I learned this since I owned my 06 G35 coupe. Both Infiniti and Nissan techs didn't recommend me to use synthetic oil on the VQ engine. Because our motor eats oil like crazy. I'd rather top it off more frequently then being regret too late. A couple of my friends used synthetic oil and didn't check it for more then 8k miles then they got the CEL due to the oil being low.

So if you do use synthetic oil, you need to check the oil level frequently like Chuck suggested.

I won't use M1 because it burnt like crazy in my Subarus. Switched to Rotella synth, no more issues. But I'm not starting an oil debate.

So maybe this is an issue with a faulty part, not all Z's. my 09 never lost a drop ether and I had that car for 30k miles.

Many performance cars burn a little oil without anything being faulty. Some of it is blowby into the PCV system as well. Check it at least every other tank of gas. No one is that busy that you can't manage to find five minutes every couple hundred miles.

It is somewhat confusing but the "brake" pedal is in the middle. Same concept applies to this pedal as when used in an automatic transmission.

Running oil for 10,000 miles results in $hit "breaking." Good luck with your braken motor.

Check your damn fluids, people.

There is a technical service bulletin on this issue. I had the same problem and did an oil consumption test. The short block was then replaced by the dealership under warranty.

I was under the impression that was for 2009 Zs. OP's got a '12. 3 quarts in 10k miles is basically about a quart between oil changes, which most likely wouldn't meet Nissan's definition of excessive. And there's no chance of a warranty replacement with the fact that it was 10k miles since the last oil change.

Mine uses about a quart every 3k miles. I fill it to the top line when I change oil and when I change my oil at 3K miles it's at the low line. And an oil analysis each time shows that everything is ok.

10K miles, I'd love to see an oil analysis of that oil.

im at close to 60k and i get about the same result. im outa warranty so replacing an engine isnt exactly something i want to think about.

good to hear others are burning the same amount.

Who would run that kind of a check?
I want to know too..

Funny how some are very helpful and other just want to rub sh!t in. I never wanted anyone to pat me on the back. I know its my fault and I take full responsibility.

I also dont know if it was 10k miles.. I am guessing. I travel so much, work a lot of hours.. it just kept slipping my mind. I am all over the place. But I do know it wont happen again.

If my car is screwed, I will just buy another one.. but I hope i dont have to go that route.

Here's a helpful tip:

MAINTENANCE:
The maintenance intervals of the following items
can be set or reset for the reminders.
. ENGINE OIL
Select this submenu to set or reset the
distance for changing the engine oil.
. OIL FILTER
Select this submenu to set or reset the
distance for replacing the oil filter.
. TIRE
Select this submenu to set or reset the
distance for replacing tires.
. OTHER
Select this submenu and set or reset the
distance for replacing items other than the
engine oil, oil filter and tires.

You can setup your car (Vehicle Information Display) to tell you when your due for your next oil change. Only takes a couple of minutes and can save you a lot of problems later. Complete information can be found on pages 2-15 through 2-22 of your owners manual.

Thanks!!

My good friend, jiuJitsu student is my mechanic at Nissan. He told me he programmed it to warn me. When I checked my oil, I went into the computer and it was blank. He has programmed it before, but it was as if the computer had no information at all.

If the battery is removed does this get cleared? Anyway, I wont rely on that anymore. I will always check when I gas up and I will start writing down the miles.

I would think so. That may be your issue.

Chuck33079 · 09-11-2013, 10:51 AM

It's most likely going ot be full of bearing material. It was diluted with three quarts of fresh oil, so I don't know what will show up on the UOA. My guess would be it's time to set aside a shortblock fund and hope the VVEL isn't gummed up.

MJB · 09-11-2013, 04:34 PM

Mine burns a little oil as well. I switched to 0w-40 and I only burn a little less then half a qt between oil changes.

MJB · 09-11-2013, 04:42 PM

I forgot to mention, I was talking to the mechanics at UPREV last year and they were telling me with how high our compression is, combined with high oil temps, 5w-30 thins out to much and thus we get more blow-by. I noticed when I was using Mobil 1 5w-30, I was losing about a qt every oil change. Switched to 0w-40, which doesn't thin out as much at operation temp compared to 30, which I seen a nice improvement .

Any car ever? How about a RX8?

In all seriousness, a lot of oil consumption is blowby, not the engine burning oil. It's not ideal, but its perfectly normal and a certain amount is to be expected.

chii370 · 09-14-2013, 10:24 AM

lol the RX7 and 8 are a special exception. Thats just again... a design issue. nothing you can do about a stupid idea. Do you without firing up google even know what blowby is? no its NOT ******* NORMAL. its a clear indication of worn or improperly sealed/sized piston rings and if thats "normal" for a VQ engine that simply implies an obvious design flaw. with the correct tollerances, correct viscosity oil, good seals and properly sized rings and pistons a car will NOT have blowby. at least not in any measurable amount, ESPECIALLY QUARTS of oil per X time. we are talking fuckin teaspoons of oil over thousands of miles on a properly designed and maintained engine. Hate to bring up the same example again, but my 45 year old 302 is obviously inferior quality and technology compared to a modern engine, and aside from oil changes ive NEVER had to put oil in it. If your losing QUARTS of oil even over the span of a year, somethings wrong. I never added oil to my 09 once ether in its 40k miles aside from changes....... not sure how much more clear cut the answer can get.
