If the oil were still good, why wouldn't you save the money and just leave it in the tractor?
If it's bad enough you don't trust it in the tractor, why would you trust it in a brand new splitter?
My thought behind the idea is:
Because it's not a 50k$+ tractor that has numerous hydraulic motors, valves, cylinders, etc...(that are PITA to get aces to and work on too) and it's not used for hours on end day after day like a tractor is.
It's a wood splitter, it has a pump 1 cylinder and 1 valve and will be used MUCH less. (Additionally these are all <$500 items that can be swapped in minutes.)
The "break in" on new fluid = dumping it in xHours anyway, so I thought why not use the 'used' (yet filtered) Super UDT I already will have excess off.
When the break-in is done and the hydro fluid is even more dirty (small particles as again, it has a filter) I can toss it and replace it with fluid that will likely last 10+ years.
It was just a thought I had to save couple hundred bucks on fluid
After all the log splitter will need around 15G in it so 30G after first flush is a hefty bill, but again it should be fine for 10+ years after the first 'clean' fill
