not ideal, but as folks have said it's better than being really lean.

Default if your running ruch your not maximizing performance potential, but you are safe.

lean = kaboom

Default Check your plugs or your O2 sensors, they'll tell you the real story. I don't think you can judge..

if your car is running rich based off of carbon/soot buildup on the exhaust tips.
