Does anyone use aw32

I think most people use hydraulic oil in their hydraulic systems already.

I don’t think anyone uses engine oil in a hydraulic system.

Engine oil is used as a hydraulic oil in many of the older pieces of large construction equipment and is the spec in PowerTracs.

And many modern machines call for it. New Holland skid steers are one example. They have spec'ed 10w-30 since the LX series came out in the 1990's.

@woodlandfarms Thanks for asking! It would be great to know if there are Power-Trac owners who have used it and what their experience is.
I looked previously in the Power-Trac forum, and I couldn't find any one who did.
All the best,
Peter

Nope. Still using the same engine oil in the hydraulic system that it came with 20 years ago, minus a fresh quart of Mobil1 at every 50 hour filter change. Many folks have discussed changing from engine oil to hydraulic oil over the years, but I cannot recall any that actually made the switch.

Im not an oil engineer......but I dont think there is anything in a powertracs hydraulic system that is any different than other hydraulic systems that use hydraulic oil. Pump, cylinders, valves, etc. Does engine oil work....yup. Does it need the extra additives that are in engine oil....probably not. Are you likely to see any oil related failures with either if you preform service at specified intervals...not likely. And Cost is likely very similar....about $10-$15 a gallon. My guess is some of these companies using ONE type of oil has little to do with whats "better" and more to do with stocking less oils and bulk costs. And engine oil in hydraulics probably works out better than hydraulic oil in the engines....lol.
I have been running generic Napa Hytrans Ultra in my machines for a few years now. I do not notice any difference in operation or performance.
As I think about it while typing this, I don't think I have replaced a wheel motor on my 425 since I switched it over. I used to blow the seals on the right front wheel motor at least once a year. It is very likely this is due more to the fact I flushed the hydraulic system when I replaced the hydraulic pump (and oil) more than the type of oil used. From my experience, I suspect keeping the oil clean is more important they the type used.

@scotts562 Thanks for the update.
Any idea why the front right would keep blowing seals? Just curious.
All the best,

From what I have seen and from conversations with Power Trac, the front right wheel motor is the "first" (for lack of a better term) in the hydraulic circuit so it takes the most abuse in a pressure spike. Back right is "second", back left is "third" and front right is "fourth".
On my machine the front right (i.e."fourth") wheel motor is the only factory original one left on the machine. "Third" has been replaced once, "second" repaired/replaced two or three times, "first" has been repaired/replaced multiple times.

That's interesting...I was out doing a LOT of tilling today and noticed that the right front was the first one to spin if there was a loss of traction. That's probably related!

I'm also using the same 5-30 oil with the addition of Mobil1 at filter changing time. I have thought about a total hyd. oil change, just never got around to it. I guess with enough filter changes I don't have to worry about it.
On a somewhat related topic, I noticed some milky white fluid in my log splitter's hyd. oil...figured water. Changed out the oil and I still have it. I drained as much of the oil and used the mfg. recommended oil. Is another (or 2) fluid changes needed? Do I need to flush it somehow?

Sorry to hear about the milk in your log splitter. Never a great thing.
Yes, it might take a couple of changes if you didn't clean and dry out the sump. Some old timers that I know run some diesel through to get the water out. Definitely a YMMV thing.
To the extent that you can drain the hoses when you do the fluid change, every little bit helps, but changing the fluid twice may be easier if you don't have a super clean place to put all the hoses.
All the best,
Peter
