Castrol is the best brand and synthetic is the best type of oil, but it is expensive for the synthetic. I would use regular 10w30 Castrol and put Duralube in it every 50k miles. Change oil regularly. The Duralube is the every 50k mile.
The best thing you can do is to look in your owner's manual.
For best performance it would be best to do so every 30,000 miles.

200,000 is the best i would hope for
Automatic trans, 50K, standard trans, 100K.
That depends entirely on driving conditions and the habits of the driver. It is not unreasonable for a 2004 Impala to need new brake pads at 47000 miles. Once the brake pads are worn to the point of needing replacment, you had best get the job done and avoid additional expense.
yes
I would recommend 5w30

The 1996 Chevy impala ss
