Why do you think this is? My newly built motor has been using a bit of oil, pretty much only on decel. It was .25 of a qt low after 500 miles of break in. Kinda of like stem seal leakage, but those are brand new and of the supermiata variety and were installed by a reputable shop. Of course that was the first 500 miles of its life, so hopefully the usage goes away entirely.
Stock - rebuilt motor? Or just a stock junkyard motor? How many miles are on it? Maybe it just needs some more miles on with lots of accel/decel.

Any built motor is going to use *some* oil. My Built engine with Wisecos used 1qt over the last 2500 miles. Granted 1300 of those miles were for the Gap trip and it got run really hard for many of those miles spending a ton of time in boost. When i drive it less aggressively it uses very little

So if you drive it super hard in boost constantly it never even used a drop....alright. Then you have a better ring seal than I do I guess, every built motor with forged slugs Ive ever had will use some oil not a lot but it happens. Have you driven your car on backroads or the track constantly in and out of boost going WOT for hours on end? I bet you would use some oil, its nearly impossible to drive a car that hard and have it use NO oil.

Even my race boat motor that runs WOT for literally entire sessions at a time uses NO oil. Even after 2 seasons.
You know what uses oil? my tow vehicle. About a quart ever 500 miles when towing at capacity. But GM will say that's normal. My point is, using some oil isn't that big of a deal.

Yeah... None. Super-tech slugs with Wiesco rings(pretty sure this is what 949 recommends), slaps like crazy when cold. Ebay rods.

You lift, you lose... oil.
Mine doesn't burn oil either. 949 pistons and rings broken in relatively hard to make the Rings seat.
If your rings are set up loose then you will use a little more oil.

I've got about 8 or 9 laps down. Looking good so far.
Couple people who were behind me said they didn't see any smoke, so maybe it isn't too bad on track.
Going to log the next session, and still trying to figure out if I'm burning any oil.
