Where is the oil going?

Since you've eliminated most of the major players, and since your engine doesn't smoke and the plugs look fine, it's probably just a characteristic of your particular engine. I wouldn't lose any sleep over it.

From what I've heard, many new car manufacturers won't even consider a quart of oil every 500 miles as being unusual. And that's Toyota, BMW, and Mercedes.

In past years, the manufacturers would generally consider anything more than 1 qt/1000 mi to be an issue. These days tolerances are better. My daily driver, which is a BMW twin turbo with 113k miles, uses about a half quart per 7,500 miles. My other daily driver, a Chevy Truck, uses the same or less. I think 1 qt/500 mi is a lot and I would try to identify the issue.

What's cheaper, oil or an engine overhaul? Ditch the PCV for 500 miles and see where you are maybe, but if the smoke and puddles don't embarrass you, it's not burning or leaking enough to worry about.

Mine uses about 1 quart to 700 miles...more with more time at redline. Consider it a continuous oil change.
