Thanks for watching. Hope the data was helpful. Used hydraulic fluid test results are in from the lab, so I'll be posting a video on that soon.

That matches up with what was shown in my freezer test. Question is, how did Traveller get in your tractor in the first place? It definitely didn't come that way from the factory.

If you want cheaper oil I have had good luck with Walmart supertech tractor hydraulic oil.

Thanks for the recommendations. Kendall looks like it might be difficult to find around here, but the others should be doable. Aiming for late winter or early spring depending on channel income to pay for it all.

That's what I was originally thinking, but check out the round 2 video linked in the description. Even Amsoil hydraulic fluid had double the phosphorus and zinc compared to UDT2. I have a hard time believing that Kubota base oils are better than Amsoil which is a full synthetic.

Whether each company actually classifies their blends using their company classification scale, not sure how you would know that unless someone at Kubota told you. It does seem to make sense though that the blends would be either proprietary or contractually specific to Kubota. The research I've seen showed that Valvoline makes Kubota's blend for UDT2. How did you find out that Mystic JT-5 is close to UDT2? Is there a site out there with test results?

@@Redneck_Ed Theres a thread on Orange Tractor that went over these oils. The UDT oil information I got via the Dealer from a tech who took several classes from Kubota.

@@acdii I appreciate the follow-up and I do not mean this to be taken the wrong way, but this video is about trying to move the topic from subjective into the objective. There are gobs of threads out there where people generally say things like: I have used blank brand for 15 years and have never had a problem or I spoke to the tech and he told me blank. Tech's don't represent the manufacturer, so their info needs to be viewed in that context. For example, the tech at my Massey dealership told me to use 15W-40 engine oil in spite of the 10W-30 recommendation in the manual. Mystic's own product info sheet does not claim UDT2 compatibility (they only claim UDT). Mystic specs do not look terrible, but at least one category is way off. Mystic JT5's viscosity index of 145 respectable but nowhere near 199 of UDT2. THF base oils (including Kubota UDT2) are not proprietary as they are posted openly on their safety data sheet: 58% heavy paraffinic distillate, 1.47% polymer, etc. Mystic is >90% heavy paraffinic and no mention of polymers or things like alkyl imidazoline that's in UDT2. I don't have the insight to know good vs bad for the base composition of these products, but apples to apples comparisons are easy to do by looking at the SDSs and then add in the missing link of the lab tests showing additives packages, viscosity, and TAN. Once you have that info, then you're making an informed decision to go with the manufacturer's recommendation or go on your own with another brand. Without it, people are just buying the cheaper product and rolling the dice.

@@Redneck_Ed Well, yeah, thats why I said would be good to have the Mystic JT5 tested too since it was mentioned to be compatible, but is it? I know for fact that Kubota does do oil analysis for warranty work on their HST. The only time they really bust a warranty claim is if they find 303 being used instead of UDT or UDT2. John Deere fluid in the older Kubota HST works, but does whine a bit more than UDT. I would not use it in my L4060 though but works perfectly fine for the last 20 years since that is what it came with. For me, the biggest question is what works in a pinch when UDT2 cannot be located, like what happened to me, I was swapping out filters and it dumped out a lot more oil than I had on hand and with the dealers out of stock, needed replacement fluid. So far no issues running JT5, even in the cold.

@@acdiiGood points. I do wonder though about JT5 since the SDS shows the base oil composition as being drastically different from UDT2. Do you think there is risk in the long term in the area of internal wear and tear on parts and the hydraulic pump? As I stated in the video, I'm willing to test more samples and pay for it, but I can't pay for the oil too. I'll need help with that. I'm already in the hole about $200 on KZfaq expenses vs my channel's income this year. If I can get above water by spring '24, maybe I'll buy some more samples and run them through the tests.

I wouldn't mix in the transmission, but mixing in the front axle doesn't seem like a big deal. A lot of guys don't even run Permatran in the front, they run gear oil instead which apparently was what the older GC manuals spec'd for the front axle. People have said that Massey changed to Permatran for simplicity.

@@Redneck_Ed Thanks!

Sorry, I can't say. The dealer in Howard County, Mullinix, also sells an alternate brand. The guy told me it was from a distributor in Baltimore, but I never asked him for the name. Only thing I can suggest is to call Mullinix and see if Mag1 is also the brand they stock and maybe make a confidence decision based on that. Or depending how close you are to PA, there are Massey Agriteer dealers just across the line in PA that sell Permatran. If I were going to go with an alternate brand, I think I'd use Mobile One from Tractor Supply based on the testing done in this video.

@@Redneck_Ed Thanks Ed , that’s a good path to travel and thanks for all your in depth videos .

I knew that comment was coming, lol. Had to draw the line somewhere. Rotella was a lot more expensive than Traveller and Delvac and Rotella also seems to have more of a track record which translates to less uncertainty about quality/contents of the fluid. If you're interested in seeing Rotella tested, the offer is out there. All you need is a new container of Rotella and sacrifice 3 oz of new fluid for the Blackstone sample.

@Redneck_Ed another great video. When I bought the shell last time it was 54.00. The best price I see now is 100.

yes up here in canada shell has gone nuts in their pricing, i used it exclusively for years and had no problems. Now i look for good names and cheaper oil.@@chrishunt5291

I'd like to think that many of the posts are people overwhelmed by the wall of fluids at the store...ISO46, ISO32, THF, etc. The rest are people who want to hear that someone else has used a particular brand fluid in the same model tractor (i.e., they don't want to be the first) or they want to hear if someone had a problem with a particular brand fluid.

@Redneck_Ed I respectably disagree Ed. Still see the same people saying ,I'll stick with agco products, whether it's for warranty or they really believe they make the products. 🤔

​@@chrishunt5291 The testing I've done so far supports all of the above as valid decisions unless someone switches from a Denso to the lower tiered junk Fram PH model filter. For someone who has to drive a long way for Permatran, there are clearly valid alternatives. I'd like to see a dealer deny a warranty claim for someone who uses Delvac instead of Permatran. The products appear to be nearly identical. On the other hand, if you have a BX then the cold weather viscosity and low starting TAN might be a good reasons to stick with UDT2. Next up for me is the pesky hydraulic filter. I know there is at least 1 Wix alternative, but I need to cut the Denso open first to see what it's like inside. That will be a future video!

@@Redneck_Ed you do an awesome job. I do need to know the hydraulic filter info.

My order of TRIAX Agra UTTO Supreme Universal Full Synthetic Tractor Hydraulic Transmission Fluid arrived yesterday. By coincidence, I ran across your video. I planned on sending a sample to Blackstone. I use Blackstone Labs quite often in the past for similar tests involving engine oils, both virgin and used samples. Where do I find your email address?
