One of the things that opened my eyes to who refines oil was my honda snowblower.
I took the hydraulic drive apart and need to refill it. The honda oil was like 16 bucks a quart. My buddy who runs a snow removal business said, "do you think Honda makes oil?, no they just have their labe put on the bottle." He runs standard hydro oil in all his machines.
Honda says not to run anything except their oil. I filled her up with some hydro out of a 55 gallon drum that my buddy had and she ran for another 5 years before i sold that machine......
