I use engine breaking for shorter coast downs to lights, and for long coasts i put it in nuetral even with an auto transmission. Its oppurtunities to coast that really boosts mileage. For one 2 mile stretch of road with moderate traffic load, a shallow down hill, and the reducing speed limit into town i had the f150 in nuetral for the entire 2 miles. 99mpg+. Final speed limit was 35 mph up to a red light which i tapped on the brakes from just under 30mph.

Doing similar(coasting) in my own 4 cylinder manual transmission truck with a scanguage, 70mph is 300mpg, 60mph is 240mpg, 50mph is 200mpg, 40mph is 160mpg. The scangauge has been tuned to my truck for 1 to 2 % accuracy tank to tank.

Find the chances to coast and use them. This being said, i dont turn the engine off like some more extreme hypermilers. Pulse and glide doesnt work at highway speeds for pickups well either, or i would do that(poor drag coefficient).

I just reread your post about you using cruise, i dont. My foot gives better mpg than any cruise control I've tried. The cruise will want to shift going uphill to maintain speed, with my foot i let myself slow down to keep it in overdrive.

Even 8% off on 30 mpg puts it over 27mpg. I cant do hand calculation of mpg because i get the use of the vehicle for the trip only, be it 50 miles or 300. The other drivers mpg on the read out averages about 16 for the v8, and 18 to 20 for the v6 ecoboosts that i have gotten into. They cant keep thier foot off the gas.
