These are actual screen shots, where the mileage is happening at a minimum altitude of about a mile, and a maximum that tops just over 10,000 feet, with a lot above 8,000.
No special brands of gas, Conoco, Shell, whatever at 87 pump rating used.
Not exactly a featherfoot [its a hemi for chrissake] but do have the ability to maintain pretty constant speeds when possible.
A tiny bit of freeway driving, but mostly urban where the speed limits range from 25 to 50 and a goodly number of stoplights, plus a LOT of climbing steep hills and making up the resulting 4 mpg on the return path.
Overall miles is 1654, at average speed of 27.3 mph and 18.7 mpg since it left the depot down by Castle Rock on a freeway trip to Longmont.
Reset the trip odo at 795 miles to see how break-in might be affecting mpg over the same driving patterns--it seems to help even though I refrained from sticking my foot in it or trying sport mode until after about 600 miles had passed.
After break in, 859.4 miles at an average speed of 30.154, getting 19.1 mpg
Rarely stay down at speed limits, but haven't had it over about 90 yet either. Don't rip out of lights or signs, but do hit the gas once it has shifted up a gear or two...
