I would only use it in a car from that same era and then only if I had nothing newer. I would be concerned about inadequate additive package such as detergents.
I had the same Mobil HP container up until last year. It was from the mid to late 1990's. The add packs from that era, at least with respect to phosphorus and zinc, are often stronger than what's put out today for standard SN.

You could get rid of it half a quart per oil change w/o doing any harm. I'd use it up in OPE, two seasons and it would be gone.

Please forgive my ignorance, what's OPE, some equipment?
Is it safe to use?
Yes.
The question is what you propose to use it in.
I'd use this oil without qualms in a couple of our machines, but not in a few of the others.
That era of Havoline was the darling of BITOG for quite a while. It has nearly 400ppm moly in it! That my friend is a find. I would run that in my Jeep in a heartbeat.
The other stuff I'd use for top off for the mower if at all.
