I changed my splitter hydraulic fluid, and now have a bucket of waste fluid and some motor oil. I know I seen some guys use used motor oil as bar and chain oil, but how about used, decently clean hydro oil as bar and chain oil. I try to be super cheap, so I would hate to just drop it off somewhere to be recycled.
Zero tackifiers. It would fling right off the tip and provide little lube back where you do most of your cutting. I used a non specific oil once and pretty much killed a 36” bar.
I certainly admire not wanting to waste things, I am the same way. From all the reading I have done, real bar chain oil is the only way to go; it's not that expensive to protect a bar and chain. I bought several gallons of bar oil when it went on sale Tractor Supply.
I have seen saws that had used oil from cars and such. I does eventually cause premature wear on the oil pump.
No go. Hydro isn’t really a surface friction type lube oil. As mentioned bar will fail fast. Put some in a soap or ketchup bottle and use it as fire starter. Pretty high volatility as far as oil goes . Not like gas ,,, but a little gets things going good.
my plan for all my waste oil (motor/hydraulic)... https://www.youtube.com/results?search_query=waste+oil+burner+ got the tank already. Just gotta find some time to build it.
