Mileage is approximately 130,000. It's a bad smog day in my car and smell does not go away with circulating air; windows down helps only a little. I've maintain regular oil changes, just had an oil change and point check..had to replace a very dirty engine filter and inside air filter...didn't help.

You have a bad exhaust leak in the engine compartment allowing the fumes to get into the vent system. Have a shop inspect for the source.
