Gas Mileage

What was your speed?

If you divide the miles driven by the time, he averaged 57 MPH.

That sounds about right. Speed limit on the NE extension is 70 mph and then there's areas of 13 going through DE and MD that are down at like 40 mph with an unnecessary number of traffic lights.

Had this in "What did you do to your Ram today",
Put in 91 octane 100% gasoline, $4.42/gallon, 12.05 gallons with 89 octane in the tank. Did it to satisfy some curiosity, no access to 100% gasoline in my local. Ran from Schenectady to southern end of NYC (NY Thruway, NJ TPK, NJ Rt 17 + others) doing speed limit for the most part, some passing at higher speeds, majority highway, minimal congestion, outside temp in the low 60s. MPG stated 25.7, been driving locally today and went to 25.3 last I looked. Have not filled up so so I don't know hand calculation. Initial mpg was reading 26+. Don't believe there was a tail wind as mpg going to Schenectady was pretty good. Previous best was 24+ mpg, straight and flat I95.
Update - Hand Calculation
Did some more highway, plus city and got stuck on the Garden State Parkway do to an accident so lost some mpg on GSP, total miles 312.3, meter read 23.3.
Final hand calculation was 23.47 (90 octane with a 5.4% alcohol content)
Best mpg all time is 24.31 on I95 and 24.27 (?).
Can the Hemi get 25+ with all highway? I think it can with the right conditions.

I've pulled off 23-24 several times, just cruising back roads under 60mph. I'd be all kinds of happy if it got that at 75!

wow, you guys are killing it, LOL.
24 e torque, 321 s, 1600 miles. Averaging 19-20 per tank on regular fuel. Mixed driving but in a nice rural area for the most part.
