I bought some Redline manual transmission oil for one of my cars few years (~10) back but never ended up using it. I just stored it.

I am thinking of using it now. Question is is it a good idea to have use oil that old? Would the oil lave lost any of its properties. Or, can I give it a good shake and use it?


Thx.
