Daox, my car's never been smog tested before. New cars get a 5 year exemption from smog testing in CA.

FWIW, here's how I view my fuel consumption/emissions footprint. My xB has 2008 EPA estimated 26/30/28 city/highway/combined fuel consumption estimates. Since I bought my xb, I've averaged 49.4 mpg for every mile I've driven in it. I've used 590 gallons to drive ~30k miles, saving 450 gallons compared to the average xB driver. I used 55.7% of the average xB's fuel to go the same distance.

But, as seen above, I'm dumping 3-15 times the average hydrocarbons, 4-7 times the NOx, and up to 6 times the CO of the average xB, when my cat is lit, which is almost never, in local driving. Even if I use 55% of the average xB's fuel, it's inescapable logic to me that I'm producing ten times as much air pollution with an unlit cat. Preheating the O2 sensors doesn't fire the cat. I have to run the engine constantly to keep it lit.
