There is absolutely nothing wrong with that oil. It's exactly the same as if you had changed it 2 weeks ago and driven 1000 miles. I sometimes can't believe that guys on a car board would not know this.
I just bought a car that has been sitting for ~22 years and the oil is fine in it. I will change it at some point soon in order to get a new filter in it but I could probably get away with just changing the filter. Nothing happens to oil sitting in a closed crankcase in a dry climate.
Now the 22 year old gasoline in the tank is another matter.
