I don't think anyone is saying that its bad car nor do i think that the issue is related to spending a few bucks to top off oil.

A car that burns that much oil when new might have developed some internal engine problems. Its definitely not the norm for a new 370z to burn almost a quart/1000 miles. Although anything up to that is "normal" by the book, If you are near that 1 Qt/1000 miles, you are already at the maximum threshold and our cars are still new. That is disconcerting for many. What if at 37,000 miles when his car is out of warranty, he starts burning 1.5quarts/1000 miles? Now he needs a new engine and would have to pay out of pocket. Therefore, my recommendation to the original poster is:

1. Go to the dealer and get them to document that this is something you have observed. Setup a schedule where you and the dealer regularly check in and record oil usage. During this time, don't do any of your own oil changes. Just go to the dealer, that way they cant say it was your fault. Also let them perform any topping off.

2. After you hit 1qt/1k, tell them that this is a new car that is fully broken in, that already has reached the maximum threshold of "normal usage". Given that from here it will only get worse, ask them to perform further tests and replace the engine if necessary. Keep bugging them about it.

3. Make sure you break the car in properly before attempting item #2.

FWIW, my car has 8k miles on it and it burns zero and I mean zero oil.

Mine was using oil, but it appears that the usage may be declining. I hope the trend continues.

1 quart first 1200 miles
2/3 quart next 1200 miles
1/2 quart next 1300 miles

I'm down 1/2 qt. in the past 3700 miles since the last oil change. Not too bad.

Your average current consumption of 1 qt for every 1750 miles may not be normal but it is not a cause for concern either, at least not yet. Manufacturers will not recognize oil consumption a problem until it increases to a quart or greater per 1000 miles as has already been stated. If your car is still preforming normally then I wouldn't worry about it. Your just out of pocket a few extra bucks between oil changes. If your car's performance diminishes there may be a co-relation with your oil consumption. Keep an eye on that also.

Checking the oil when you fill up is probably not a good idea as the oil does not have a much of a chance of draining properley in the small amount of time at the service station. Best thing is to check it on a level ground first thing in the morning to get a more indicative reading.

Your checking it after warming up the engine, right?

Why would you do that? You don't get a proper oil reading after running the engine. I've NEVER checked the oil after running the engine.

Just chill out and keep an eye on the oil levels. Man up, be a good owner and take maintenance upon yourself. Oil burn will slow down as you rack up the mileage. At 15,000 miles I no longer burn a material amount of oil. But oil levels should be checked often.

Imo, check your oil every weekend when you check your tire pressures. You guys check tire pressure, right?

I have 3800km or 2361miles on my 370 and it has not lost any oil, including during breakin. I did not baby the car during break in

Same here! But for what ever reason, this car is different when it comes to checking the oil!:tiphat:


Page 285 of the owners manual.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick again and check the oil
level. It should be within the range*1 . If the
oil level is below*2 , remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill*3 .
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the breakin
period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insufficient
amount of oil can damage the
engine, and such damage is not covered
by warranty.

Makes you wonder who's writing their manuals. "Run engine to suck the oil out of the oil pan, then let it sit long enough so the oil runs back into the oil pan so you can check the level." Bizarre. :icon14:

Makes you wonder why you didn't read the manual before jumping on one of those who did. :tiphat:

Is that a piston ring problem? Head gasket issue? If so, it shouldn't be difficult for Nissan to pinpoint and correct it. Cheers.
