MT Oil consumption failure

billydsz

I don't even know why I bothered clicking on this post.

My engine failed beore 6000 kM. They did the short block replacement. They said there was some problems in the early models, but the new block had a fix for it. Well I checked the oil and after 3000 Km it needed more. So I don't think there was a "fix". Interesting to see the "vacume" theory. In my case I doubt that happens very often.

How much more is the question. OP was using 6qt every 2900 miles. That is the very definition of excessive. 1- 1.5qt every 3000 miles would not bother me in the least.

Aren't the Cats considered a Emission part? If so then the warranty is 8 years 80k.

Specified major emission control components
are covered for the first 8 years or 80,000 miles.

You are correct, thanks for the correction - used to be 3/50,000, but was increased to 8/80,000.

Here is the verbiage straight from the EPA notice that you posted:

There are three specified major emission control components,
covered for the first 8 years or 80,000 miles of vehicle use on 1995
and newer vehicles:

* Catalytic converters.

* The electronic emissions control unit or computer (ECU).

* The onboard emissions diagnostic device or computer (OBD).

I've fixed my post.

Op,
I feel your pain...
It's sad to hear that you are going through this mess and I hope everything works out with the new motor.

If I may ask, what year is your 370z?
-09?

Any 2010's with similar problems?

I think the Nissan TSB covering new short blocks for oil consumption includes 370Zs made through May of 2010.

Please tell me where I can find the TSB on oil consumption, my 09 is in the shop as we speak. It went into limp mode the other morning and the first thing I checked was the oil and it was 3 quarts low and I only have 2500 miles on it. I did mention this to the tech at Nissan and he also felt that it was excessive. I will find out more tomorrow.

Here you go.

TSB: 2009-2010 Nissan 370Z: Engine Oil Level Is Low

Mt Tam I am

I never went into limp mode, but 1.5 quarts in 1500 is the test. A little more perhaps during break in. I wish you luck, but it sounds excessive to me too.

Were you keeping your oil "Topped Off" ?

CARBs states have longer warranty, I don't think Texas is a CARB state

TreeSemdyZee

Yeah. Since CARB stands for California Air Resources Board

Here are the gory details:

• Federal Emissions Warranty – Under the Federal Emissions Warranty, all emissions related parts are covered for 2 years or 24,000 miles*, with the catalytic converter, onboard emissions diagnostic device or computer (OBD), and engine control unit (the ECU or computer) covered for 8 years or 80,000 miles*. These Federal Emissions Warranty provisions cover light-duty vehicles up to 8500 pounds Gross Vehicle Weight Rating (GVWR).

• California Emissions Warranty – Under the California Emissions Warranty, vehicles certified for sale in California, and those states (e.g., Vermont) that have adopted California Emissions Standards by law, have additional coverage beyond that required under Federal law. Under the California Emissions Warranty, all emissions related parts are covered for 3 years or 50,000 miles*, and a vehicle-specific list of more expensive emissions related parts is covered for 7 years or 70,000 miles*. In addition, the 8 year or 80,000 mile* coverage for the catalytic converter, onboard emissions diagnostic device, and engine control unit required by Federal law also applies. Also, some 2003 and later models, certified as California Partial Zero Emission Vehicles (PZEV), have 15 year or 150,000 mile* emissions warranties essentially covering any component that causes the Check Engine Light to illuminate. These California Emissions Warranty provisions cover vehicles up to 14,000 pounds GVWR.

*Whichever comes first

However, be aware that some manufacturers have voluntarily extended their emissions control warranties for certain models and certain parts to 14- or 15-years and 150,000 miles (whichever comes first).

OP, how did you break in your last two engines? When did you perform your oil changes and what oil did you use?
