[Following other replies.]

I moved from a pretty dusty area to a clean area--then noticed the same
thing. I thought it was the heater core at first. It went away when I closed
the outside vents. In the end I decided it was the exhaust from other cars.

I've been told it's worst when people mix brands of gas on a 1/2 full tank.
