Have anyone ever check their MPG difference of driving at 75 mph vs 60/65 mph ?? V6 Pentastar or Hemi


I have a 2015 SLT Quad Cab Pentastar V6 845 RE 8 speed transmission 3:21 gears
In my case I do not really see much if any difference !
I did a 5 hr drive at 60 and man that was hard to do lol
Same ride doing 70/75 and basically no difference
Weird question but I am retired ,old lol

Mine will change 1+ MPG.

I may see the 1mpg difference but that would be on the high side lol. Not enough for me to slow down while on a long trip lol

Over time, I've found that my best MPG is around 2200 rpms, regardless of speed. To that end, I usually limit the trans to whatever gear keeps me there with my 3.6 and 3.92.

I try and keep mine under 2k rpm range or less

I used to run that way due to decades of old conventional wisdom. When I realized that the Pentastar "liked" to run higher rpms than I was used to, the MPG ticked up a bit.
