The Oil Level Low warning does not come up until you're missing 2 quarts. The dipstick range from "full" to "add" is designed so that when it reaches "add" it means it's low 1 quart.
The engine may be dirty, and the dirt and old oil may smoke when the engine gets toasty.
I used to have a similar condition when my oil cooler lines were leaky. Put your car up on ramps and look in there with a flashlight.
It may help to use "brake parts cleaner" to remove the buildup and oil, on the underside... wipe it clean with a rag... then check again a few days later so you can see where the problem is.
