Hmm, my guess is the the "Engineers" change oil in their vehicles more often than the average owner. Also, whatever their best practice intentions for the engines they "design", the message gets lost in the sauce after marketing and accounting get ahold of the language of the service manual.
Frankly, owners on BitOG do know more about their personal car engine, in terms of driving conditions and service needs, than can be written in a single line of a service manual. There are more examples of lubrication failures of engines on recommended service than I can count.
As far as filter changes, I'm doing 3 changes a year on the same filter. Why should I toss a $15 filter after 3000 to 5000 miles? I'm straining to go 3k in 4 months, but it's a lot of short trips so I'm still going to change it 3x a year. A case of new filters would do me zero good.
The idea of "sleeping better" because someone can not offer a better reason to keep changing perfectly good filters is laughable to the rational observer. Same with the failed metaphor of dirty underwear, is that the level we are operating on here now?
