let me bang the oil consumption drum again
ok so i just changed the oil annnnd after around 5k miles i had a little less then 3 quarters left....maybe 2 & 3/4 left...my driving style is spirited at times but the rest of the time i try to be really gentle on the car...and i know that many of you have had this same problem but WHY does it lose so much oil? is it leaking or just burning it up? annnd can i fix the problem? or is it a serious issue the dealer needs to help me with?

i can't answer your question because I'm not a mechanical engineer but I would suggest:
1. change your oil more often. less than 4000 miles per change is good
2. check your oil frequently in between changes so as to notice if there is any need to tip off the oil.
3rd please tell us your vin number so no one buys your mistreated engine 2nd hand lol...

I doubt that the motor is leaking oil: you would see spots in the driveway. There is only one place where oil can be burnt. In the cylinder. Most likely it is getting inside the cylinders because...
The valve seals are not functioning properly.
The piston rings are not seated properly.
And yes this is serious. Oil consumption will not get better over time - just worse.

What year is your car? Im guessing 06. Call your dealer and get a consumption test. Dont let them make you beleive that its normal, because there is no way that it is. Im calling this week to make an apt. for my car. Hopefully you can get a longblock

i've had my share of oil consumption test from my local dealer... of course no problems found according to my dealer ... this morning i checked dipstick and found no oil. so i put in my extra qt i always have and drove to near shop and filled up 4qts. i only drove about 2200 miles since last oil change. i even got a oil cooler to see if that would help but seems like its not helping at all... i have aftermarket headers and don't know if they would hassle me with that and oil cooler...

I used this method precisely because I wanted good piston ring seal. The 350z is the fourth brand new car I've used it on. In every case, I get zero oil use...
Also, Nissan does not recommend any break-in for its new cars, just like every manufacturer I know of. Break-in is a myth, as are 3000 mile oil changes (1 year or 15000 kms oil change recommended for my Z)

My car used 1 quart from 0-1000 miles, 1 quart from 1000-3000. I changed the oil at 3000 (5-30 Mobil 1), and now at 7000 (4000 miles) it has used 3/4 quart.
I expect oil consumption going forward will not exceed 1 quart per 5K.

i had a 97 prelude and always did the oil changes around 3500-4k miles. it always had 4 quarts left...exactly one quart low each time.
i always thought a little oil usage was normal for high compression engines. granted, normal would be no more than a quart over 3-4k miles. who knows? i could be wrong and it could have just been because of having a second set of cams in that vtec motor.

It was a painful process, that is for sure.

BREAK-IN SCHEDULE
During the first 1200 miles (2000 km) follow these recommendations to obtain maximum engine performance and ensure future engine reliability and economy of your new vehicle. Failure to follow these recomendations amy result in shortened engine life and reduced engine performance.
Avoid driving for long periods at a constant engine speed, either fast or slow. Do not run the engine over 4000 RPM.
Do not accelerate at full throttle in any gear.
Avoid quick starts.
Avoid hard braking as much as possible.
Do not tow a trailer for the first 500 miles (800 km)
