What exactly do you claim is going to change in that engine that has not already changed at 1200 miles that will prevent further oil burning?
Your problem is patience. Give it 5k miles and you'll see (and I'm 100% sure, unless you oil starve the engine) oil consumption will no longer be this "issue" you are concerned about.

And NO, I'm not being sarcastic or trying to pick a fight. Flame me if you want, but the majority, 99.99%, of all oil consumption "issues" are not problems but normal usage because of ring seating.

Again.... if you missed that.... give it some more time!

i don't think the frm walls make such a big difference....

You told me they did. Further, I think the S2K uses forged pistons, no?

My Z06 stopped using oil at 600 miles. Hasn't burned a drop since (at 3600 miles now). I was just saying I have never heard of a conventionally constructed engine burning oil beyond 12-1500 miles if broken in correctly.

You cited it as an example. Can you think of a different example, with conventional steel liners/hyper pistons?

how about the vq35? Well known to burn oil for quite a while...

Does it then stop?

I have read that this series of motors from Nissan doesn't produce peak performance on the dyno/strip until 4-10K miles.

Huh, well if my 370Z happens to use oil, I will give it 5K or so to start slowing down, then. Thanks! :tiphat:

It doesn't for the G35's and 350's. It actually gets worse over. Its pretty lame :shakes head:

Just got my test results back today. I used about 3/4 of a quart over 1000 miles coming up on 5K in my 2010 Roadster. Accoring to the (Infiniti) TSB I should not have exceeded .43 of a quart within a 1000 mile test (Assuming low to high mark on the dip is 1 quart as they measure this stuff with a ruler in millimeters). So they ordered me a new short block. I noticed oil useage leading up to the first oil change that triggered the concern and ultimatly the dealers test.

I had the engine replaced and still same problem 1 quart of oil every 1,000 miles, I hate my car.

See this is what I'm afraid of... my short block installation will most likely be completed today but there is no guarantee this will even fix the problem.

That sucks, what oil are you using/used? Switching to something with a higher flash point would help.
You can also get the oil tested and see if anything usual is going on.
