I would rather experiment while the engine is under warranty, that way if it goes south, the manufacture can fix it instead of me.
This is only the 4th year for the 2014 & newer 0w20 5.3L, so who knows if they will become oil burners in the future.
The average age of these engines and the 0W20 6.2L is 2 years and around 35k miles.
I looked at a 2015 SLT 6.2L max trailer yesterday with 32K miles (52K km) on it.
Summit white,153" wb, but too many bells 'n whistles I'd rather not pay for, and a few options I would rather have instead.
Asking price was $34k USD equivalent in Canadian Tire money.
I'd want what I think is best while under warranty and after it.......... But the safer bet on Bitog is to say use what the mfg. specs, change it when the OLM says so, or refer to the owners manual. That keeps you out of trouble. No comment on what's best a 20 or a 30 grade, thicker, thinner, etc. I made my choice with my new Rubicon while under warranty....
I wasn't going to wait.
