Any 2011+ owners have problems with Oil Consumption?

Zatanna Z

Any of you guys having problem with OC? There was a service bulletin on the 2009-2010 on OC. I'm either going to get my block replaced or I might trade in for a newer year. So please tell me if any of you are having this same issue!

don't know if it helps, but my engine was replaced prior to me owning the car back in 2011 according to Carfax records. doesn't have any oil consumption issues.

2011, first shipment for the SF area to arrive after the tsunami. I go through about a quart every 4000 mile oil change. Put in 5, take out 4. It has not changed since new. Over 70k on her now.

2013 haven't lost even a 1/4qt with 10k changes and two track days. So happy coming from a vw that used oil like crazy.

Zatanna Z

1qt every 4k miles isn't bad. now one qt every 1k miles that's bad

Zatanna Z

you change your oil every 10,000 miles?

I have had 2, 2012 and 2013 Nismo's. Neither have used oil with a 4000 mile oil change interval.

Yup, amsoil full synthetic signature series. I'll be sending in a sample to make sure it's frequent enough but the two changes I've done the oil looks as clear as when it went in. 10k really isn't bad especially with today's all roller assemblies and high grade oils, hell Honda is running 7500 on dinosaur oil.

Ok actually just ordered my analysis kit, I saved a qt of old oil after last change so I'll see how it looks to verify its good.

OP, it's normal for the oil to go down a little bit between oil changes. For example, when your oil is hot it's letting off vapor which then goes through your intake manifold, and into your combustion chamber to be burned.

Some manufacturers if not all have baffling in the valve cover(s) to catch the oil vapor so it drops back down into the sump and not go through the PCV system with the blow by gases to be burned.

For those that do not know, the PCV system replaced road draft tubes which just expelled blow by gases and oil vapor to the atmosphere.

I was 2 qts low after 2500 miles.... I think that is too excessive. But I got my oil changed the other day and we'll give her another chance and see if she burns again. So I wonder if an oil cooler would help my consumption? Or I wonder if these 2009-2010 370z's just have a flaw in the motor that Nissan never told us about?

Lucky you

Dang that's crazy. Never heard of that before

Don't overfill the crankcase; I put mine up to the circle on the dipstick (about 5.3qts.)
Mine doesn't see a racetrack often-but is driven hard at times.
Taller gears & heavier wheels/tires can add to consumption.
I perform 2500mi. Oil changes with 5/30 extended performance Mobil syn & a Napa Platinum oil filter (made by Wix & designed for synthetic oils)
As I approach 85k miles, I may have to add 4oz. Or so to keep it on the full mark/and this usually doesn't happen till about 2k into the new oil.
When it had less miles (20,30,40k) would have to do this 2-3 times between changes.
Max 12oz. Or so at a 2500 mi. Interval; but it sees 7500rpm's every time I take it out.
And has been to speeds more than I can post.
But seems to have settled down from new on mild consumption.

Really? Every single euro is 10k mi now if not more as far as I'm aware but they all also require full synthetic and run large filters (and not some cheap *** blend synth). According to amsoil (not that I would push it this far) is the oil can actually do 25k or 1 year however the vq37 can only fit their 15k filter. So 10k is still well below the rated mi for the oil. Really when you think about it the filters job it to filter particles which on today's low drag, low scuff designs (all roller, no flat tapet etc) so not a lot of debris and it is the additives in oil that really break down so as long as the additives hold up (which are tons better today than ever before but you pay a premium for them) then the risk of premature wear is pretty low.

I'm curious to see my results, guess will find out.

I haven't gotten to oil change #2 yet, but this thread got me paranoid enough to check:
Car is @15k miles (I got it at 11k)
I set the oil maintenance for 5k miles at my first oil change (pennzoil 5w-30)
I'm at 4300 miles on the counter.
Oil was filled to top circle on dipstick. Yesterday the dipstick showed the same reading, so no oil consumption that I can tell.
DD, no tracking yet, moderate driving.
