Stock 4runner. I use the Scangauge II to monitor my MPG constantly. Sometimes I drive without shoes! I also drive with all windows closed, and usually the A/C off. I also drive ONLY in the far right "slow" lane on the freeway. My speed tends to average around 52 MPH as this seems to be my "sweet spot" for my 4runner. I try to keep under 2000 RPMs when accelerating from a stoplight, and I hover around 1600 RPMs when on the freeway or city streets. I DRIVE WAY UNDER THE SPEED LIMIT and laugh as the idiots around me play the "ego" game of being first in line at stoplights.
Planned Mods:
None! I rely on driving techniques only. 70% of my daily driving is highway miles.
