Even though I have this problem with my 4 month old Z, I'm trying to not make a huge issue about it at the moment and stress over this and post a lot about it but I need to know something.

For those of you that got new long or short blocks or whole new motors, what was your oil consumption rate?

The majority seems to be that Nissan says 1 quart per 1,000 miles is acceptable.

I personally think that is a joke.

 

+1..... one quart per 1k miles is a bit excessive, unless you have a +150k miles on the vehicle and still running 5w30. In my 10 year old Eclipse I ran 20w50 and lost about 1 quart every 2k miles.

 

I have a '97 Nissan P/U 4 banger 5 speed that I bought new, have beat on it hard unlike my Z and it has 132,000 on the clock and it sips oil. I have honestly gone months without even checking the oil in that thing.

I think that for a brand new $30,000 car, that anything over 1 quart in between 3,700 mile oil changes and MAYBE even go as far to say every 3,000 miles would be ok as long as it doesn't get worse but 3 times that amount of oil is insaine, right?

 

yeah I had a 2000 vw vr6 gti that didn't burn a drop and every time I ever did check the oil it looked like it just came out of the bottle. My z burns it like crazy and it gets all dark and ugly. Theyre gonna do a consumption test, but I dont think its looking too good. I swear it's the ghost of my v-dub gettin' even with me.

 

Got a new long block on an 06 at 8000 miles after a consumption test (1qt/500 miles). 4500 miles on the new block, but still consuming about 1.5qt/1000. Thinking it's my driving style, but can't bring myself to drive "break-in period" gentle to test the theory out... I’ll probably keep driving it like a sports car and take it in if it gets any worse.

 

I don't care how your driving style is, it shouldnt burn oil like that. That is beyond excessive. That sucks that the engine replacement didn't solve it. I'm in the same boat and I'm lookin for some comforting news and I'm not finding any. Where's my gun?
