I have a 2006 350z. My question is, what is an acceptable range for oil loss? I currently have about 1300 miles from the last oil change. The total mileage of the car is around 4300miles. I checked my oil this morning and it looks like its down about 1/5 from the H mark. Is that anything to be concerned about? I hope people with oil consumption problems chime in. Other than this concern, the car is doing great. Thanks so much.

That doesn't sound too bad, but if you are concerned, have your dealership begin the consumption test. If you want more info, read here: https://my350z.com/forum/engine-and-drivetrain/232332-revup-oil-consumption-tsb-and-discussion.html

Thanks a lot bofa for the link. I've read that thread completely a while ago. I've also been following your consumption issues. I hope all goes well. I just wanted to make sure I was not showing the same symptoms as those who actually went through the entire consumption test. Thanks again all.

Thanks. My consumption seems to be at the far end of the spectrum, but others began with minor consumption that progressed. My suggestion would be to get the test done just in case.

I just did oil change after 2000 miles, (7300 total on car), and it was a little less the 1/2 quart low.
Bofa, if I may ask, what is your consumption at the "far end of the spectrum" as you say?

Blackstone can also do an oil analysis for you.

My cars only got about 940 miles,but ever since I got it with 114 miles on it the dipstick always read right in the middle of L and H,I kinda figured that was normal,maybe I'll add some oil for the hell of it

My 350Z has 49,000 miles, and I have never added oil.
A motor with 4,300 miles should not burn oil. Any. You know that.

Bofa's advice should be heeded. Follow your oil consumption religiously. Have them do consumption tests at the dealer everytime it seems to be consuming. It is not known yet whether it is a characteristic of just some rev-up engines or, coupled or not, with driving habits or environmental conditions.

You should know what your engine is doing and when. (At this point mine has gone from 1qt/3000 miles to 1qt./5000 miles, but summer's dry roads and tight corners are coming up). Have oil consumption recorded by your dealer while still under warranty.

As far as the consumption tests are concerned, I basically just ask a dealership that I want my car to have the test done? Is there anything that needs to be done prior to actually taking the test? Thanks again.

My consumption rate at it's highest (present) is well over 4 qts in 1000 miles. I couldn't get the exact volume from the dealer, but this equated to my oil level being down 40 mm on the dipstick from the H mark (that's how they have to record the results for NNA)... basically it was nearly bone dry to the point that the engine was pinging.

Tell the dealer that you've noticed a decrease in oil level in your car and have learned from fellow Z owners about the 06 consumption problem and that you want your car tested. That should be all it takes.

I1DER

Holy Cow! I had no idea it could be that bad. Thats about a quart every 10-15 gallons of gas. Definitely right up there with 2-strokes. I'm amazed they didn't just give you a new car and ship that one back to the factory to do an autopsy on it. WTF.

I think bofa probably has the worst case of it,the more I read these threads the more worried I am about my car. You might want to do a search for more oil consumption threads and see who in your area has the same problem so that you can know which dealership to go to.

We're still seeing about the new car... . NNA did take 20-30 engines (don't remember the exact number) for research and that's why some had their engine replaced early on with the issue. Some thought it was to fix the issue when it turned out just to be a way for NNA to waste the consumers' time and patience to research something that should have been done the right way the first time around....many of them are still having consumption issues btw.

quick question....
if your burning that much oil, would your car pass smog?

please dont me for asking

bofa

iTrader: (23)

I seriously doubt it would and I don't think the EPA would be happy to hear about the additional emissions from a production vehicle. However, FL doesn't have emissions testing anymore (since 1999 or 2000 I believe) so I haven't run into that issue.

I1DER

If the same people are having consumption issues with their new engines, while others never have had any, I would think a correlation exists between driving practices and oil consumption. My consumption has dropped with milage, but also at the same time the winter weather here required much more conservative driving. Have you tried driving like a little old lady for a tank to see if it makes any difference? For you it would only take a tank, for me it would take several and I don't have that kind of patience.

It's not that it would make any difference on whether Nissan needs to fix it(they're high-performance sports cars for crissakes), but it would point a direction to the elusive problem. Just a thought. I'll keep following the main thread for developments. Thanks.

I actualy sent an e-mail to the EPA and DMV and posted the EPA's respone in a thread someplace around here.

bofa

iTrader: (23)

Chad, I think I remember that... they passed the buck or something, right?


I1der, I've backed off since I had the initial engine pinging because I didn't want to blow the motor just to start consumption tests all over again on a new motor. I've tried 2x 1000 intervals with babying it and no noticable change.
