Default Forged piston built motors - oil usage?

Just a quick poll... those who have built motors how is your oil usage? Please mention piston/rings brand, your engine builder and also your driving conditions and break-in regimen you followed.

Thanks!

Hybrid with 100mm Wiseco pistons and rings, machine work done at GT Motorsports assembled by Garage Tuning. Broken in with moderate boost and increasing revs working to 15psi by 1000 miles. 3 oil changes during that time.

So far ~15K + miles I use less than a quart/3000 miles of normal driving. Slightly more when I beat it. Consumption varies with oil brand but the last two changes have been with Mobil 1 5w-40 and consumption has been the best its been. At almost 2K miles and still at F on dipstick.

Note: also running Crawford air/oil separator.

i have about 9,000 miles with wiesco 99.5 drop in pistons and rings. i use virtually no oil, its less then a 1/4 quart even 3000 miles.
for the break in, first 500 miles was less the 3000rpm and less the 5psi. every 100 miles after that i raised the rpm up 1k and slowly turned up the boost.
i use castrol gtx oil.
