Some makers say five years, but we have members here who've run oils much older than that without any problems.
Yup! I'm using oil from 2006 in the Acura and oil from 2007 in the Firebird right now. No issues to report. After about 3,000 miles on each fill, they haven't sludged or caused any issues. In fact, the oil still looks fairly golden on the dipstick and hasn't darkened all that much.
