Being bored and looking for something interesting to read, I got on a forum discussing all brands/types of lawnmowers. We've owned Grasshopper front mount deck for years and have actually never had to service the hydraulic steering motors. They are pretty much bullet proof. Hst oil replaced every 1000 hrs. so I've never actually purchased any amount of the required oil.
On this forum there is the typical owner astonished by the price of the oil and wants a less expensive substitute. The discussion begins, lots of opinions!
I just checked online and a 2 gal container of the factory Fluid Cool Temp Hydro oil is $143.45 at the dealer without price shopping.
There are three different hydros used over the years, the latest is the G2. Older ones used 3 gallons, the next version used 7 quarts, and the latest use 2 quarts. On the latest version the owner's manual says change at 1000 hours. The Gemini hydro guru suggest do not change the oil, but folks want a number so they say 1000hrs.
Now, this conversation is very much like one on OTT about Kubota's SuperUDT2 and it's cost. Some refuse to think it's just overpriced local tractor parts store products. So a poster comes on and has some facts. It's a joy to read.
" I know GH recommends their hydro oil "only". Has anyone used say 5w-30 synthetic motor oil for an extended period? Or should I stay with GH's $$$$ oil?
If so, where is cheapest place to buy the GH oil? My local dealer wants $18.+ per quart.....
Here's some info I got from my neighbor that used to sell all of GH's oil to them (their factory is about 45 minutes from us):
A little history about oils with Moridge Mfg (Grasshopper Lawn Mower) in McPherson. When I was the Mobil Oil rep for the area, we supplied this plant with all of their hydraulic oil. It was Mobil 1 15W-50. I went to work for XXXXXXX Oil and got a call to come in and talk with one of the R&D engineers. He brought in some failed hydraulic orbital motors from their test stands. He and Parker (Mfr of hyd pumps and motors) said that the failures were due to the lack of anti-wear in our Mobil 1. They were not happy. What had happened is the EPA mandated a change to the levels of sulfur and zinc allowed in engine oils to reduce emissions. So Mobil Oil changed the formulation of their Mobil 1 to meet the EPA mandates and didn’t tell us on the industrial side of the business. Because Grasshopper was using Mobil 1 in an industrial type application, it was overlooked by Mobil Oil to let Grasshopper know. Mobil Oil and XXXXX Oil lost the business. Mobil 1 was the initial fill hydraulic oil for 20-30 years. However, it is not recommended by me to use Mobil 1 any longer, because there is not enough anti-wear in the new EPA approved Mobil 1 oil to protect the orbital motors in your mower. All of the blogs you see on-line are going off of old history that Mobil 1 is the best product to use, but they are not getting the protection they need. Also, I would not use anything but a synthetic oil, even though it is more expensive. Synthetics will give better wear protection also. So what I recommend is a synthetic oil, loaded with anti-wear additives. This RP product is what I would use and what I recommend. It will give you all of the protection you will need in any temperature. http://www.royalpurple.com/wp-content/uploads/2019/01/RP-PDS-Max-Cycle-2019.pdf

I guess the point is, it's the little things that make the difference. Make sure the little things are in the oil.
And you say, what does this have to do with Kubota..... it has a Kubota engine!
