The oil filter is located at the bottom of the engine just forward of the oil pan. Look for a round cylindrical object. Unscrew it, coat the rubber gasket of the new one with oil and fill the new filter, and screw it on. Hand tight, then a skooch more. Don't muscle it on, or you won't get it off next time.

The oil capacity of the 4.6L 32 valve Northstar in a 1997 Cadillac is 7.5 quarts.

If it is the same as the '94 SLS Northstar, Its under the intake manifold. Sounds crazy, but true.
Depends on the model
it should
Behind the driver, under the vehicle. how do i change it
It's a good engine, just bad to work on.
The era gap is huge when considering a 1990 Deville to a 1997, no way is it possible unless you have tons of time to make extreme modifications and LOTS of money.
