Best way to mitigate issues and reduce some of the consumption is to :

1, install the oil pan spacer
2. install a vented catch can
3. check oil atleast once every 2 weeks
4. do regular oil changes every 3000 to 3500 miles
Sadly none of the 4 actions you listed will reduce consumption. At the very best they will help to try to keep whatever consumption is happening from getting worse. But it will in the majority of the vehicles it's happening to.

My opinion on VQ motor oil consumption from worst to best.

VQ35DE rev up
VQ35DE
VQ30DE
VQ40DE
VQ25DE (almost non-existent)
VQ25HR (non-existent)
VQ35HR (almost non-existent)
VQ35DD (non-existent)
VQ37VHR (non-existent)

This is all assuming a low mile well maintained engine as they came from the factor (10k miles or so)r With 60k+ miles on the engine all bets are off and by 150k practically ALL engines burn oil to some degree.

Driving style is a massive factor in how much oil is ingested through the PCV.

I hear you, my G was my 31 mile (one way) commuter for the previous year and I checked the oil weekly. Unfortunately this new jobsite has a 1.2 mile very rough gravel/dirt road to get into the construction area and it's too rough to drive the G to work so... now it's just a weekend warrior, if this snow ever melts

But everything I have read while researching the G is that all of these engines use oil. Best way to mitigate issues and reduce some of the consumption is to :

1, install the oil pan spacer
2. install a vented catch can
3. check oil atleast once every 2 weeks
4. do regular oil changes every 3000 to 3500 miles

PRO TIP: stay away from using oil additives meant to slow it down.. like the STP stuff etc. Just use a really good synthetic oil like Castrol I think was rated the best for these engines (looking at metal deposits PPM) it had the lowest amount Mobil 1 was the worst.. but the oil additives just create havic in the engine could increase sludge build up, mess with the oil pump etc..
I don't agree with the 'use a good quality synthetic oil' bit. The internet has done a heck of a job of making conventional oil look like poison for your engine,

I can't speak for the rev-up but the owners manual in my DE explicitly says to use mineral based oils. Why so many people insist on using synthetic on an engine design dating near 20 years baffles me. If Infiniti says 'mineral oil' why try and outsmart them? Inconsistent molecules from mineral oils can be beneficial on engines without the tighter sealing and lower quality rings. Even my local dealer does not recommenced synthetic in older models despite the extra sale involved. My car has used nothing but dealer bulk oil, Mobil Super 1000 in my case, and I have zero OC in my once a year oil change. Then again, I only do 3000km/year and have 65,000km on it but I have yet to add a drop of oil since I bought the car. Perhaps some users may see less OC by going conventional. Just a thought.

I noticed a slight decrease in OC (~1/2 qt every 3000k) when using conventional over synthetic but what's more important is using the conventional forces me to change the oil more often which is important given I refuse to use Nissan's shitty dipstick since I don't trust it

This is misinformation, it was from an attempt to collect and compile Blackstone Labs oil analysis data but the sample sizes were too few, in many cases there was only a SINGLE set of data for various oil brands and they were all on different motors of varying wear and abuse.

If Joe Dude runs the snot out of his car every day on a worn motor and turns in his oil analysis using the best oil ever made it will still be full of metal.

If Your Grandma puts around leisurely on a well maintained motor and only runs conventional dino poo oil her report will show no metal deposits.

Does this mean her oil is better? Or that his is worse?

No, it means the sample sizes are too small.
