2024 Ram 1500 w/ 5.7L engine requiring 0w-20

For my typical daily driving (not lab controlled!), I find zero meaningful difference in MPG between 20, 30 or 40 grade. May be the way the Hemi is engineered.

Exactly my point. Same goes for protection between API 20s and 30s. You're more likely to see a difference when bumping HTHS to 3.5 (many Euro oils)

0W-20 is just fine for the HEMI, it's spec'd a 5W-20 forever in the 5.7L, though the 6.4L calls for a 0W-40. Unless you are going to be beating on it, the 0W-20 is a perfectly suitable choice.

Does yours have the factory oil heat exchanger? If so, oil temps should stay pretty steady.

Had to moderate this waste of time, far too many times.
