Even hyper exotics are allowed to burn up to 1 qt per 1,000 miles and the manufacturer is off the hook.
Keep track every 1,000 miles of how much oil you are burning. If it is less than 1 qt/1K miles, there is nothing the dealer will do. (My 2nd 350Z was a notorious oil burner so I have been through this dance before) You will just have to keep adding oil. If it is more than that, then the dealer "should" (doesn't mean they will) do something about it.
Sorry.

Luckily for the OP, or anyone else who may be experiencing oil consumption with the VQ37, the information above is completely incorrect.

Please check the TSB issued for the VQ37 regarding acceptable oil consumption.

This is from Infiniti but it's basically the same thing as Nissan. The nissan one is on this site in the TSB section but I'm lazy.

Correct me if I'm wrong, but if your engine is burning oil shouldn't you see bluish colored smoke from the tail pipes? I thought if you are seeing a bunch of white smoke than you could have water/coolant in your oil....?

Not necessarily. Carbon buildup (soot) on the tailpipes, however, is very common.

i love how 10 years ago if u burned a quart every 1,000 miles something is wrong with your engine. but now if u burn 1 qt every 1000 miles you are "within spec"

Id say 1qt/1000mi is pretty bad.....

There is no reason to lose faith! You can always do a leak-down test to confirm if the oil is getting past the piston (blow by) which would then essentially lower your compression. We build a lot of STi motors as piston #4 is a common failure point. A ring issue is the most obvious thing to check for oil consumption, just not typically with such low milage. During the leakdown test you will bring the engine to top dead center and make sure the camshafts are in the correct phase. You want intake and exhaust valves closed, and piston at the top of the deck. Then use your leakdown test to force compressed air (typically ~90PSI) through the engine. It will then give you a % of leakage. If you hear it out the intake or exhaust you have a valve train issue, if you feel air or hear air out the oil filler neck that is a piston issue, if it comes out the radiator cap then you have a head gasket issue. I think if you can find a reputable shop to perform the test, then if you had poor results you could go back to Nissan and present your data to help with the warranty claim.

thx for the responses folks. Took her for a drive to the misses family for canadian thanksgiving today.. seemed to be running well. Going to schedule an appointment with a dealership, in the meantime I plan on doing my own oil consumption test. Stay tuned.

I think I may be f-ed though, Pretty sure my warranty is void simply because I'm american and bought it in america and registered it in Canada.. we will see though.

Just a question for the OP:

Are you checking your engine oil after you've been using the car for a while?
You should check the oil when the engine is still cold, or if you've been driving around make sure about 10 minutes have gone by before you check the oil so it can return to the oil pan.

At 2900 miles and 6 quarts of oil, I got a new short block. at 13,700 ish I started a new oil consumption test. Only two quarts in 3700 miles, or was it 3 quarts. Either way I am testing as we speak. I do not want to fail a second time.

about an hour. In that time you can prep a good cherry or blueberry pie and chill it. Give it another hour and serve.

Well Its been a while since I posted on here. Car has been stored all winter.

I think my car has a blown head gasket.

Oil smells sweet.. The coolant is completely burned off (reservoir empty). Really sucks, soon as the snow melts a little more outside I'm taking it to nissan. All I can say is they better repair this right and not do a half arse job. I almost don't trust nissan to take care of this correctly. God I hope the car doesn't need a new engine.
