On the Scion forum, a person believed that oil started to go bad as soon as its container was opened, said it had a shelf life and began losing its "lubricity", whether it had running time or not.

In the middle of the spectrum, some say that oil loses volume (ingredients) from evaporation, depending on a NOACK rating of volatility.

At the other end, there are those including BMWNA, who say oil can be good for 15,000 miles of running.
