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.
