Regarding hypermiling, I've been doing some things and getting 22.5 mpg:
- coasting in neutral, with auto trans, with engine off- but i heard this is bad
so i stopped doing it.
- anticipating lights- coasting along the road if i know i'm going to stop anyway and trying to beat red lights
- shut off engine at red lights
- slow acceleration
- drive at or below speed limit
- 30 seconds only to warm up engine
* thinking about converting it to a plug in hybrid when it's paid for.
* How's it going achi10?

Seriously, I don't hypermile, but I do try to drive a bit more conservatively on long highway trips. I've noticed a difference there, but I haven't seen any appreciable difference on backroads, no matter how I drive.

Citgo = Venenzuela = Hugo Chavez.... i simply don't buy citgo
That said, I get 19.5 MPG and it doesn't matter where I get the gas. I drive between 40 and 45 mph and take routes that minimize the red lights. I try to drive behind another vehicle when possible so as to get some type of draft (but I do not tailgate).
I seriously think that there are certain speeds that take advantage of inertia. 40 - 45 mph and 60 - 65 mph seem to be good inertia speeds that minimize the need for a lead foot.

Snipped...I've read all the threads on here and the one about buying gas at different stations seems odd. I think that guy either owns a Citgo station or he has Citgo stock. 
I mean the whole reason behind this is the save money so I typically go to the cheapest I can find in my area...Snipped
Summary:
Proper Tire Inflation
Coast whenever safely possible
No downshifting
Shift at low RPM's
Good luck!

My wife often buys gas from Kroger for the JK (not sure what brand theirs is). With the 87 octane, mileage dropped down to 14MPG. Using the mid range it came back up to 17-18. Other brands have yielded the same 17-18MPG in 87 octane.
Our '78 Monte Carlo won't run on the Racetrack or Kroger 87 without pinging under load. It runs fine on BP/Amoco and Citgo 87 fuels.
As always results may vary, but it works for us.
As far as your advice on hypermilling and tire inflation, I agree. I think a lot of the less radical techniques are just common sense driving that all us crazy in-a-hurry drivers just forgot or were never taught. I have a 20+ mile commute of divided highway, some with traffic lights and some freeway type driving. I see other drivers constantly accelerating rapidly, not paying attention to the traffic pattern, changing lanes unnecessarily, etc. which causes them to speed up and slow down more than they would have to otherwise.

I had always been under the impression that "coasting" in N damages the auto box and causes un-necessary wear to the transmission
I got this from my ex bro in law, a mechanic for Ford, Vauxhall and now works for Cosworth I believe - So I may be wrong
I do have a diesel, and I didnt realise the speedo's were diff tbh, i was ready to join the 100 club but my camera wasnt to hand lol!
btw, what octaneis the Petrol in the US?? we mostly have 98octane here now rather than 95, and i tend to use the Diesel Optimax/Ultimate, again higher refined and is supposed to provide better power, less burn and more mpg

I dont get it when I was stock I got a 23 mpg all the time driving around town and what not
I understand the princible behind it but as long as you are not driving let a idiot and not in a rush anywhere you will get good mpg
I have a 01 ranger 4x4 I drove for about 4 years befreo I got the jk the wife now drives it and complained about the mpg she would get about 14 - 13 mpg in it while I was getting close to 20 she would drive like a idiot as I call got to get up to speed the quickest and what not
I should her how to drive the truck as a normal person on the highway ( had a 200 mile trip ) and got 26 mpg
