather but around say <10 ｰF i still have to warm up for 10 minutes or i get pump whine and both the main shift and even the range select are extra sticky. At 600 hours I'll got to AMSOIL or install a heater into the side case drain. maybee I'll do both i hate pulling the drain plug. I also have a Fumoto valve to install.

Dave, if you switch to AMSOIL post a thread and discuss the noted differences.

Good question. I just read the jug and it doesn't claim either. So I'm guessing it's a blend. I think they'd brag about it on the jug if it was more than that. :confused3:

OK, so UDT and SUDT are dyno, and SUDT2 is a synthetic blend.
In this case, paying extra for 100% synthetic AMSOIL might be a good investment.

I would love to hear from anybody who has used both SUDT2 and AMSOIL.

Also, my tractor calls for SUDT2 in the front axle, can I substitute with the AMSOIL I will be using in the HST?

Howdy ovrszd,
I will definitely start a new thread when if and when I do this. I'm hoping that i will have my tractor paid for by the time i hit the 600 hour mark.

From what little I have read about SUDT2 it is 75% synthetic.

I use, and have always used John Deere Low-Visc Hy-Gard In all the tractors I have (had). Over 7K hrs. and not problem, I don't know who makes there oil but will bet JD keeps a tight rein on the spec's. Also, It cost less than SUDT2

We have had excellent success with just upgrading deere ag tractors from the hygaurd to the hytran from Case-IH. Kubota would be an upgrade over the Hytran. Your call. Deere's oil has not been outstanding when testing. Good, but not great.

Does anyone know what Kubota fills the grand L's with at the factory?

They all come through with the superUDT as they might go any where in the world.

Do you have a copy you can post of this JD oil test your refer to??

So I guess the sudt2 I have waiting at home will be an upgrade. That's nice to hear for what it cost.
