hi all, i have found 5 quarts of PERFORMAX 100 5W50 and 5 quarts of GEARPLUS SUPER 80W140 while cleaning out my dad's garage and cannot find any info on them. they are still sealed and i wonder should i use them or send them to that oil refinery in the sky. all help appreciated on additive package and oil group etc

Just run the names on the internet search as many sellers don't pull their sheets on these so the 1997-2001 ones are still there.

Looks basically the same as using 6 year old
Mobil 1 with PAO. I'd use it.

5W-50 other same time period SJ syn
Castrol Syntec 180 437 -45 1.2 .10
Quaker State Synquest 173 457 -76 --- ---
Pennzoil Performax 176 --- -69 --- ---

Looks like you'd be covered if Australia ever had an Ice Age.
