I have some local driving to do, and another test run on Saturday on flatter ground. I will "fill to the click" when I get on the highway and repeat as suggested.
Running around in town I only get about 17 MPG at best.

I calibrated the ABS at 31.2" for these particular tires. This resulted in
60 MPH = 1680
65 MPH = 1820
The smarty touch allows calibration in 0.05" increments, approximately 0.16%
I set an initial guesstimate and run 20 miles of mileposts and do some math, pull over and make a correction. That is usually all it takes.

I am picking up some 2011 alloy wheels. These are the lightest factory Ram wheels at ~20 pounds. They have the stock Michelins on them, probably calibrate at 31.5" or so.
The latest LTX are called Defenders now. They are 31.6" according to the manufacturer.


Yesterday, The conditions were far from ideal. I was stuck at 20 MPH all the way up White pass behind some trucks, and the overhead dropped down to 14 MPG. Ouch.

Speaking of the overhead display, it is MUCH more accurate with fresh injectors. Before, it was quite optimistic. I figure it like this:

The computer only knows duration and pressure to figure out MPG. I think the old slobbery nozzles put out a whole lot more fuel in a given duration+ pressure than the new nozzles. The other day I ran I-5 up to Lake Stevens and back, and got 23.4 MPG. The overhead was at 23.2 for almost the whole trip.
