you mean weight? its 5w30 for redline same with the nissan ester oil

Of course 5W-30 is just the default recommendation (and not a bad one). You can (and perhaps should in some cases, but do your homework first) pick other weights to protect the engine better depending on your ambient conditions and driving style. Going thinner (lower numbers) protects you a little better from cold-start wear, so it's a good idea in very cold weather, or if you're doing lots of engine starts per mile (many short trips turning the car off between), whereas going thicker will maintain viscosity at high engine oil temps better for when you're racing. It's all a tradeoff, there's no universal answer that's best for all scenarios.

I changed over to Pennzoil Platinum 5W30 and it seems like the temps have been reduced. From what I can tell the Nissan Ester Oil is possibly based on the Pennzoil but I haven't found conformation of that yet.

I have seen other threads floating around on this issue, but not with 59 pages since the thread opened in March.

This brings back bad memories of my 1.5 yrs on a thread over on my350 with the oil consumption (OC) issue with the 2006 350z rev-up engine. Some may know me on that thread as ZeeForce. What a drawn out miserable ordeal with Nissan North Amercia (NNA).

Here we go again, I sold both the 05 and 06 350Z's for two of the 370Z's.

Got some reading to catch up on this thread. I read the first ten post and the OP has the same thoughts I did with the OC on the rev-ups - its the principle.

One word to Nissan North America always gets them to sit up and listen and the word is "FRAUD".

In the next few weeks I am having an oil cooler (third party) installed and will jion in here and contribute to this thread based on my previous experience with NNA - Goliath.

Cheers

You and I spent way more thime in that thread than I am sure we wanted too :tiphat:

John

You got that right!

I am digging this 370Z, even with this oil temp issue.

Just as a comparison I finally got around to installing my Oil and water temp gauges. Well it does seem the HR is a cooler motor.

It was 102 degree's out, and the car's oil temp was reading a steady 190 degree's. I got it as high as 205 when I shifted to 4th at 70 and left it there for a little bit. Water stayed around 180. Will have to see what it does on the track now. :)

Engine blew out
 

there is deff something wrong with the 370z oil temps my engine had actually blow out and one of the reasons is because the temp reachers to high nissan has given me a new engine and its not the same ... I am fighting to get my money back anybody else who has had this problem yet???

You're good with english. Please post pics and records pdf'd please. I don't buy your story with this being your first post.

What?

Scan your repair order and post it up. I want to see the part number for the new engine.

:icon17: So, you're saying Nissan installed a different engine other than the 3.7L in your 370Z? Perhaps it's the Twin Turbo GTR engine? or does the engine look like this? :bowrofl:
