Car mfgr: Chevy
Car model/body style: Malibu LS
Year: 2005
Engine size (displacement/cyl): 3.5L / 6cyl
Transmission type (auto/manual): Auto

MPG info (estimates from memory, check every tank, but never recorded)

MPG before hypermiling: 30
MPG currently achieved: 33-34

Specifics

Location of primary driving (country/state): Arizona
Miles driven per year: 36,000 last year, 20-30% city, the res freeway

List all tools/techniques used to achieve current MPG:
  • Accelerate like a scooter pulling a cattle trailer
  • SLOW DOWN! Used to drive 80-85 mph on freeway, now I keep it 65-70, unless running late.
  • Don't drive into the Mexico plant, park at the border and catch a ride. Saves from idling in the slow moving line for anywhere from 15 minutes to well over an hour.
  • Coast to red lights. Always done it, just try and do it better now
  • "Draft", not close, but if I come up on a tractor trailer doing a few mph slower than myself I'll just follow along instead of passing. This probably makes the biggest difference so far.


I ordered a ScanGauge II on Sunday, we'll see what I learn from playing with that. I'm pretty happy to be able to pull 30+ mpg from a decent sized car with a V6 and slushbox tranny. The whole hypermiling thing is fun in a sense of seeing how good you can do, but it's kind of tough for me. Work pays the gas for my traveling, so driving slow and saving gas costs me time and doesn't save me money, although I get some satisfaction from being less wasteful.

Note: NOT all technique...

Car mfgr: Acura
Car model/body style: Integra LS, 3-Door
Year: 1998
Engine size (displacement/cyl): 1.8L / I-4
Transmission type (auto/manual): 4-Speed Automatic with locking torque converter and "Hill Logic Control"

MPG info:

MPG before hypermiling: 24-25
MPG currently achieved: 34

Specifics:

Location of primary driving (country/state): Kansas City Area
Miles driven per year: ~15,000

Mods/Tools:
*Max timing advance
*Winter Grille Block
*Transmission-Throttle Cable Tightened to Max Limit
*Cruise Control Throttle-Limiting System (CCTLS) (limits maximum throttle in cruise)
*Temperature-Adjustable Air Intake -- Target = 100F (WAI)
*PCV Bypass Oil Catch Bottle
*ScanGuage-II Monitoring and Feedback
*Synthetic Transmission Fluid Change
*Davis CarChip E/X OBD-II DataLogger
*Seafoam Cleanse x3 (Manifold); x1 Crankcase
*192-Degree Thermostat (170 = Stock)
*LRR Michelin MXV4-Plus XSE Tires
*Tire Over-Inflation
*OEM Engine Block Heater (with timer)
*Antenna Mod
*Exhaust manifold heat shield delete (for under-hood heat: intake, etc.)
*Splash Guard Delete x4 with underbody pans behind the rear wheels

Technique:

*Moderate Acceleration to 35 (TC lockup), with throttle-lift shifts
*Gradual Acceleration after TC lockup
*Light Timing / DWB
*DWL / Pulse-Glide (hills only)
*Corridor Effect
*Manual A/C operation when needed, or vent-only / windows cracked on highway -- down in town
*Coast, Coast, Coast...
*Minimal EOC (messes with the transmission computer and the TC lockup calcs)
*Lower Highway Cruising Speed
*Engine-off idle (if >1 Minute)
*Downshift on decel (if necessary) to keep engine speeds in DFCO range

I think that covers most of it

Specifics

List all tools/techniques used to achieve current MPG: driving SLOWER, light on the pedal to maintain low RPMs, non-aggressive acceleration, timing green lights, coasting to stops (engine ON) instead of accelerating towards them, pulse & glide on the freeway (engine ON), pushing my car out of the driveway instead of starting the car first, not using the A/C, maintaining constant throttle (instead of constant speed), when on freeway--"driving without brakes"

all mods to my technique...none to my car

MPG currently achieved: 38 no SGII; 41 with SGII
Specifics

Location of primary driving (country/state): California, USA
Miles driven per year: 12,000
List all tools/techniques used to achieve current MPG:
- slow down more
- get to max gear sooner and find "sweet spot" quicker; fuel-cut when possible
- neutral-on coasting
- no A/C
- avoid highways if possbile
- reverse into driveway
- park in pull-outs or pull-throughs
- use Scangauge
- blocked decorative divots
- partial grill blocks
- removed antenna
- pumped tires up to 40psi

EDIT: updated with SGII tank MPG after calibration. I'm usine NICE-ON more now and it compensates for some of those pesky stoplights.
