And no leaks that I can see or smell of burning oil.

 

How many miles since your last oil change? I have noticed that when I hit around 3K miles it will start to burn a little oil and need a full quart to get it back in a normal range. I need to start changing my oil around 2,500 - 3K miles and I dont track my car....just a DD.

 

That can't be right. I do my oil change every 10k or after every track session. And never had this problem. Last one was 8,000kms ago.

 

are we talking about engine oil or trans oil?? I"m confused

 

Evaluate your drain plug and check that everything is secure.
I would not worry. The R35 burns oil expecially during high way pulls or spirited driving.
I check my oil all the time and I usually need to add some.

Just watch temps and pressures.

 

Wasnt aware thr car burned oil up?!?!?!

 

Engine oil

 

my 370z would consume a quart every 3k miles,so i check my gt-r once a week and have not noticed any oil consumption.

 

^^^ Wow good info I will stay on top of mine now.

 

I beat on my car from day one and will have the oil changed between 5-6k miles and I have never had to add a drop of oil to mine. I just checked mine, its 4k miles since the last change and it is right in the middle of full and add. Also when i have mine changed they do not top it off to the full mark it sits a bit below as recommended in the service manual.

 

What brand of oil are u using?

 

probably, blow-by?

 

turbo seals we started to us oil it was the turbos and 8000 miles is destroying your motor oil additives start to break down at 3500 miles +- and filter can not be ran that long motor will start to bypass the filter as it becomes restricted do an oil analyst and it will prove it

 

But this is the first time it happens in a span of 45ds. Not only I didn't drive WOT but it is unusual. I have had the car for 4yrs and have 100k on it. Oil changes and tranny fluid change are on schedule.

 

Always used Mobil1

 

I find it odd that with normal driving, not racing around a lot or track days, the op is loosing oil. I drive like a beast often. I change my oil every 4k instead f the recommended 6k. For the first 4k and 8k oil changes, I had no indications of oil burning at all. All of a sudden at 10,100 miles, I noticed a warning that there is low oil and to change the filter. I realized that the automatic warning in the dash of the car (set at 6k) wasn't updated at the 8k oil change. This makes perfect sense because 6k miles after the 4k service is roughly 10k, hence the warnings. Here is where it gets interesting. I updated the dash computer warning in the car, but the next day it said that the oil level at start up was low, visit dealer. It indeed was low on the dipstick, so I added a half quart, then later the rest of the quart to make the level on the dipstick right in the middle of the lil circles. Only difference in the car from the first two oil changes is a tune, e85, ams dp, ams midpipe, 3" intakes, ID1000's, and pumps.

My suggestion would be to have everyone, no matter the style of driving, to check their oil every few weeks to be safe.

 

I thought under hard driving the Mobil 1 sheers or something so it ends up breaking down a bit causing slightly low oil levels? Usually have a few hard mountain drives or a track day or 2 I'll have to fill up half a quart. Never thought much of it. Maybe I should send in for oil analysis?
