Are the 4.10's more fuel efficient than 3.73's?

Wow...21.64 gal of gas where I live would cost $107.75. $4.98 gal in Palm Desert....Cali

Try $117 up here in Washington state. $5.60 gal avg. Word is, there's going to be a $.43/gal increase come Jan 1, 2023 due to an insane and idiotic 'carbon tax' our legislature passed this year.
'Had Enough? - Vote Republican !!' This is our motto here in solid blue country.

LOL, I hope you guys talking about fuel costs remember to vote here in a couple of weeks.....

$2.999 for 87 octane yesterday.

If voting changed anything, they’d make it illegal.

Here's the best mileage my EVIC's ever recorded. Was on a road trip from Washington state to Wyoming last month. I took this photo while coming thru the Rockies at St. Regis on I-90. Mostly I'm getting around low 15mpg. I chock this 21mpg up to being a fluke of EVIC. It was so out of the ordinary that I snapped the shot for the sake of posterity.

I don't know how tf you guys are getting that mileage, lol. Have a '22 Hemi with 4.10s and around 2.5k miles and my lifetime avg. is 11. Wtf?

As the former owner of two 6.4's, one with 4.10 and one 3.73, neither was fuel efficient. They were fun trucks though!

I dont pay for my fuel, so I drive it like I stole it most of the time....well, when Im not in gridlock traffic.

Out of curiosity, I once ran at 65 to see what I got for MPG, and I saw 19 on the display with the cylinder deactivation ******** disabled.
