No, Not really..... Very few manufacturers will give you the time of day if you're not burning more than a quart/1000 miles. Chevy (for the Corvette) even has a published bulletin that says 1 qt per 500 miles is acceptable if used in an aggressive manner (aggressive being defined as operation above 3000RPM's...LOL). A quart between changes, or even 2 would not be considered excessive enough to warrant correction with most all companies...
When you get into the serious usage area they will do a monitored test by documenting miles and sealing your oil fill to determine true usage..

(Just ignore the idiot trolls)

just checked mine. 6000 miles and 150 from next change. It's slightly overfilled still.

Got me paranoid, especially after owning an '06 OC Z. Just checked the oil level, 2500 miles since the first oil change, 4500 miles total on the car. Level was just below half, approaching 2/3 down from High......... that makes me feel better. A little off topic, but checking the level just now, it has been 4 1/2 hours since I got home, car has been sitting in the garage. The engine was still so hot that it would burn your hand to leave it on any metal part for longer than a second or two. Man, this engine bay is tight and closed off, no heat dissipation at all. Any one else notice this?

Pull all the rubber gaskets across the rear of the engine (they just snap out). They will allow a bit of ventilation, both moving and stopped. I've recorded significant temp reductions on other cars. Things will be a little louder as the gaskets are mostly for NVH, but you might like the induction growl. You can also pop the plastic piece at the rear strut tower mount for even more air. This engine dies not run partcularly hot. I generally see 182 degrees water temps while moving which is pretty cool..

If I pull the gaskets out across the rear, any issues with water running down into the engine bay?

No more than if you drove around with no hood at all.

Apparently you have not tried it. I'd throw some datalogged charts up but I don't think you'd get it.....

Wow ......I check my oil at least once a week.....and top it off if needed. Read the manual............if you dont top it off, you are running your engine with less oil than it is made to have to lubricate and cool your engine !!!

if the car was broken in 'easy' you may have a ring seal issue...break um in hard kids, helps the rings seal

bluzman · 08-17-2009, 08:51 PM

Z Owners, check your oil, post mileage and how far "down" it is...

Lynchmawb · 03-22-2010, 11:13 AM

I have this issue with mine as well just rolled over 10k and after the first oil change at 3000k the oil was gone within 3000 miles... enough of a loss with no warning light to make them replace the timing belt and gear.... 3000 miles after no oil showing yet again on the dip stick... I think this is a major flaw... taking in tomorrow again to get them to fix it... No car should have to fill the oil as much as you fill the gas tank... No warning lights saying its low nothing at all. Guess will be selling to someone else to deal with before the warranty runs out unless Nissan fixes the issues....

NYBladeZ · 03-22-2010, 11:20 AM

~4200 miles, no issues. I have seen as high as 230ish oil temp but upon checking the oil after cool down it is exactly where it needs to be. I drive it hard on occasion but not enough where it is abused, I also stored it outside for 8 months under multiple tarps. Only 1 oil change done thus far, I used Nissan Ester Oil, I know it's not required but why risk otherwise. I dynoed on a dynojet yesterday, I'm happy to report humbly that the motor seems healthy and strong. Not to add fuel to the "break in" argument, but I babied her for the first 1850 like the manual says, many ranges of revs and speeds didn't really hit redline a whole lot, maybe that helped...

Lynchmawb · 03-22-2010, 11:31 AM

As a side note I have owned a 2006 G35 I purchased brand new as well and no issues at all with not driving that car any different than I am today... Almost wish I would have kept it at this point...

NYBladeZ · 03-22-2010, 11:52 AM

^^ I met a guy this weekend, bought a new g35 went through 4 quarts every 1000 miles and Infiniti couldn't solve the issue

j.arnaldo · 03-22-2010, 01:10 PM

I just hope you live near the dealership...What a hassle, going back & forth there!
