RE: Grease and Lubricating oil
One thing that can happen to grease especially the lighter grades is there will be an oil/base separation which will be enhanced with temperature swings. If this happens I would toss it while I've seen it partially mixed and used..
Having said that I would get with your lubrication supplier and see what the manufacturer's recommendations are. .

some products may however have a more limited timespan. an example is an open gear lubricant that contains a volatible component to ease application. other examples are metalworking fluid concentrates (soluble oil)that usually need to be stored indoors to prevent exposure to frost. there may still be other products that have a limited timespan - you better check with your supplier.
once the container has been opened a period of half a year is a safe measure (as long as you keep water and dirt out) and that period may again be smaller if the lubricant contains volatile components or are hygroscopic (eg brakefluid).
the oil/grease separation as mentioned (bleeding) does not render the grease unfit for further use, the oil separated from the grease can usually be taken into the grease structure again by flattening the surface in the container - preferably with a suitable spatula (not wood or metal). it is a good idea to keep the grease surface in the container as flat as possible to prevent excessive bleading with a follower plate.
