Would you use 0W30 instead of 0W20?

If you're concerned run a high quality 0w20, like M1 0w20 EP. This is not a high performance engine, and where you're located you will benefit from the thinner oil, regardless if the 30 weight is 0w30, its still much thicker than an 0w20. I used kirkland dexos1g2 0w20 and the car runs fine here in SoCal. 0w20 is pretty standard now and full syn. It's not like 5w20 was born yesterday. I'm pretty sure the oiling system was changed with the switch to 0w20.

In what car? Both our vehicles have coolant/oil heat exchangers (common on most modern vehicles) and the oil gets up to temp right along with the coolant, which happens extremely quickly on the RAM and within about 10-15 minutes in the weather we have presently (cold) in the Jeep.
It's the same with my Chevy vehicles -- a maximum 15 minutes till full or nominal engine operating temperature in Alaska or Wisconsin in freezing or below freezing temps.

30 minutes? Maybe at -30 or -35 below zero...

Wow!

The oiling system was changed when the oil spec was switched from 5W-20 to 0W-20 ? I doubt that, why would it have to be changed ?

I got mixed up with the other gm 1.5. LFV. That one changed to 0w20 from 5w30 in 2018. I thought I read something about changes to the oil system or oil cooling.

I'm going through an internal debate with myself about this subject. I have a 2021 Jeep Gladiator in which 0w-20 is recommended for the 3.6L engine. If this was just a street driven car I would just use the 0w-20 and not worry about it.

But, this Jeep does go off-road in the Nevada desert and also hauls a small travel trailer. Oil temps can get pretty warm. I can't help but think the extra protection of a 0w-30 or 5w-30 synthetic would not be a bad thing.

I ran 5w-30 in my JLU Wrangler which had the same engine. I never noticed a down side to using it.

I wouldn't debate it too long. I'd run a good synthetic 0w30 or 5w30 and sleep well at night.

I just purchased a 2021 Gladiator and at the 1500 mile oil change 5w-30 went in it and will remain I’m it till I get rid of it. It rarely gets below freezing where I am.

I would absolutely use a 0W-30 instead of a 0W-20. The problem is that good 0W-30 oils are hard to find, and they will become even harder to find. SOPUS just pulled Pennzoil/Quaker State LX 0W-30 from the US market. Other 0W-30 are either expensive, hard to find, or expensive and don't have any certifications. Why torture yourself? There are plenty of decent 5W-30 options out there.
