Has anyone tried NOCO's Torque TDH hydraulic oil in preferably a late model Deere? Specs look identical in their PDS to HyGard,just want to make sure.Price is $17 cheaper for a 5 gal. can. $51 vs. $68.
I changed to Chevron Hyd Fluid from JD HyGard in my older equipment. HyGard got to be way over priced and I could buy Chevron for about $350 a barrel less. Both have the same specs although it is a little darker than the JD.
Chevron "Synthetic All-Weather THF" meets JD J20C and J20D specs. Viscosity at 40*C/100*C is 44.7/9.5 cSt.
Chevron "THF W" meets J20D only. Viscosity at 40*C/100*C is 34.4/7.3 cSt.
If I remember right John Deere says you can use motor oil 10w-30, 10w-20. That seems weird to me, motor oil additive packages are very different than hydraulic oil packages. Amsoil makes a synthetic for JD, its probably really expensive though.
Have you looked at who is on the OEM sheet for your Deere?

I can't speak to Chevron, but I have a lot of experience with Mobil, Petro-Canada and CNH HyTran with no oil related issues.
I did look up 1000THF in particular. It is made with "ISO SYN" which is hydro-cracked group 2 base stock (group 2+). In general terms each group up provides improved thermal/oxidation stability and low temperature properties. Group 1 is the cheapest while group 4 is synthetic. Only very high end non-synthetic lube oils will use group 3. From what I can gather the main thing to watch with hydro-cracked base stock is that once the anti-oxidation additives are consumed they are more prone to sludge formation.
No matter which oil you choose, I would recommend you have a regular oil analysis program in place as cheap insurance. I don't know who is in your area, but most CAT dealers provide the lab service.

I use Chevron 1000THF in everything I own. I get it in bulk, Everything seems to work fine.
You can NOT use engine oil in the hydraulic system of a Deere.As you say,complete different packages.As stated already,Chevron makes HyGard.
