I would advise you not to go that far between oil changes. These cars burn oil, and you never really know how much unless you do your own changes and keep track.
Maybe the older engine (VQ35DE) design did but Nissan clearly solved that with the HR engines. My car burns NO oil. I check it by the dipstick routinely too.

Nissan/Infiniti lists (2) service schedules (including oil changed), both based on conventional oil. One says 3750 miles and the other says 7500 miles.
Just to clarify, *I* won't go much beyond 5k miles myself but if I had to, I wouldn't worry.

Straight from Nissan's owner's manuals of G35/37/Q50/60
2013 and earlier all use conventional oil on an interval of 3750
2014-2016 use synthetic on an interval of 5000
2017+ use synthetic 0W-20 or 0W-30 on an interval of 10,000 miles or earlier if the information center says to change oil.
Nissan's software at the service center still says 7k for all models prior to 2014 though but I would definitely ignore it and go off the owner's manual data if you're sticking with the recommended fluids. The reason for the generational improvements and changes was the cryo DLC used in 2014 and further improvements to the DLC and micro-polishing in 2017 which allowed for the much lower oil viscosity. There's a lot of science and longevity testing that goes into the manufacturer's recommendations, they're not just made up by a low-level intern based on what "feels right" or what the rest of the industry is doing.
However it all applies to the AVERAGE vehicle, there are still improvements to be made and maintenance cost is a factor.
Car decided to cut off on me at the light while idling. Blah. Pulled the code and good old camshaft sensor. Have an extra in the shed from the last engine when I did the swap so 20 mins later sensor switched and we are good to go. Really been toying with the idea of painting my car carbon fiber hood included. Maybe a dark stealth grey?
These cars burn up so much oil that u always have to keep refilling.
Technically, your oil is always fresh
This, lol. I change it at 7-8k just to swap out the filter. I add 1/2 qt every 450 miles or so. Pretty sure I'd qualify for an engine replacement if my car was still under warranty.

I have the hard copy of the owner's manual as well as a downloaded PDF copy and it does not list change intervals. Maybe you mean the service and maintenance guide ? If so, this is what it says:
DETERMINING THE PROPER MAINTENANCE INTERVAL
Depending on your driving habits and local conditions, you should follow one of the three maintenance schedules listed below. Use these guidelines to determine which maintenance schedule to use:
PREMIUM MAINTENANCE
(Every 3,750 miles or 3 months, whichever comes first) Premium Maintenance is an Infiniti-recommended option that is suitable for all driving habits and local conditions. Infiniti developed Premium Maintenance for owners who want the ultimate in preventative maintenance. With Premium Maintenance, more maintenance items are regularly checked or replaced than with either Schedule 1 or Schedule 2 maintenance schedules. Using the Premium Maintenance schedule may optimize the performance, reliability, and resale value of your vehicle.
SCHEDULE 1 (Every 3,750 miles or 3 months, whichever comes first) Schedule 1 features the same 3,750-mile service intervals as Premium Maintenance; however,with Schedule 1 fewer maintenance items are regularly checked or replaced than with the Premium Maintenance schedule. Use Schedule 1 if you primarily operate your vehicle under any of these conditions:
Repeated short trips of less than 5 miles in normal temperatures or less than 10 miles in freezing temperatures
Stop-and-go traffic in hot weather or low- speed driving for long distances
Driving in dusty conditions or on rough, muddy, or salt-spread roads
Towing a trailer, or using a camper or car-top carrier
SCHEDULE 2 (Every 7,500 miles or 6 months, whichever comes first) Schedule 2 features 7,500-mile service intervals; with Schedule 2 fewer maintenance items are regularly checked or replaced than with Schedule1. Generally, Schedule 2 applies only to highway driving in temperate conditions. Use Schedule 2 only if you primarily operate your vehicle under conditions other than those listed in Schedule 1.
Neither the manual nor the maintenance guide makes any mention of conventional, synthetic, synthetic blend oils either. It only says the oil should meet API spec "SN".

You need to flip through the pages of the scheduled maintenance to the actual service intervals, that snippet was from the preface which describes what the schedule 1/2/premium maintenance is.
Also yes it does specify synthetic oil, it specifically calls out ESTER oil on the years where it is required to use synthetic.

Finally got my car from my kinda illegal hurricane storage spot in a parking garage. Luckily she was unmolested and was still classing up the joint. I missed that loud fat booty, but glad I moved her, had a large limb fall where I usually park.
I've seen the reference to "esther" based oils but I think it's in documentation for newer models. Even though it doesn't apply to my model year, I did Google what an esther-based oil was and there was even debate about that !
For 2008, here's the engine oil call-outs:
Engine oil with API Certification Mark*2
Viscosity SAE 5W-30
and
ENGINE OIL AND OIL FILTER RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade, quality, and viscosity engine oil to ensure satisfactory engine life and performance, see “CAPACITIES AND RECOMMENDED FUEL/LUBRICANTS” earlier in this section. INFINITI recommends the use of an energy conserving oil in order to improve fuel economy. Select only engine oils that meet the American Petroleum Institute (API) certification or International Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils have the API certification mark on the front of the container. Oils which do not have the specified quality label should not be used as they could cause engine
damage.
That's correct, in 2008 the recommended oil was still conventional on a 3750 interval.
When Nissan specifies ester oil they mean synthetic, I have no idea why they use the terminology "ester" instead of the more commonly understood "synthetic", perhaps because there's different types of synthetics (blend, ester, and full synthetic).

So they can sell a more expensive oil change at the dealer. Nissan is going to try and upsell me again today when I go in, lol.
The local Infiniti dealer was running a $40 oil change special not long ago. Includes the filter (some may suggest it's extra), tire rotation, and fluid checks as I recall. They mentioned using a synthetic-blend oil as well.
