EcoBoost MPG Test @ 70mph
#21
The best MPG i got was the first 400 mile stretch, through some rather steep hills and slopes with a slight tail wind, the best i have ever gotten at this range, just over 24mpg, with average speed around 70mph(first half at 65 and 2nd half at 75 w/ cruise ctrl). over the remaining month of the trip it slowly dwindled down to the 20mpg area. Love this truck, it drives smooth, no hesitation at all towing a 4,000lb boat.
