Manufacturer should not matter. AW-46 is an industry standard. The viscosity is listed in a couple of ways. There is "cSt" which stands for centistokes which is measured at 40 degrees Celsius (104 F) That's what the 46 means. That transfers to a viscosity listing of 100. The "AW " stands for "Anti Wear". It has excellent anti-foaming properties, that's one of the reasons I chose it for the shocks. It has a flash point is 227 degrees Celsius, which is 441 degrees Fahrenheit. I called it hydraulic oil because that is what I have seen it primarily used for. But I also have used it for headstock gear box oil in some rather large lathes.
