Poll: MPG before and after hypermiling

[millenniumtree]

Mine is ALL technique. I really haven't modified the car at all (well, anything that would change MPG anyway)

1989 Honda Civic Hatch Std 1.5L 16-valve fuel Injection
Manual 4-speed

Previous (~34mpg average)
Current (~53mpg average of 2 tanks)

I pretty much only drive to work and back, 14.4 miles one way, 5 days a week.
Miles/Year: about 7000

Hypermiling techniques:
DWL, DWB
Lots of EOC & some neutral coasting Generally 60-50, but I'll drop to 40 before a pulse if there's no one behind me.
Max speed 60mph
No A/C (doesn't have one)
No idling
Pull-through parking whenever possible
No real instrumentation (not even a tachometer!)
I can usually coast about 6 miles of my 14 mile trip every day.

Location of primary driving (country/state): Western New York
Miles driven per year: 20,000
List all tools/techniques used to achieve current MPG:
Easy accelerations, coast to stops, leaving buffers between me and car ahead to avoid braking, staying close to speed limit, engine off at idle, trying to maintain a steady throttle position, full tune up on car, tires hyperflated to 38 psi (now trying 40psi), covered fake vents on front bumper, partial grill block, added cruise control for long trips.

I use ScanGauge II heavily.

Specifics

Location of primary driving (country/state): SW MI
Miles driven per year: 5000
List all tools/techniques used to achieve current MPG:
EOC = Engine off coasting
EOC while motor is cold!
EOC 35 mph - 55mph with 5th gear
EOC 25 mph - 55mph with 4rth and 5th gear
EOC 25 mph - 40 mph with 4rth gear
Chug along at 35 mph in 5th or 25 mph in 4rth gear in low speed zones
When you are on a four lane road, EOC for sure
When you are on busy 2 lane roads, chug along at 3 under the speed limit
Light timing
Slow coasting to stops with motor off
Choose country roads with few stop signs and little traffic
Tire pressure 40 psi
Never exceed 55mph
Cruising speed in 55 mph zone is 52mph
Shift at low rpms, just a blip of the throttle in the lower gears
Use torque of motor at low rpms, never wind it out
Learn the roads, avoid speeding up just before a hill with a stop sign beyond it
Motor off at lights
Fast turns to preserve momentum
Force people to pass by slowing down when there is passing opportunity
I wear an odd hat so people think I am nuts or old
I enjoy how I am saving gas in my own vehicle plus the 20 behind me

MPG before hypermiling: 40
MPG currently achieved: 50

Specifics

Location of primary driving (country/state): VT/NH
Miles driven per year: 7500
List all tools/techniques used to achieve current MPG: drive on slower roads, shift 1-3-5 while accelerating, shift into 5th at 25mph when not climbing hills, neutral coasting down hills, SGII, leave the AC off most of the time, keeping tires inflated. One negative is that I'm currently wearing out a set of snow tires.

With all the hills around here, where I'm driving makes a big difference. I basically use my car to drive to work, to a farm to pick up milk once a week, and to the dump on weekends. Out to the farm and back I average about 58mpg, commuting was 48 there and 51 back (my company moved to a new location last week and I haven't yet done a "normal" commute to the new location), and somewhat lower going out to the dump (around 45, I think).

I've used the SGII to determine that I can shift into 5th at 25mph, and that I do the best between 35 and 45mph, so I try to stay in that range when I can.

Hi,

Before, 37mpg+ average (over three years, winter and summer)

Now, my 90 day average is 44mpg+.

Before, my high was 41.8mpg and now it is 47.7mpg.

About a 6-7mpg spread for each.

Oh, before I started ecodriving, the most miles on a tank was 427.1.

Now 509.3 miles -- an increase of 84.9 miles!
