Hydraulic Oil

Carm,
Standard hydraulic fluids do adsorb water, as intended, to reduce free water and rusting in the system. There is no way that I would use fluid that is 10 years old. I would give under relatively controlled conditions of temperature, humidity and pressure --- maybe 3-5yrs. (depending on brand, reagents, seal, breakdown of the simple base oils and protective additives etc) in near perfect condition, while some would show signs of breakdown, atmospheric moisture contamination & settling between 24-36mo. In fact most manufacturers don't recommend using hydraulic fluid past 24 months. (all of these are unopened containers)
I would open it up and look for all signs of settling, water absorption etc just for kicks, but I wouldn't use it. I think you may be better off just disposing of it and buying new fluid IMHO. I hope this helps!

Well now that Ya`all may have convinced "Carm" that his oil is obsolete I would play the nice neighbor role and take that oil off his hands so he would not have to go to the trouble of disposing it. BUT from his house to My house is a couple of miles too far to make it worth while.cruisin

johnbron, I appreciate the neighborly offer, but.....no thanks. I also found some gear oil in gallon cans made specially for some abdulla hsjaddhfjskfh in Saudi Arabia. I dont know where it came from, but it sure is an odd find. Maybe Ill try to photo the stuff just for fun. Anyway, I guess I will smell the oil to see if it smells like it is bad. I can just use it to lubricate things. Maybe Ill dump it in the jet fuel I get from work to run in the diesel equipment. I dunno
Hi All, Lubricants can be a touchy line, As a rule, it should be good. If it is just a standard aw 32,46, or 68 I would have no problem in using it in a standard application. For newer applications where there are friction modifiers added to it and other additives the have a tendency to settle and seperate from the base oils. So, if it is just a reg aw oil, and you want to use it in an older tractor (pre 1970) I'd use it, the price on a bucket of Hyd oil can be quite dear, 29 to 45 dollars.
Hope this is of some help.

Andy, you are so true, hell Mom always protected him. :furious: :furious: :furious:
But I am with him on the oil, it can be used up to 1000 yrs just not for use in anything mechanical,how about an old oil lamp:furious: :furious: :spinsmile :spinsmile :idea: :idea: :idea:

It was no beg deal to order oil and other lubes when in the miltary and windup getting the spec'd fluid with a manugfacturing date of 10 or more years old. We even wound up with fluids that dated Viet Nam era during the early 90's. A check of the shelf life and most showed a shelf life date of unlimited as long as can or container was unopened.
My friends father-inlaw has a shed full of all kinds of motor oils most still packaged in the old cardboard foil lined quart cans requiring one of those hard to find pour spouts. Some of it is even multi-vis but the majority of it is straight weight. He uses it all the time. This fellow has more oil than some distributors do. Don't ask me how he acquired it all but he is well known as a pack rat and hunter of bargains so he has been collecting it all for most of his life. A lot of the oil is "Cities Service and Sinclair with the old flying winged Red Horse on them (now Citgo brand), so that shows you just how old this stuff is. Also has a few cartons of Arco branded oils / greases fluids .(Atlantic Richfield)
I certainly would not be afraid to use it, and if it appears to be clean and the container was still sealed it should be serviceable.

Chipmaker, we did the same thing too with the POL products on the flight line when I was still on active duty but our POL handlers would open test containers of the products and have the oil analysis lab evaluate them first and then use them if they met specs. Not sure I would pour something like that in my 4410's ehydro untested which is about a $2,500 transmission although if in a bind and no other resources, I would probably use it and keep a VERY close eye on it.
