A few relics...are they worth anything or do I open and use them?

I recently did a favor for one of my part store connections and bought 7 quarts of old stock for a little over a buck a quart. Nobody else would have bought them. My question is, do I clean them up a bit and keep them unopened (maybe a collector would love these?), or do I open and use them in a very old 1970 vehicle that won't care about the oil's age? I'm leaning toward use them...

If nothing else, I thought a few people would remember these labels and get either a laugh or a feeling of dread knowing how old they're getting!

Here are the goods. Left to right are bottles with API SJ, SL, SM, SN.

Use them . I have a 300 inline Ford F150 and if I had these they would be used for next oil change, notwithstanding that I believe Ford now specs a 5w 20 variety for these old workhorses .

I'd probably just use them, plastic bottles will eventually they'll leak, they probably were spared since they sat on the shelf in a conditioned room for the last 15-25 years, but if you leave them sit around the garage a few seasons I'm sure they'll start leaking out the indicator strip like all plastic containers eventually do.

Very good point...and another vote to use.

Use as a flushing oil. Add a quart of kerosene or 5 minute motor flush, same thing, drain oil, replace filter, use that oil, run the engine for 5 minutes and dump the sacrificial Motorcraft 10W40.
Another decent idea, a sacrificial oil. But I have an application that would love the ZDDP content in these oils, so that's why I was leaning toward using them. It has an 8 quart sump, and I already used one bottle as a sacrificial oil. On something else, so it would have two fresh quarts along with these remaining 6.

Another use vote.
