I conducted an "experiment" on July 7th. I was in southern California for a family reunion that weekend (as I was the last several years). This year, after filling up in Barstow, I drove @ 65 MPH from Barstow to Flagstaff, instead of driving the 70-75MPH speed limit. I saved enough gasoline to commute to work for 3 days before needing to fill-up. 32.9 MPG vs 27.9 MPG. And it only cost me 35 minutes of time doing something I really enjoy. (I really enjoy driving my Mustang.)
No one honked at me, no one shot at me, no one even gave me the finger!
Driving slower on the interstate highways can make a BIG difference in FE.
