Excessive oil consumption?

Remember also, that the 1200 mile break-in is just a recommended number to get everything working well together. Gears, differential etc. Many motors take well more than that to truly beak-in and stop using oil. 5, 10, even 15K is not unusual in some cases..

The only vehicle I have heard of that stopped using oil 5K miles or later in life was a BMW motorcycle with their crazy hard rings/walls. If the car is still using after 1200 miles I would suspect an issue.

It's pretty common with modern tolerances.

That has not been my (albeit limited) experience. Then, I have only owned one BRAND NEW car, so I am at a bit of a loss there.

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?

on the S, there were guys that saw oil consumption for the first 7k, then went on and have 150k+ with no issues.

S2K did not have conventional cylinder walls, either. IT falls into the category of the BMW motorcycle as an outlier. The 370Z has steel-lined aluminum cylinder walls and hypereutectic pistons along with plasma-moly rings, no?

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

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!

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.
