Somebody asked, and it looks like a valid question:

What do all the acronyms mean?

Wayne Gerdes started this, he's big into efficiency, apparently with his syllables too. TLAs (Three-Letter Acronyms) appear to be a serious fashion with ecoheads. But I digress.

In no specific order
AD = Aerodynamic Drag
AS = Auto Stop. A hybrid feature that shuts the engine off automatically
FAS = Forced Auto Stop. Like above, but forced by the driver. Also applies to non-hybrids, but the TLA is the same.

FE = Fuel Efficiency
ME = Maximum Efficiency
SG = ScanGauge. A device that reads info from the engine control module and can provide real-time fuel usage data. Super-handy for driving habit alteration.

DWB = Driving Without Brakes. No, not really! But drive as if you don't have brakes. Ease up on acceleration, start permitting coast-downs from way, way out. Using brakes means throwing away energy you've invested in getting the car up to speed.

EOC = Engine Off Operation. Continued driving after FAS. You're still moving, but the engine is now merely a passenger.

BS = Bump Start. Starting the engine by popping the clutch in gear.
ICE = Internal Combustion Engine.
DFAS = Draft-assisted Forced Auto Stop. Extending EOC by coasting along in the wake of a leading vehicle. Highly Dangerous, not recommended

P&G = Pulse and Glide. Engine on, pulse to an upper boundary speed, engine off (or shift to neutral) and glide to a lower boundary speed. This is a proven effective technique for maximum FE, but maddening to other traffic.

FCD = Fuel Consumption Display. Like a ScanGauge, but factory-installed.
MPG = Miles Per Gallon. You already knew that.
YMMV = Your Mileage May Vary. The cliched and oh-so-true warning from the EPA that their mileage ratings were, in fact, bogus. Not so much the case anymore, and around here, they're wrong the other way: they're too low.

That's all I've got for now. If anyone wants to tack any on, go nuts.

I actually did set up a wiki that died in the Digg/Ecomodder Great Crash of 2008 (TM) (or whatever andrew has named it)...I'll set it back up this weekend and we'll see about creating some entries for boring stuff like that. Just need to make sure not to detract content from the site or anything like that.

Lightbulb Wiktionary

http://en.wiktionary.org/wiki/Appendix:Internet_slang#I

Wikipedia has an appendix for slang.
Some of our stuff is there already.
We just need to update it with acronyms we use that others might not get.
Then you just put it in the tab next to your EM tab. & VoilĂ* instant reference.

People here use EOC instead of EOO to mean the same thing? I thought it meant Engine off Coasting, but I could be wrong.

EOC is engine off coasting.

EOO could be sitting in the car with the radio on for all I know,

I meant to put it in as EOC - I've edited it now.
