It depends on the use and how old. If it's over 3 years old, I would expect the base/carrier oil has partly oxidized and the lightest fractions have evaporated.
Rotate it 90 degrees every day to try and get the pigment off the solid layer in the bottom. If your local paint store/Homies will shake it up, pour in a little thinner first.
Try it on an inconspicuous location and see how it dries. From my experience with trying to use old paint that my dad would never throw out, I would guess that the oxidized carrier will result in a sticky finish that doesn't dry.
