Failed emissions (on NOx) by a hair. CT state emissions test.
Other pollutants well within OK range.
Had tranny fluid leak spraying onto exhaust pipe near cat converter and O2 sensor.
Fluid leak is now fixed.

Car is normally fed on 89 octane.
What octane should I feed it for the retest??
Has new 92ºC thermostat.

Good independent Volvo specialty shop found no apparent problems in fuel/ignition system while doing tranny leak fix. Recent tuneup, good hoses, etc.
