370Z - Oil Consumption TSB

cab83_750 · 10-16-2010, 01:21 AM

2009-2010 370Z; ENGINE OIL LEVEL IS LOW!

Well, it looks like prior posts here at the370Z.com are correct about the Z's TSB. I, personally, have seen the Nissan Document. (BTW, I like how Nissan titled the document: "Engine Oil Level is Low." In my opinion, it should have the title "Excessive Oil Consumption.")

Please see:

TSB for oil consumption on the VQ37VHR.

At least, for now, it looks like the myth about "Nissan not blinking unless you use 1qt/1K miles" is a bust. Correct me if I am wrong, but between L-H marks is equal to one (1) quart (24mm).

Change your oil and fill to the H mark. Drive and log some miles. Measure oil level from the H mark and see chart below. Note that Oil Consumption test is done by the dealer. Obviously, you can do this yourself as a guideline.

Miles
1001-1500 >=10mm drop from H is a "no good engine"
1501-2000 >=13mm drop from H is a "no good engine"
2001-2500 >=16
2501-3000 >=19
3001-3500 >=22

Hopefully, this is not a re-post, and good news for some members waiting for the info.
cheers!

i check the oil stick and sometimes i cant tell if its ok or not
i have not got a oil light yet tho
just wondering

Oil light has been hit or miss but usually if it comes on it's too late.

You should let the car cool for ~10 mins or so on a level surface before checking your oil level.

I guess it applies to me too, however I'm always checking my car oil level.

Plus I told the dealer the last time about it and they recorded on the car records (Oil Consumption Problem).

I want to revive this thread to help all the unsuspecting '09-June'10 used 370z owners out there cruising the forum while waiting to buy their car. Apparently, there was a modification to the engine in June '10 to help prevent the oil consumption issue. Please, as many of us have learned...the easy way or the hard way(long block replacement=no car for possibly 3months) check your oil every time you fill your tank. This will allow you to enjoy your car for years to come.

kenchan · 03-13-2012, 11:54 AM

i still recommend checking oil level when the engine is cold.

Nick,

How do you figure?

No, not at all. "Normal" is considered anywhere between the L and H. The oil being at "H" is the top end of "Normal".

Theres not too many times i will say this, but this is incorrect. filling to H will never cause engine problems

brucelidat · 03-13-2012, 12:27 PM

So are 2011's pretty safe from this? I wasn't having any oil consumption problems before and haven't checked it in a while now.

kenchan · 03-13-2012, 12:29 PM

hey bruce- just check your oil at least once every 2wks when the engine is cold.

i found that the car eats oil when at the top dot, but does not if at just a hair above the 3/4 area. this was the same way on my G when new. after about 10k miles the consumption was gone and i filled all the way to the top and each time i checked the oil was near the top dot.
