I replaced an unknown brand, made in china and mileage air filter with a new Purolator A35642. I was seeing 19 to 20 mpg depending on driving situations. Lets see how she performs now.

Agreed, I know I should have replaced the air filter at the first oil change. However, I was battling misfire and P0420 codes a couple weeks after purchase. I'll check back in on this when I go to fill up the fuel tank again. I topped off the tank today, along with second oil change.Air Filters along with an oil change should be the 2 first things you do/check when buying a used vehicle. Make sure it is breathing decent, and you have a fresh baseline.
