Hydraulic oil recommendation

[Mustang Guy]

One man's opinions and speculation. I didn't see the science anywhere, but he did say to read the labels.

I just Purchased an old NH LS180 and did a full service on it for my piece of mind. Hr meter at 2572. Oil filter had 2454 penciled on it. Maybe that was when it needed to be changed, maybe that was when it was changed, who knows. Runs great. Blew my bucket seals after 2 hrs of work, not great. Just changed them and was adding Rotella t6 10w30 to it to top off and ran out of oil here at 10:30 at night. I have 20 gal of Penzoil Platinum Ultra 10w30 gasoline oil stored for my Truck and wife's car and was about to dump it in the reservoir. Glad I decided to come here and do a little digging to see if that was ok first. Nobody says it can or can't. So, I'm just going to put diesel oil in it like the manual says. The lack of comments on this particular "solution" speaks volumes. LOL

To be honest I have not been able to unravel the conveludid tale of what New Holland actually wants in their machines. When we bought our used 2022 C332 from the dealer we were given an older 2019 publication of the Operations manual I remember it did have 10W-30 CK-4 oil listed for Hydraulic fluid. I then got a newer Operations manual February 2022 PN 91788716 and 10W-30 can not be found in the manual outside of engine oil selection due to temperature environment. The newer manual has 3 listings:
Premium Hydraulic Oil HV68 Multi-Grade AW (-15°C to 46°C)
Premium Hydraulic Oil HV46 Multi-Grade AW (-35°C to 38°C)
Engine Oil SAE 0W-40 CK-4 Full-Synthetic (-30°C to 46°C)
You will note the absence of 10W-30 CK-4 oil.
At the parts counter I asked for Hydraulic oil for our machine and was given 'CNH Hydraulic Transmission Oil Premium' this oil only says 'MAT Spec Approved'. When I asked are you sure this is approved for use in our machine the parts person said that the regional service manager told them that it was better than the above choices. He the regional manager did not say approved just better. My parts person was emphasizing the 'MAT Spec Approved', then the logic would be any MAT spec approved fluid could go anywhere engine and or hydraulics. I believe CNH needs to educate their dealerships on exactly what MAT approval means.
What I have not been able to obtain is any documentation to verify that 'CNH Hydraulic Transmission Oil Premium' is approved for use in our machine either from CNH corporate or the dealership.
We used to have a saying in the Nuclear industry that "if is not written down than it does not exist".
I called another dealership gave them my PIN and almost immediately told they use 10W-30 CK-4 engine oil. If we brought the machine in that is what they would use. When I pressed the person on why they would not use the HV68 or 0W-40 the person stated that is what we use.
So we will be returning the 15 gallons of transmission oil and buying 15 gallons of the HV68. The 0W-40 FS is too costly.
CNH Rodchester does have a web page

New Holland Fluids Lookup

This is a guide to lookup New Holland fluids used on all machinery. You can also use this guide to lookup fluids for other brands as well, such as John Deere, Case IH, Kubota, etc. This resource serves as a supplement to our original fluids and filter guide.

www.newhollandrochester.com

that is somewhat convenient for determining what types of fluids you need.
For those of you who noted that the only difference between the 10W-30 and 0W-40 oil would be temperature operability congratulations but why the move to Full Synthetic. There has to be a reason let us know why.

Thanks all for the opinions.

Thanks all for the opinions.

Reading through this forum, I still have the two questions I posted on a separate thread. Where do I drain the hydraulic fluid on my NH 230 and are 10-30 motor oil and 10-30 hydraulic fluid compatible?

in most cases yes, just try to keep the mixing amount as little as you can by draining as best as you can. which is a good idea anyway to get as much of the old oil out as possible.

Sorry for interruption haven't been able to reply lately
Checking to see if administration got it worked out

as for if the two fluids are compatible or not, can be a gamble! IMO
as there is no honest way to know for certain , due to many brands use different mixtures, and chemical ingredients to make there oils, thats why there are different brands and some work better in certain conditions or just overall from each other.
and as such, it could be possible to have some thing in one fluid not be happy mixed into another.
pretty much every maker I know of, doesn't endorse mixing fluids/brands or types of fluids!
there are reasons there are different types of fluids
now the real question might be will mixing them, cause any issues ?
well that's where the guessing comes in
could they cause an issue, YES can they work fine together, YES
and I am NOT saying they will cause an issue, just saying it can happen!
chemicals can again have issues being mixed, as well as seals can also have issues changing fluid types, (an example is, SOME, have had leaks happen from just switching from dino oil to full syn oils, causing leaks /getting past seals and gaskets(mostly on older machines from what I have seen)
SO, I think most folks will always try there best to use correct fluid and use all of one type of fluid when doing any , fluid changes

there are again reasons why the OEM designers/engineers cal;l for "X" type of fluid, and thats what we should IMO!~

going against that can always have side effects and risks, be them good or bad! thus the gamble!

I now use Premium Hydraulic Oil HV68 Multi-Grade AW.

 

[Topper1]

It all becomes a mute point after we rent a post auger, tree spade, grapple, mower, snow blower and combine 280 different oil types from all the previous renters.

 

[Skaal LLC]

You are correct. If anyone has documentation of what the adverse effects actually are I myself would appreciate reading it. Lack of documentation implies opinion not fact.

 

[Topper1]

My annual hydraulic maintenance simply attempts to keep the fluid skewed to my standard hydraulic fluid type.
Read up on your motor & pump manufacturer recommended fluids. Whether it's rexroth, danfoss, saurer. For all my equipment, the approved fluids are broad ranging from standard engine oils to full hydraulic fluids and everything in between, which will normally blend without issue.
HOWEVER.. specialty blended ($$$) fluids can be somewhat testy in similar circumstances.
When in doubt, use a standard pump & motor approved fluid.
All my equipment (case, cat, asv, john deere) has been changed to a standard engine oil in the hydraulics, so all of my attachments can be swapped without worry potential issues with incompatible fluids.
Just my 2 cents. Right or wrong, I've had decades of trouble free service without a pump or drive motor failure.

TY Topper I agree with you. When oil manufacturers make statements implying possible implications from mixing oil types, without providing documentation, then in my opinion they are engaging in marketing not science. This holds true for manufacturers in many ways as well.
