BaaaaaAaaaaaaHHH!!!!111!!!one Humbug to all that noise.
But my refute is purely anecdotal and based on previous and current personal vehicle ownership.
My current manual states, "Oil *AND* oil filter must be changed @ no longer than 7500 miles and/or 12 months. Whichever happens first." She's a nasty, biggest of the small block mini-monsters. Guaranteed at about 6k Miles into an OCI, her clock's runs down on the OLM to 10%. Happens faster in the cold and frequent but short trips in the cooler temperatures. She adjusts for ambient block, intake temperatures, cold start frequency, how many LBS. per/minute you flow trough her throat.....yadda yadda yadda, blickity-boo.
Cold weather, short tripping, # of cold starts within a given OCI, how many thousands of liters of air and fuel mixed and burned at what rate and temperature, (And ethanol percentile) loading, throttle % all counts against you. It's a penalty system. She starts optimistically at 7500 miles but *PENALIZES* you for conditions that could detract from oil lifetime and usability as determined by research and careful engineering.
Oil is exposed (indirectly) to temperature and moisture even as your engine sits idle in the elements. It might be "easier" if your machine is shed/garaged stored without direct impact from the elements/weather. If you're a total plebeian like me, you're parked out on the tarmac whilst Mum's garage queen is snug in the garage. (Admittedly, my machine doesn't even fit anyway, so she can have it.
)
She ticks down like a Corvette even if you don't run her and like it or not - even if you do NOT clock engine running hours? She'll Poo-Poo your current oil fill on the clock as a calendar year may have passed. On *some* GM vehicles, it's not worth changing oil before winter storage. She could and may expire your fresh sump and go into limp mode until changed/reset with fresh oil.
Conversely, you could just lie and push the menu buttons to indicate a fresh oil change.
Be it on your head, mates!
(I personally think that if they bothered to engineer a time sensitive aspect of the GM OLM into the "cloth" - it merits a thought. Especially if it's a treasured to you machine. Treat it well and it'll always, without fault; get you home.)
Edit: Four schpiellingh and g8ter grahmmer c00rekshunz! I might have also slipped a little Harvard grammatical style in here, somewhere. BUT - you may not even know.
