The oil temp gauge is good.

oil temp gauge is good.

The water temp gauge is hard to read at a glance - just a single lit led in a row of 16 or so. You can add a scanguage if you like keeping track of stuff

I really wish we had an oil pressure gauge.

I recommend the AE Performance oil cooler. It's a bit more cost-wise, but it actually works as promised and has some excellent key features.

As stated above, the oil temp gauge works well. It's easily read and has enough hashes to be more granular with the temperature readings. The others - all suck. WTF is up with the water temp gauge? That is the most useless POS ever. And I do miss having an oil pressure gauge...temps are nice, but if there is no pressure....ummmmmmmmmmmm.

So do you guys change the oil before AND after any track days, or just before or just after?

The debate is not whether or not 220 is within operating range, but whether or not it will be sufficient for protection after 7500 miles. The answer is no.

Present your data to backup your claim. Your outdated chart proves nothing.

A quick search for the test method to certify API SM (dino or synthetic) oil is as follows:

A key new test for GF-4, which is also required for API SM, is the Sequence IIIG, which involves running a 3.8 L (232 in³), GM 3.8 L V-6 at 125 hp (93 kW), 3,600 rpm, and 150 °C (300 °F) oil temperature for 100 hours. These are much more severe conditions than any API-specified oil was designed for: cars which typically push their oil temperature consistently above 100 °C (212 °F) are most turbocharged engines, along with most engines of European or Japanese origin, particularly small capacity, high power output.
The IIIG test is about 50% more difficult[10] than the previous IIIF test, used in GF-3 and API SL oils. Engine oils bearing the API starburst symbol since 2005 are ILSAC GF-4 compliant."

So, for all you guys who think oil temps are an issue you need not worry unless you run your engine all day long well above 260F. I submit that Nissan designed their engine to go into limp mode above 280F to prevent engine damage based on the newest oil standard quoted above. In another ten years it will probably even higher.

that is certainly not outdated. clearly you are misinformed.

You obviously never track your vehicle. I am not saying that I do, but I am good friends with quite a few who do. Having just come from a GT-R, I can tell you that temps above 240-260 for a track day; the oil is changed. I even changed mine every 1500 miles as I would see temperatures of 240+ sustained on mountain runs. Keep in mind that the GT-R is designed for track usage...well, moreso than the 370.

If you want to drive 7500 miles at higher temps between oil changes, more power to you. Me, i will opt to protect my engine...especially since it will be twin turbo'ed soon. Massive AE Performance oil cooler will be first modification.

We're discussing routine oil changes for normal vehicle operation - not tracking. Obviously you can't digest what the current API SM specification standard is. This is 2010 not 1970. There have been technological advances not only in engine design but also in lubricants. If you want to resist change that's fine. But don't come in here espousing that oil if not changed prior to 7500 miles will cause pre-mature failure. Because that is what you are insinuating which is BS. So, for you, I'll return the same courtesy

Straw-man arguments are your specialty, I see. I was extrapolating track usage temperatures to what we see in the 370Z under routine or spirited driving. Again, if you wish to reach temps of 240-260 under spirited driving and 220+ under normal conditions and change your oil every 7500 miles, enjoy! You are obviously misled if you believe this will not cause premature failure.

No they aren't. You had nothing of substance nor fact to refute. Anyway, if you'd like to put up some facts I'd like to read them. Extrapolating with track friends doesn't do it here.

And no, I don't track my cars. But I am quite familiar with multi-million dollar naval propulsion systems if that counts toward knowing something about lubrication.

Ok.. bottom line: you are pushing the limit and ppl who get changes every 2k miles are making sure their 40k investment runs in 10 years... if your wallet can afford changes every 1k miles - you should do it... whats 80 bucks every couple months to have peace of mind? lets please stop this personal opinion rampage that this thread seems to be experiencing

Zguy · 02-10-2010, 01:31 PM

I change mine every 3k or 3 months which ever comes first.... I dont risk it with oil especially since I drive the hell out of my car....

PapoZalsa · 02-09-2010, 09:35 PM

I won't go over 4,000 miles with synthetic, so non synthectic 3,000 max if so.

m4a1mustang · 02-10-2010, 06:56 AM

I use Redline and am not comfortable taking it too far beyond 4k-4.5k miles under regular driving conditions. It may very well be good beyond that (and probably is), but at 4k I'd much rather replace the dirty stuff with clean and go on with it.
