Have not changed the oil. This would be a good time (and reason)to change it, though. Thanks for the advice.
I'm just wondering about how the NO ppm went from well within specs to way high (301 ppm to 1067 ppm).

I did bring in the car HOT! I drove around town about 45 before the test.
I'm glad the HC's went down, but why the hugely elevated NO?
