Apparently, you did not read the OC thread. There is a good explanation of how much oil it takes to go from L to H. HINT: It is more than 1 QT. And no, the dipstick was not redesigned on the revup, it still sucks.

Yep. You have to have a HR motor to get a decent dipstick nowadays!! LOL

I've read the OC thread. Have you? In particular, please check out Gothchick's oil consumption chart that has been added to the very first post in the thread. If you'd like more details, there's an exchange within the thread concerning the chart that's very informative, a lot of effort went into making sure the chart was correct. Thanks.

I stand corrected, it is 1QT. My source, later in the OC thread, is probably not as reliable as the Nissan TSB, I think...

Boy, you ain't lying in that one. I really want an 07 so bad. I am begining not to like my 06.

Ehh, enjoy what ya got. I don't think the extras of the '07 are worth going upside down for. Or tacking that many more car payments on when you're that much closer to having your current Z paid off. Now if it was like the GTR etc. then that'd be a diff story!!

^^I do apreciate the encouraging words, it does means a lot. And you are absolutely correct.

I was in your shoes when the '07s came out. I had only had my Z for a few months, and would of taken a huge hit if i had traded it in. I drove a couple '07s, and although they did feel a bit more refined, any brand new car is gonna feel that way, when you're used to driving the used version of it. I figured i'd take the money i was gonna go upside down on, to improve mine. And i've had no regrets!! Seriously, go drive one if you are still wanting one. And try real hard to look past the fact it's new, and you'll realize your Z is just as good!

Ive asked before, with no response I will continue to ask untill someone answers.. are there any long term problems for having this much oil consumption? if nismospeed4life continues to check his level regularly and maintain his level at H are ther going to be any problems?

thanks

Mine still uses oil and the only thing I'm really concerend about is the cats getting fouled up with excess oil to the point that the car won't pass smog in 4 more years when the first smog check needs to be done. It will be out of warranty at that point. Should have put in high flow cats a long time ago and saved the stockers for smog check.

If it doesn't pass due to the cats, even though it'd be out of warranty, might be worth talking to a lawyer about.

As one guy pointed out a while ago, at least the car always has fresh oil in between oil changes, since you need to keep topping it off lol.

- test pipes ftw
- stock cats only for smog tests

lol @ fresh oil

So nothing serious can occur internally over time? resulting in major engine failure etc... I don’t know I’m no mechanic

I would assume if the oil is burning off by blowing past the piston rings, then that would mean you have a loss of compression too. And loss of compression means poorer performance, vice an engine with no compression problems.

I'm not up to date on where the oil is leaving the engine in these cases.

I am one with Doba, since this have been one of my concerns as well. But, loosing compression and horsepower due to O.C. issues is really a problem for sure. I think I will have mine check for the proper compression.

Thanks!

No prob!


You may want to read more posts to find out where the rev-up motors loose the oil from. The VQ's sparkplugs are a huge PITA to get to. And it'd suck to spend all that effort or money doing a compression check, if that's not even where the oils leaks from.

General consensus seems to lead to valve overlap on the revups, causing the oil to get sucked through the valve guides, then out the exhaust.

At the peak of my oil consumption, I def felt a loss of power. I had the oil light go off one time, and I am pretty sure that caused some damage, most likely to the cams.

If you are still under warranty, I would strongly suggest you take the vehicle in for testing.

Best of luck!

When I bought my car, I would get around 28mpg on the highway. 40k miles later on my oil burning engine, I was lucky to get 22. Now, after getting a new engine, I'm at 30 even.

Take from that what you will.
