Look at the viscosity and 'SAE'code(s) on the can and compare that to the manufacturers recommended viscosities and SAE specs listed in your vehicles owner's mannual.

This will tell you if the oil is 'recommended' for your vehicle.

The SAE specs do change - but there haven't been any drastic advancments in the last 10 - 15 years with the exception of the new synthetic oils.

It is usually minute changes in the additives.

I'd slowly use it up a quart at a time per oil change along with 'new' oil.

In all my years of driving and building vehicles, I've never seen an engine failure due to the oil itself. Only failures due to not putting oil in the engine!

Later . . .
