I went to San Francisco this weekend, and on the way there, I probably averaged about 75mph and it returned 31mpg - which is not bad, it is actually more than what the current EPA ratings state. (29mpg).
On my way back, I forced myself to cruise at 65mph all the way, a total of 430 miles down the 101, a very nice california scenic drive - and I did not want to fill up the entire way back, my goal was to start with a full tank and arrive with an empty one, and that's what happened, my mileage clocked 431 miles and the gas pump clocked 11.3galons, it took me 7 hours to arrive. that's 38mpg!!!
I preferred to turture myself at that speed, than to turture my walled with more fillups @ very close to $5.00 a gallon.

Excellent mileage: Gator,
Was there a tailwind on the way back. lol.
I am currently trying to reach 35 MPG, 100% city

Wow, that's great mileage, but I'm not sure I could tolerate the extra time. It usually takes me about 5 hours to make it to SF up the I5 (about 400 miles). By my calcs, you would have used 13 gallons at the higher speed and just over 10 gallons (on the 5) at your slower rate. Of course, you would have been run over long before you arrived if you did 65 on the 5, but I think your time is probably worth more than $7.50/hr. :)

Definately the extra $$ was not REALLY that much worth the extra time it took me. It was really painful, I felt like a turtle. (according to my calculations $10.00) not a big deal though LOL. It actually was more of a test, I figured since I have to drive it, might as well. So i did, and I liked the results ! Next time, i'll try 70mph on my way there. and 75mph on my way back (or vice versa, I don't know) and i'll post the results. I wonder if 70mph would return similar mileage?

DAMN!, that's just impossible as everytime you're at a red light, you're at 0mpg and accelerations at low speed, etc, - it's hard for that to happen. I don't think its even possible to hit 30's. Is it?

It might be possible. I decided to play a little with my TL today. The only issue is that I had to rely entirely on my trip computer since fill up was out of question for this 27 mile round trip. But, I have seen 24-28 mpg and a 30 mpg run on this stretch that involves about 50 lights, moderate traffic, relatively flat stretch with about 3 miles on freeway.
In addition to doing everything I had done to get 29-30 mpg on a previous run, I decided to turn off the engine at most lights, and got an amazing result showing in the trip computer... 34 mpg. My average speed was only 31 mph (calculated, since turning off the engine at lights leaves the "idle" time unaccounted for).
So, if TL can do it, I'm sure Si can as well. I'm planning to use these tricks on an entire tank in my 1998 Accord (EPA rated 21/27), and so far the movement of fuel indicator bodes well with 30+ mpg estimate. It is driven mostly on the same stretch.

oh yea, turning off your engine will definately help, a lot. I hope this is only for a trial right? - I don't think its that good for your engine and/or starter to get turned on/off so many times in a row though. Just sayin - but I think if you're able to achieve the 30mpg this way, you'll be able to hit about 27-28mpg withough turning the engine off.

It was for trial on my TL, but I will use it more on Accord. Since I drive about 13-14 mile on each trip thru these lights, I get to shut off the engine only occasionally (picking the longest lights), which would be no worse than taking short trips but with warm engine.
I did get 28.8 mpg on my Accord on a tank without shutting off the engine. Pretty impressive considering its age and the route (only ~15% freeway).

What is the cutoof time between starting tha car as opposed to letting it idle? Starting the car uses X amount of gas compared to idling X amount of time.

I'm using a 15-seconds plus rule.

Well my last tank 95% city was over 31, that before my new sparkplugs, synthetic oil, and air filter change, just using my cycle skills, basically pedal - coast, coast down hill, drive sensibly about 5MPH over the posted speed limit.
I refuse to turn off the car at red lights, too dangerous and too much strain on the startup components, altough I was tempted on my last tank after waiting 15 minutes idle in a construction zone.
I will probably not make 30MPG with this tank as I already hit 8000RPM once already (couldnt' resist).

Driving south on HWY 99 from Fresno to Bakersfield I decided to get some consistent numbers for a completely flat highway cruise. Speed limit is 70 MPH once you leave Fresno and until you get a few miles north of Bakersfield. Where the highway "dives" below overpasses I used manual throttle inputs to accelerate slightly on the descent and decelerate slightly back to 70 MPH by the top of the ascent, essentially keeping LOD (for those ScanGauge users out there) constant and minimize the effects of these slight terrain changes. Same technique was used for overpasses, which there aren't nearly as many of on this stretch of highway. Tire pressure was 40 PSI @ 90F "cold" since that's what my garage runs right now (roughly equivalent to 38 PSI at 70F). Outside temps were in the high 90's and the A/C was on the entire time.
I reset my trip gauge once I hit the freeway and at the start of each run after stabilizing at a test speed and over the course of 10 miles @ 65 MPH I saw 38.2 MPG. Once the speed limit stepped up to 70 I did too and reset the trip gauge and over 60 miles I saw 36.8 MPG. I then bumped it up to 75 MPH for a little over 10 miles and turned in 33.6 MPG. For S&G's I dropped it back to 65 for 10 miles once the highway had opened back up to 3 lanes and saw 42.5 MPG!?!? No hypermiling besides the constant LOD driving I mentioned earlier, no drafting, etc. I didn't see much in the way of wind (air quality was HORRIBLE last weekend in the Central Valley with wildfire smoke and smog, so winds were light). I'm not quite ready to believe 42.5 MPG on a flat at 65 MPH even though it is in family with the MPG improvement I saw between 70 and 75 MPH. The last 10 miles in to B-Field I bumped it back up to 70 and saw just under 37, same as earlier that drive.
I'm going to need to do some more sampling to validate what 65 MPH yields before I'm willing to stand by that 42.5 MPG number but I do have some ideas why it was higher than when I first got on the freeway.
-When I hit the freeway I'd only been driving the car for a few minutes so while the engine coolant was warmed up perhaps the engine oil wasn't quite there and I'm sure the transmission wouldn't have had time to get all of the way up to temp. The tires wouldn't be quite as hot yet either so their rolling resistance would be a little bit high as well.
-The interior of the car had been heat soaked prior to hitting the road so the A/C compressor would have been loaded heavier than it would be once everything is cooled 10-15 minutes down the road.
I continue to be amazed at how well the Si can do if you want to coax great mileage out of it.
