4.10 Gearing Daily mpg not towing?

[chas0218]

Yeah, but the cost per mile was roughly the same. I tracked it for a year between 87, 89, and ethanol free. Maybe my 3mpg was off, but not much. Range does increase.

Cost wouldn't bother me if I didn't have to make as many stops on a long trip.

Did the same trip except with between 1500 & 1800 pounds.

This time I filled up right before starting and stopping and made 19.3 hand calculated where the dash said 20.1.

On the way there it got up to 21.7.

I find that very hard to believe with a gasser unless you didnt get over 50mph

Most of this trip was 60 MPH like this picture shows.

The trip is about 120 miles.

Was it all highway? And are you a gasser? This seems on par with diesel numbers.

Anyone see any improvement of running higher octane and better towing MPG?

I have a 6.4 Hemi with 4.10 axle ratio.

6.4 with 4.10's and 37s, i can get down to 13.5/100KM on long highway trips (mostly flat out here).

'21 Laramie CCSB 6.4 with 4.10 and still running stock tires. I'm getting 13-14 overall. 15-16 on long highway drives and I drive 70-80 most of the time, but factor in some in-town on either end of the trip and it will be back down under 15. I've seen no difference with 89 vs. 87. If I idle more than usual, get into the throttle more than usual, it will knock 1 mpg or a bit more off the average, doesn't take much.

Doing hand calculating the dash mpg indicator is always about 1 mpg higher than by hand. The always optimistic electronics .
