Default How long will a new motor use oil?

My new motor has about 1200 miles on it. It's been using a little bit of oil and I wasn't sure if I should be concerned or not. It gives some smoke at wot also. It used a quart this weekend in about 250 miles.

I would be concerned with that amount,even when new it should be tighter than that.

What kind of oil did you use for break-in? Curious.

That's quite a bit, IMO. Do you have an LS6 PCV system and/or catch can?

You can do what everyone told me to do when I was burning 1.5 qrts every 300 miles. Check the intake, check for gasket leaks, stick a Q-Tip in the vaccum nipple, VALVE SEAL AND GUIDES MAY NOT HAVE BEEN DONE PROPERLY, then do a leakdown check.
Maybe your rings didn't seat properly. Noone can tell me that it can't happen to a new engine, it happened to me with my brand new 436 stroker.

Do you blow clouds of smoke when you hit the gas while driving? Do you get a puff on start-up?
