14 is the high side of around town, most of the time, (i was getting before the lim job) 10 to 12 was the norm. now if it drops to 12 it comes back up to 15/16. it never did that before.

and ive read a list someone posted that o2 only last for 60, or 80,000 miles, ( dont know how true that is) i got 225,000 almost and no service records but my own. figure it cant hurt.
