The rest of the issues- "smoke", noise, etc, are more than likely moisture evap from the exhaust and the HR "hiss", based on what has been discussed so far.

OP, keep an eye on your oil level. I would consider a quart or a bit under that (the distance from L to H on the dipstick) "normal" for around 5k miles of driving. More than that would warrant more attention.

lol...

The car was running great until about two weeks ago... Then I started to notice strong smells of burning oil. Now a few weeks later it burned through most of its oil.. with only 2k miles between oil change. After 2k miles the oil shouldn't be dark black, something is definitely not right. I highly doubt this is all attributable so lube-x, as far as I can tell the only thing they did was put 0w30 in the car. (To be fair I asked for the best synthetic and in their minds it was 0w30.) 0w30 and 5w30 should both run well in the car. Do you guys hear the hiss I'm talking about when RPMS drop in your engines? It almost sounds like an aerosol spray, I know the engine is noisy but i've never heard this sound before.

Thanks for the replies, Lube-x had done a great job over the last year on all my other vehicles, I always used the same technician and trusted him. Obviously I won't be returning there.

as far as changing the oil myself, I don't have any real way of lifting the vehicle to get underneath for a proper job. How do you folks lift your Zs?

My main worry here is nissan will try to void my warranty, I am an American living in Canada, I bought the Z new and brought it to alberta but I am still the original owner. The warranty booklet clearly states that you must sell the vehicle AND register it out of country to void the warranty which I did not. We will see how it plays out, I am going to be taking it to the stealership soon to have an oil consumption test started. This may take a while to resolve as the car will be stored for the winter in the next few weeks.

It sounds like you have noticed a change/problem with your car. Take it in and let the dealer start a consumption test like a lot of us mentioned. As for the hiss maybe you have developed an exhaust leak if it is worse then normal.

Burning up to 1 qt of oil per 1,000 miles is within acceptable tolerances.

Even hyper exotics are allowed to burn up to 1 qt per 1,000 miles and the manufacturer is off the hook.

Keep track every 1,000 miles of how much oil you are burning. If it is less than 1 qt/1K miles, there is nothing the dealer will do. (My 2nd 350Z was a notorious oil burner so I have been through this dance before) You will just have to keep adding oil. If it is more than that, then the dealer "should" (doesn't mean they will) do something about it.

(Side note: If you can see white smoke coming out the tailpipes, that is not normal. This should be shown to your dealer right away.)

Sorry.

Sorry.

Luckily for the OP, or anyone else who may be experiencing oil consumption with the VQ37, the information above is completely incorrect.

Please check the TSB issued for the VQ37 regarding acceptable oil consumption.

This is from Infiniti but it's basically the same thing as Nissan. The nissan one is on this site in the TSB section but I'm lazy.

Sounds like they fooled you, like they tried doing to me. I have a car 8 years old Turbo'd beat the hell out of that does not burn this much oil.

Nobody "fooled" me. I was not happy but they wouldn't budge. What else could I do? It's just a car. Not worth the aggravation. My concerns were documented.

I had to go through the same thing. The first dealership I went to about my '06 Rev-Up eating oil told me that 1qt per 1k miles is acceptable. They didn't have much to say when I asked why, then, would Nissan suggest up to 7500 miles between oil changes.

They even went so far as to overfill the engine by a quart during the oil consumption test. On moderate acceleration, oil would spew out of the dipstick and onto the block, giving me a nice smoke show. Pretty cool, huh?

Luckily, the next dealer I went to went ahead and replaced the short block. Problem solved.

I'm going through it again now, though- about 1qt every 750 miles.

I'm personally not going to be that sad to be the VQ35/37 go.

If you are smelling buring oil that is bad. If you see oil smoke at star up that is bad. Sounds like you could have a leaky oil seal in one of the valves and or even leaking head gasket that is allowing oil and air to escape from one of the heads.

I would get it in quick. The warranty will cover it all and you get a loaner.
