In theory going with a thicker oil will help if your car consumes oil... But going with a 0W, would probably be worse because it will consume just as much if not more oil because the thin oil can move anywhere

Old school thinking, car uses 5W30, when it hits 100k, move to 10W30 or 10W40

Thats not all the way true... Nissan will only replace an engine if the oil level drops 10mm on the dipstick after 1500 miles... My engine consumes a little bit of oil, but not enough to get the engine replaced... 10w40 would be to thick for startup (cold starts) IMO, especially in colder climates like WA state. I would rather have better protection with a 0w or 5w..

0w40 is thinner at startup compared to 5w30 yes... but at operating range, the 0w40 would be thicker.

Isn't consuming and burning oil the same thing? Oil getting past the pistons rings and being consumed and or burnt off in the combustion chamber.

Exactly, your car probably burns oil...

And I know it's thicker at operating, but if the goal is to prevent oil from being consumed, 10W40 is a better choice

(But 0W40 puts less stress on the whole system at start-up, that's why I think a lot of people go with it)

Exactly. WA state is too cold to be using a 10w.

Burning/consuming oil is the same thing.

I'm pretty much set on changing out to Redline 0w-40 on my next change. After doing some research on this topic, tons of people in all kinds of different car forums swear by this weight oil.

It's funny how people swear by different oils. I thought German Castrol 0w30 was the shiz in my Tundra, but my last oil change was with 0w20 Mobil 1. The truck seems to like it better. The valvetrain quieted down, and it sounds like less of a diesel... Go figure.
