I am currently using Kirkland's oil and no issues whatsoever.
It’s more of a lifted Camry than anythingProb for the best... I mean you have a Lexus..
I’m guessing different anti wear add packs maybe.Someone educate me on this subject, because I've heard it before. How does an engine run "rougher" on one brand of oil vs another?. The dynamics of an ICE aren't changed by a lubricant....at least as I understand it.
Serious question. Not stirring things up or being a smart a$$.
It could be in your head, or it could just be that your Xterra sounds rougher on that oil as compared to others. If the sound bothers you, dump the oil and go to a cool-sounding one. Chances are your engine won't notice the difference, but you will. And it seems that's important to you.Who knows maybe it's all in my head...

I guess it's something I've never really noticed in any of my vehicles.This is my observation so purely subjective here.. I notice the engine seems to rev easier throughout the RPM band with less effort, is the best way to describe it. Just like you can tell when engine oil is getting near it's end of life vs new...

Possibly a what? Maybe on startup but once it's running? C'mon manPossibly an oil filter issue?
Go get an empty QSUD (Smooth and quiet) bottle and pour the Kirkland oil in it first. Then pour it into th car. That will quiet it down.
I think much like the ass dyno people use (“ohh yeah I definitely feel about 60 horsepower more after that cold air intake install”) it’s all psychological. Packaging looks slick and cool and they mentally feel like it’s smoother. Every oil seems to have no shortage of either overwhelmingly positive or negative oil review either says my engine runs smoother or my engine runs like ****.Someone educate me on this subject, because I've heard it before.

Buddy of mine has recently started using the Supertech variant 5w30 synthetic in his 2002 Xterra 3.3 NA and says it is quieter than when he was using Mobil 1 5W30 Syn. Interesting that you are having the opposite experience.
