You can simply go by the oil life monitor - it tracks all of that stuff, proven by Lake Speed Jr. and is more accurate than you could ever be.

This is yet another thread beating a whole herd of dead horses until even the coyotes won't eat on them.
Papa ... we're baying at the moon. No one listens. But they think they are entertaining themselves.

Yeah, they seem to think they have a new idea, a better idea, or a life hack.............

But I just watched Nissan run the 3.8l at redline for 100 hours straight glowing red and didn't fail.
I have driven one of the newer Nissan Frontiers with that 3.8L and coupled with the 9 speed licensed MB copy built transmission, it is a pretty impressive drivetrain. Way smoother delivery.

Do you like it? Thinking about getting one to add to the stable for my daily.
I do like it , it does have more power as it is in stock set up it does pull nicely ,I notice it shifts about 2100rpm from gear to gear during relaxed driving. Redline is 7000. However the tires are much smaller than my 35's and the truck averages 17.6 which is what I get in usually 2 lane backroad driving. It rides really smooth with the IFS front end .
I think the nicest feature is the Tow mode selection.
The worst obviously ESS
2nd worse traffic lane warning ( I despise that because there are 1.57million sharp curves in WV and if ya get next to the line it beeps or vibrates the wheel.) I turn it off when I get in it .
Heated seats and steering wheel like our Jeeps and power seat is very nice. Wider than the Gladiator that I have . It has ample room for a guy my size 6'5" 215.

Being new to this forum I find it pretty toxic with a bunch of hateful people in here it must be exhausting being so angry all the time. I’ll bow out.
Oil viscosity and differential gearing are polarizing topics here and elsewhere. It is kind of pointless to argue, no one is going to change anyone else's mind, but for some reason we all keep doing it.

And if you hadn't used it - you'd likely be in the exact same situation. Nothing you add can "stabilize oil". I guess I'm surprised people still buy that stuff.............
You're correct that you can't "stabilize oil" but perhaps others here are thinking about a product to add additional viscosity to the oil. This is very possible. As you know, manufacturers fractionate the crude petroleum to get dozens of different "fractions" with various viscosities.

I think some here want to have a much more viscous additive or lubricant in general for their engines. Something like, a term that most would know, tar. Higher mileage engines may benefit from not having so much of that slippery oil stuff to deal with.

And it would make "oil" changes a thing of the past. Instead of using a funnel and possibly spilling the messy oil on the garage floor, you could simply do the "oil" changes with a couple gallon buckets of the "stuff" and use a putty knife to fill it up.

And you wonder why people (i.e., those who disagree with you) don't listen to you? Has denigrating people on the other side of a debate ever swayed anyone to your side?

Oh, and a caulk or grease gun would be easier.

It's hardly a debate when people who know nothing about oil or engines, and most have never seen the I side of one, come in with junk from Uncle bubba's buddy who one changes his oil and the thing still ran tells them. You try to give them facts, but they know better because the more something is read in the internet, the more true it must be. When people argue with subject matter experts, or tour some YouTube video told them thicker is better and the proof is their engine still runs, LOL,.....

But...but ..but, GM,.......yeah, sure

So far what I recall the arguments for and against 0w20 are

For 0w20:
  1. Owners manual says to use it
  2. Belief that the engineers are smarter than all of us and they were the ones that decided 0w20 is the best oil for engine lubrication and longevity, that it was not a compromise between longevity and fuel mileage, it is simply the absolute best for longevity.
  3. Lake Speed Jr explained how oil works. If you believe # 2 then you want to use what the manufacturer calls for, 0w20.
For 5W30 (or other):
  1. Anecdotal reports of it being quieter at startup
  2. Belief (with supporting sources that one may or may not believe) that 0w20 is for fuel mileage, not the optimum for lubrication and longevity. In other words, the engineers had to compromise.
  3. Lake Speed Jr explained how oil works. If you believe #2 then you want something more viscous than 0w20.
Neither side is supported by cold hard facts.

Please, there is a huge chasm between denigrating a person and questioning (or sometimes having a little fun) with their ideas or beliefs in a certain product or products.

Example: Fact: My 98 year old aunt passed away recently. She drank red wine with the best of them. She would do at least a bottle or more every day, until she was about 97 and the assisted living place took it away from her because she was spilling too much and it was staining some of the floors (she didn't like white wine, for whatever reason).

So I think most would agree that her case means nothing regarding a recommended use of alcohol, although she lived a long and wonderful life, much longer than most.

From a scientific standpoint (or in the our discussion, the manufacturers standpoint), there have been tests, historical data, blah blah blah, about what works best. Some may disagree, some know more. I could look at my aunt's case and say having 5 or 6 drinks every day will help you live to nearly 100.

Take it for what my opinion on that is worth ... very little, if nothing at all.

Like George Burns smoking cigars like a chimney and living to 100. If drinking gets you to 100 and smoking gets you to 100, I'll do both and live to 200.

There are examples of PUG engines lasting several 100K miles on 0w20 and others failing at less than 50K. Same probably is (or will be) true for 5w30 but the population of engines running it is much much smaller so there are few data points to be had and probably never will be enough to draw any conclusions. 0w20 vs 5w30 may have no effect on longevity whatsoever. My personal belief is everything but the valvetrain is perfectly fine with 0w20 but the valvetrain would do better with something more viscous to counteract a materials/manufacturing/design problem.
