I used to be in your shoes with the oil usage. I never had a car that used so much oil, but the manufacturer says is normal, so normal it is (for the mileage and age of the engine).
I have posted this before, and will repeat it here:
I started using Valvoline Max Life or Castrol High Mileage (both 20W-50) @ every oil change. And the consumption has decreased from 1Q every 750 Miles to 1 to 2 quarts per oil change (3K miles) depending on how "spirited" the drive is. It took 2 or 3 oil changes before I could realize the reduced usage. (I am not affiliated with Castrol nor Valvoline, not even stock options)
The car recently passed the NYC emission inspections test (with honors), if it is burning oil, it is burning it very clean
I do have an oily "sweat" on the right-front side of the engine, but it never appears to get worse (or better).
