<VV> motor oil shelf life - general, not corvair specific

[JVHRoberts at aol.com]

It's fine. Motor oil, especially anything made in the last 50 years seems  to 
last forever on the shelf. My only issue would be it's grade. What are we up  
to now? SH? Higher than that?

Cleaning  out Dad's garage.  Found buncha quarts of Valvoline 10W40 - old  
enough to be in round card-board like containers with gray plastic  bottoms.  
Any opinions on whether this is OK to use?
