I recently came across an *old* print ad for Mobil 1 (late 70's-early
80's?) that stated their recommended change intervals as one year/25,000
(!) miles.  Current ads & their web site only state 'follow manufactures'
recommendations'.

FWIW, I change oil+filter every 5K  (Mobil 1 15-50, & Fram yes Fram!).
103K on the '87 2wd, 160-168 all 4.
