I'm new to the forum, and I did a little searching about the oil consumption I'm noticing in the 03 maxima I bought a few months ago. It has 87K miles. I like to drive it hard from time to time, and I don't mind checking the oil at every fill-up. I don't really want to put a catch can on unless I have to. If I have to add a quart every 1000 miles, then so be it. I was hoping to hear from others with this issue.
Is 1 qt. per 1000 miles normal with hard driving?Does it keep getting worse?Thanks in advance.

Re: Oil consumption VQ35DE (6spdmax)
Sounds like you have a lemon.
The FWD VQ35DE's don't seem to be affected by this (usually), but there are a tiny handful (well less than 1%) that are. This problem is much more prevalent with the `05+ Rev-UP VQ35DE's in the 350Z/G35.
It's cheaper to add oil every 1000 miles than it is to buy a new engine, so I would just keep doing that. A tiny handful of VQ30DE's have done this too, but the number is so few no one mentions it.
If you're really curious, have a mechanic do a compression/leakdown test, although with the way the intake manifold is designed, it's pain in the *ss to do that. If your compression results are not good your piston rings are probably leaking, but again I wouldn't worry about it unless you think you're seriously down on power or you feel like spending $$$$ to get a new engine installed.

Is it still under any kind of warranty? That level of oil consumption has led to warranty replacements of VK45s.
