Why 0/20 Oil for 2023 5.7

[Mountain Whiskey]

Wait, the compression changed for 2023? When did this happen?

It didn't. Still 10.5:1. The Pentastar is 11.3:1.

My '22 Limited requires 0W-20

2022 and up will explode if anything but 0w20 is used.

It is quite true that a lot of the changes vehicle manufacturers make have very small effects on the fuel efficiency of the vehicle. But that's just how things work. Small gains made from year to year make a large difference in a few years. If small incremental gains are not accepted and used then no changes will ever be made. If Ram didn't make changes that actually only make small gains in fuel efficiency then soon a major change would have to be made to make up the difference. I for one would much rather see small changes year to year rather than a large untested change every 5 years. If it weren't for small changes year to year we would still be driving 1960 trucks. You may want that, but I don't. Those trucks in the 1960s had one thing going for them. They cost less than $2000. But then my parent's total income was less than $4000 per year.
