Interesting that you haven't noticed a difference thus far. Everyone else reported at least a 3MPG gain. Do you soley use your scangauge, or do you calcuate your MPG yourself?

Here's my secret to filling up my car about twice a month..

My work is less than a mile away.
My school is less than 2 miles away.

Leisurely driving is done in my CRX.

But I'm better off flaunting the Yaris...

Someone once said that somewhere on the forums.. Can't remember who.

I recently bought a PLX Kiwi and was looking at the sensor diagnostic info that was being displayed. I played with it a little bit to see if the it did anything. Using the A/C puts more strain on the engine (doing approx. 10-15% more work), so while it may not directly affect the MPG, it is causing your engine to work less effectively and thus causing worse gas mileage.

yeah, I was along your lines of thinking- I am around HB (in Lakewood), so AC isnt really that necessary. I didn't think it made much of a difference, but when I just sat in the garage idling, and saw how much more work the engine needed to do with the a/c on, i was like "DAYMMMMM!!!!" :)

-Turn car off as soon as I come to my destination, then do everything else (put in park, put windows up, etc.)
-Let car idle only for 30 seconds to warm up, otherwise none

I can't think of anything else. Let's get this FE section bumpin'!
I do the same as you have posted. Even when I pull up to an ATM I turn the car off. When I get in the car, I put on seatbelt first before starting the car.
As far as ac usage, only use when really hot, mostly drive with window open a little and not into heating season yet, but that is coming quickly with frosted windows.

If the AC does, I'm guessing the heater does as well

One important tip for the road is to avoid tailgating. On a recent road trip I stayed at least 6 cars lengths away from the car in front of me and found myself braking and re-accelerating a lot less when I was 2-3 car lengths away. Anticipating lane changes on the highway was something that took a bit of time to get used to. All this coupled with driving the speed limit got me my highest MPG yet (44).

Using the heat without running the a/c compressor does not have a noticeable impact.

I think that I have not seen any changes after switching to 0w-30 because of my unpredictable commute. Some days I can get home in 15 minutes, other days it takes over an hour.

Personally, I find coasting makes me feel noot in control. In fact, in some jurisdictions, coasting is illegal.

You missed one mileage maker, and it's a good one: inflate the tires past the recommendations. Even 5lbs makes a big difference...

My "Tricks"

1) Look for every opportunity to take your foot off the accelerator (DFCO)

2) Tires @ max pressure (44psi)

3) Drive Speed Limit or slightly under

4) Shut off engine at construction zone lights (long lights)

5) Put AT in N at short lights (idle w/o load)

6) Back off accelerator while attempting to maintain constant speed (attempting "Hang Time" w/o scangauge)

7) Cycle AC off and on - on for the shortest period of time necessary to be comfortable

8) Avoid drive throughs like the plague

Currently averaging just under 42 mpg - high tank 43, low (first tank 38).

One thing I observed - driving for best mileage is very difficult on roads you aren't familiar with. We took a trip this past weekend through missouri hills and I was in a constant state of mpg panic! I was trying to DWL, but I think I failed. Yielded 41. I had hoped for much higher considering the amount of highway miles on this trip! :(

I asked this before the hack - when do you cross over from "cautious driver" into "hyper-miler"?
