What’s the deal with aw32/46/68 Hydraulic fluid

Completely different formulations and properties

anti-foaming agents
anti-wear additives
anti-corrosion additives

etc. etc. etc.
 
That wasn't much help.


Why carry different weights if one can cover all ?

Is there any downside to using this weight ?

What Brand are you referring to? Do you have a link?
 
its just the orellys brand i wanted to get one hyd fluid to use in dump trailer dump trucks other small systems
 
as a hydraulics engineer, I would steer you away from multi-grade oils...pumps/motors/valves are very tough on VI's
Pick the proper viscosity for the temperature range and equipment you are using...happy to help if you can answer some questions.
