370Z - Oil Consumption TSB

4r3s · 09-02-2014, 04:19 PM

meh, an engine eating a quart of oil in between oil changes 3k-6k miles is pretty standard. Nothing to worry about here.

im not too sure about that... but if you're okay with it, then

I'll keep a closer eye on it. I only have to go on what the oil change place says

Early 2011 370Z w/38K miles. No oil consumption. Oil changed at dealer every 3750 miles.
Mid 2009 G37 sedan w/63K miles. No oil consumption. Oil changed at dealer every 3750 miles.
Both vehicles purchased new and broken in according to owners manual suggestions.

Countless cars I've owned in my life have never consumed that much oil. All have used little to no measurable oil and my current Z is the same, no oil consumption.

lachap55 · 09-06-2014, 08:02 AM

are the 2010 build in May, conv-roadstars having the same issues of oil consumption?

olddudesrule · 09-06-2014, 11:39 AM

2012 Nismo. 3700 miles since last oil change (switched to M1 0W-30) and hasn't burned a drop. 14K+ miles on the engine, so I'm not surprised at all.

Justice97 · 09-06-2014, 01:59 PM

2011, just over 34K on odo.
Every oil change has been the same, zero oil consumption.

4r3s · 09-12-2014, 12:44 PM

I had zero oil consumption up until 40k miles. Every oil change for me since then, 6k intervals, has been 1/2 to a quart low. All my previous cars did the same thing as they got higher in mileage. Maybe its me, but if you google the issue or take the car to a mechanic they will tell you it is normal behavior. Maybe I need to get my car retuned.

2009 here with 24K on it, zero oil usage between 3000 to 3750 mile oil changes using PYB Baby!

For reference, Porsche will tell you that 1qt/1000 miles is allowable.

So if your Z used "some" oil (or no oil at all), consider yourself lucky.

RonRizz · 09-13-2014, 04:03 AM

2011 with 30k, On my 3rd short block due to oil consumption. first 2 used a quart or better in 1000 miles.. 4k on this block, and seems to be ok. Yes, I followed manufacturers break in BS on all 3

That's the general rule of thumb for most manufacturers. My 2010 roadster started out consuming oil (got it with 2.4K on its ticker, probably with factory fill still and it was > 1qt low when I first checked it). Based on my driving conditions, I run 6m OCIs and by 20K consumption had fallen to 1 qt between changes of about 5K miles.

I have run up to 7500 mi on a OC (always using 5/30 Pennzoil Ultra to date). 38K now, added .5 qt after about 4K miles

This is completely normal for any car IMHO.

Yup! I fully agree about general rule of thumb. I think the "irritation" here is that some engines do not consume and some do consume. If consumption was uniform, then mass confusion would not exist.

Let's put it this way: my synthetic costs me $12.xx/qt. if my interval is 7,000 miles, this would cost me an additional $84.00, mininum, between OC. I would rather be the guy who has no oil consumption.

acceptable does not mean normal
