For the curious:
Preface: Vehicle settings/configurations, driving style (stop/go lead foot or not), driving terrain (flat ground or hills), cargo/load, weather and dozens of other factors come into play for fuel consumption, so as they say, your mileage may vary. Here are my findings so far.
Vehicle: Stock AWD RTL
Fuel: Costco regular 87 octane
Drive setting: Normal, ECO mode OFF (never use it, truck is already “sluggish” compared to smaller lighter sportier cars in non-comparable segments)
Drive area: Pacific Northwest, greater Seattle metro area, mostly freeway/highway that have mild elevation changes, some towing under 1500lbs, primary route is to and from a 500 to 0 to 500 foot elevation over a ~20 span. (Elevation estimates via
veloroutes.org - cycling route maps with elevation profiles)
Tracking started at: 302 miles (post first tank of gas)
Total fuel in calculations: 138.97 gallons
Total mileage in calculations: 3182 miles
Average MPG from above data: 22.9
I like to fill when there is still 100 or more miles of range, as I don't want to be "that guy" who ends up on empty on a commute rush hour traffic jam...
Two round trip “long distance” freeway trips, with total elevation gain/loss of 2702ft round trip
563 miles, 24.41 MPG
579 miles, 24.98 MPG
From available data on 8 fill ups out of 12
Computer MPG - Hand calculated MPG (Average/Min/Max): 0.88/0.76/1.43 - computer over estimates economy
