Hi,
It sounds silly changing oil at certain mileage interval.
Acura oil change interval is not fixed like that. It
monitors engine running conditions and determine when to
turn the code B1(code for change oil) on. Also lot of driver convenience
features can be set to the likings of driver 1/driver 2 separately from
MID. When combined with after market remote starter brain, there are
many useful interesting possibilities.

2001 Buick LeSabre has the same feature (oil %, likes, driver preference, etc).
