oil consumption on a new engine
when does the oil consumption start to go down on a new engine build?
so far i have about 1600 miles on the engine and am running 10w30 valvoline....and its using about 8 oz every 300 miles....its not leaking and its not burning it.....i know i have a really strong PCV vacuum....so anyway when does the oil consumption start to taper off?

My new 383 both leaked and burned a bit of oil for the first 500-800 miles.I had many people tell me "that ain't right" or "thats perfectly normal till the rings seat"-----Now at about 1500 mile it's not burning or leaking anything.... 
So from experience I thinks it's pretty normal....I wouldn't worry about it unless it pretty severe.

Yeah, normal for now. Probably the rings haven't set just yet. My dad had one that took 3-5k to seat fully and stop using oil. Im sure you've already done it, but continue to do the "engine break-in procedure" drive at cruise speed then accelerate and keep changing RPMs to help the rings set.

I used to use about a quart every 500 miles (extrapolation since I never let it get down a quart) in my new engine but I just did 230 miles this weekend for the tuning with Lars and there is no appreciable drop in oil level.

I would guess it's burning it since you would be able see it if it leaked. One quart per 500 miles is still considered acceptable. I would think a quart or less per 3000 miles in much more typical for most engines.
Is the engine using forged pistons? They typically will burn more oil than cast.
