Gas Mileage Figures from July 16th, 2009 to August 5th, 2009 on The Dodge Dakota with Aerocap (Mostly) on and one trip with it off.
The image shows the Average Fuel Efficency per Tank of Gas at refueling time. This includes any and all construction events over a course of 300 - over 600 Kms per tank, and of course hills, dips, trucks (Semi's), and other traffic issues. Also things like - stops for eating, detouring to a Berry Farm for Blueberries, and overnight sleeps, etc.
It should also be noted that the box was pretty filled with Camping Gear - Air Bed, Tent, Extra Camping Gear, Clothing, Booster Battery, Suitcases, etc.
The Chart shows that the fuel efficiency values varied more with the short Trip up to the Barrie Area with the Cap Off, than they did on the whole trip through Windsor, Detroit, on to Chicago, and up to Oshkosh with a return the same way.
The Best Mileage was from the Pilot Travel Center in Michigan, to Toronto and then up the 404 to Richmond Hill, Ontario at 9.52 Litres per 100 Kms (LHK)!
The Figures for the leg from Benton Harbour to Oshkosh would likely have been lower as an all Highway travel figure, but it included about 4 days of camping, and driving back and forth about 10 minutes to the Travel Plaza for Breakfast, and again for Supper each day. Since the city performance is more weight related than aerodynamics, this skewed the figures lower than they would have been if I filled up at the travel plaza on arriving in Oshkosh on the 28th of July. Still they managed to be at 10.96 LHK for that run.
The Generally worst leg, for some reason, was from Windsor Sunoco, trough Detroit (Parked at the Wayne County Airport for a week) and on to Benton Harbour, Michigan, at 12.29 LHK! Whereas, the leg from the Barrie Area on the weekend of the 18th of July, to Toronto was 10.70 LHK, and the leg from Oshkosh back to the Pilot Travel Center, in Battle Creek, Michigan got 10.74 LHK.
The Second Best Efficiency was from Toronto to Windsor with 10.35 LHK as the result.
