It's funny. Out of the 40 odd responses you got for your original question (how do I know if the car has oil consumption problems, only one (Gothchick) answered precisely and to the point!

BTW - what'd u get? How much?

 

Compression test will determine some causes of excessive oil consumption but not all. I've seen cases where worn rings that caused blow-by allowed normal compression test results due to the presence of oil (and its viscosity) on the cylinder walls during cranking. Other factors include high engine vacuum or negative pressure points that draw oil past seals that measure perfectly under positive pressure or compression tests.

But generally, compression testing is the standard for determining the cause or source of excessive oil consumption.

 

I've had an o5 and now have an o6... I love the 06 much better. And whats all this talk about oil consumption.

 

I have an 06 mt that has 5k miles on it now and after the intial breakin where it burned 1/4qt in the first 2k miles it has burned none since then.

 

I have an 06MT and babied it for the first 1200 and at the 2100 mile range...I checked my oil and it was indeed 2 entire quarts low. I'm at 2253 right now and watching it more closely. One thing I must admit is that I never looked at the oil level when I bought it to make sure it was in fact full. So, I'm just in the watching stage right now. If in fact is was full when I bought it, 2 quarts of oil in 1 and 1/2 months seems a little excessive to me!

 

I have an 06/6mt bought in April of 06 and no oil comsuption yet with 15000 on the OD and I beat on it daily. That is what I got it for. If I wanted to drive nice I would have kept my civic. My dad's 02 WS6 Trans Am burns oil and has since new but never hurt the car with now 102000 on it and he steadily beats on it.

 

When I had a 85 RX7 that thing would burn couple quarts every 3k miles. I never had to change the oil since it always had fresh oil in it. Only need to change out the filter.

That being said my 06 born date 10 or 11/06 burnt around a quart in the first 3k miles and a 1/4 in the last 1200 not enough for me to care.

 

Yah... me too. Changed oil at 1,200 miles and 3,750 miles. I got 4,700 miles on my '06 and no issues yet (knock wood). It's a 6-speed manual tranny yah.

 

i've got an 06' 6MT and have never had an oil consumption issue... runs like a champ...

 

ok let me just say i waited three years to get my z and i bought a 06 lemans with black inter,6mt and it had 5000 miles on it i was there when the first owner brought it back(older guy then me) i did not get to talk to him but I got a great deal on her and it was eating 2qts every 1k and I brought it back and told them of the prob they put me through and oil consumption test and bingo it was a problem and guess what nissan put a new engine in it for me no ?'s asked now shes got about 2600 miles on the new engine and i broke it in just as the book says 1200miles then i got on it hard and ran it a little.first oil change it ate 1 qt of oil at 1100 miles next 1000 miles ate 1/2 qt 2100 miles topped it off and 500 miles later has not eatin a thing so yes I love my 06 Z and would buy another you've heard about the problems so just be aware of it and document anything wrong I took pictures of the miles and the oil consumption but never had to use them!!!

 

Correct me if I am wrong, but the 06 manuals all came with the same engine as the 35th Anniv Ed in 2005. And if that is the case, is there any known issues with the 05's consuming oil?

 

I had problems with oil consumption in the first 7k miles. I was driving it kind of hard, and it was during the summertime. It burned 1 qt every 3k miles. I changed to synthetic and my problem was solved. Make sure you change to synthetic.

 

^ that doesnt solve everyones problem. I used amsoil in my last oil change and royal purple before that . The 06 revup engine do have a oil issue .Just look it up.

 

this is not in every case . Im my instance i was having the problem and noticed this thread and the other main thread. The dealership even deemed my motor defective for excessive oil use. Its no myth just a defect of manufactering .

 

truth betold I got mine and had nissan do an oil change right away cause not sure when the first owner did his so I wanted to start off fresh and a few days later had a knock in mine and checked my oil and noticed it was low very low so i thougth they just did not top it off so i did and a week later same thing, then just have became a member searched here and saw i was not alone so I got as much info on it and went back to my dealer they did the consumption test and saw it as a defective motor and replaced it so if its just mas hysteria in some cases but not mine others must have been truthful too maybe not all,but the paper work i have from the dealer shows it is real!! but with the new motor just seems to be a thing of the past! Thanks 350z members for helping my problem to be solved

 

^ yea that picture is my cars life now. Im actually thinking of buying a bike instead of modding my Z....because im turned off. for the moment.

 

bro isn't nissan putting in a new engine if they said its defective? At first i was feeling really let down cause i worked so hard to get the car and I thought i was just going to be jerked arround but new engine and still in love just don't tell my wife she's still a little jelouse of the car!!

 

there is no proof that nissans replacement engines are not defective

 

yet this could be true, but I have a replaced motor with 2510 mile on it and so far everything looks great been checking my oil and it seems to be going in the right derection oil consumption slowing down it went 1qt breakin period 1/2qt next 1k and so far not a drop more after topping it off so I keep my fingers crossed and hope for the best good luck bro with yours hope it works out for you it was atleast worth the try I think but if not then nissan should put in a new motor or buy the car back fair is fair

 

thanks man. I already have a case with NNA and already have established communication with the manager. Right now im just waiting for my call back on whats going to be done.
