I know, so many mpg threads. Maybe an auto, but dont think I've seen a 6spd posted this high. 1000 mi trip. Just drove smooth & overgeared where possible. No magic add-ons. Kept it speed limit 65 on interstate, most trip was over the mtns of VT & NH on state/county hwys @ 50-65, few stops & towns.
410 mi/ 17.8 Gal= 23 mpg w/ moderate load (gas light @ 398) on the way out. Around the mtns (some 4wd, off-road) and way back tanks were 21 mpg with A/C on and 500cc Enduro moto in bed.
