Knowledgable responses would be appreciated.

You won't be able to do much "spirited driving" with that temp that high before goin into limp mode. Oil doesn't effect the tempature of the engine as far as going from nissan's oil to mobil 1. I thought that same thing but the Z's come with a ester based oil from factory and mobil one claims to have ester in there oil. If you research you will find that Mobil 1 full synthetic is a ISLAG GF-5 and Nissan runs a ISLAC GF-6.

actual ECU controlled "limp mode" doesn't kick in until around 270-280. I've had plenty of spirited 10-15 miles drives where I started at 220 and ended at 240 or so. I've come nowhere close to limp mode and I live in Texas.

That said, some people (myself included) have noticed at times some sluggish low RPM response when the oil is > 220. I don't know what that is, but it isn't limp mode.

Hey Z QUALITY......interesting note you wrote about voiding warranties. You "indicated" that a full synthetic is required to not void the Nissan warranty, however, my Nissan dealer's normal oil change for my new Z is regular, non-synthetic oil. I have free oil changes for life as part of my purchase, but paid an upgrade difference for the Mobil 1. My dealer didn't even offer the Nissan, ester-based, synthetic oil everyone talks about. My dealer/service manager thought my whole conversation about oil was pretty silly.

Not to be a stickler ....Ok I'm being a stickler ... but Z Quality never "indicated" that synthetic is required for warranty. He said if you use synthetic, you won't void your warranty which is true -- (assuming the synthetic meets the viscosity and other requirements outlined in the warranty document). You are also right that any oil regular or synthetic will not void the warranty as long as it meets their specifications.

That is because your car is retarding the timing to make the car sluggish. This was brought up in another thread on this site. It took me less than 2 minutes to get from 235-260 doing some canyon carving in the high deserts here in cali. A.T. was 103 and when i got into palm springs it was 116. I was able to do about 70seconds worth of wide open throttle going up this canyon road and it shot up to 260 in no time. I had to baby it for the next 20 minutes to get her to cool down. I too did notice it getting sluggish.

It seems that all of our cars have unique quirks or characteristics. My car heats up to 220 fast, but is slow to rise to higher levels. I've certainly never hit 260. Perhaps the 'verts -- being less aerodynamic -- get more air running through them. Also, temps were not hitting 116 -- though they were pretty close this summer ...

Also people mean different things by "spirited driving" I've never kept my revs wound up to 7k for 15 minutes straight ... more like 4-5k spurts on the twisties during my Lime Creek Drive runs

Another question....5W30 is the specified oil for the Z, but I keep reading about the advantages of other viscositys (sp?) such as Mobil 1's 0W40.....what do you guys think about this?

You need to figure out what you are going to be doing with your car and then pick the "correct" oil for that application, ie. track whore only car, dd, semi dd and part time HPDE etc.

When in doubt, just run the manufacturer's suggested viscosity, ie. 5w30.

FYI, I run mobil 1 0w40.

mobil 0w-40 if you intend on keeping it forever; otherwise save your money.

If you wouldn't mind sharing some info on temps. What are you getting in winter and summer with both extreme temperatures?
