85 octane is used in higher altitudes. It would not be good at sea level..

Well, thanks for all the ideas, everyone. I do keep a close eye on tire pressure (33psi) and the air filter, rj2112, and I religiously change the 5W-30 oil myself. But, I don't think I'm willing to change all of my driving habits (or give up AC!) to eke out a few more mpg.
We got this car from Carmax about 5 years ago, and although they reportedly examine everything thoroughly, I can't help but wonder what might have happened to the car before I bought it. (As an aside, within a week after purchasing, we had to bring the car back to Carmax; it was shaking badly because a couple engine mounts had failed—something that Carmax is supposed to check during their inspection process.)

I'm in WA State, so no imperial gallons for me. I have a 2000 echo, 2 door 5 speed, totally stripped (it doesnt even have a clock). The only repair in the life of the car (in mid 130k now) aside from belts, fluids, and brakes (routine maintenance) has been a mass airflow sensor. I always use the cheapest gas I can find, which in WA means 87 octane from Safeway or Arco. On summer trips to the Rockies I buy 85, which is available out there. I've calculated the vast majority of tanks over the last 70k miles and average 46mpg total over that time, 48mpg highway (obviously the vast majority of my driving is highway). I drive pretty gently: steady speeds right around speed limit, slow down to time stoplights, avoid using brakes, etc.

Maybe the car was abused before you got it. But I did just notice that the 2003 automatic is only rated for 36mpg highway, according to the new system. At 78mph, with air conditioner, loaded up...33 doesn't sound bad. At 65mpg and no air conditioner I bet you'd exceed govt estimate, though as you say it may not be worth it to you.

I will slow down for better fuel economy, in fact that is the express reason I stick to the speed limit, but I won't limit A/C use for a couple mpg - I use it all the time when the weather is hot. And it's hot a solid 4-5 months a year, I'm in California.
The worst mileage I ever get is not in the summer with the A/C running constantly, but in the coldest part of winter, because the car takes longer to warm up (and I often idle it for a bit while I wipe the windows so I can see out, and so the defroster will work as soon as I get on the road).
The per-tank mileage is very consistent for me in this car: 40-41 mpg in summer, 42 in spring and fall (less A/C use, mild nights), 39 in winter. That is for my typical suburban driving, including my commute which only sometimes has traffic. A trip out of town on the highway will net me a 5-7 point gain.
#421 of 435 Yep, I am in that range now...

Oops, I hit enter.. and the title was posted, but I wanted to say my '01 does about the same for MPG. But every once in awhile I can get a 50 MPG on a 60 mph trip. And I will always use A/C when needed. Just like at home, I have it to use and I will use it when needed . I've had the '01 Echo since 2003 now, it's been technically totaled out two times now, and the last time we were on a Judge Judy show to make a settlement. 150K on her, but the old Toyo just keeps going, but it does feel the pain of the Northern Wisconsin roads up here compared to the Twin Cities where we drove before. It now is shadowed by the big logger rigs and 3/4 ton Ford pickups around the area. Soo... I am learning all about replacing sway grommets, etc. Wisconsin gas is right up there- and still at $4 per gallon close to June. Chow for now, Mark in Winter, Wi.

FWIW I bought my ECHO from Bremerton Toyota, in 2000. Another stripper, 5 sp 2 door, with an AM radio. Manual windows. After 5 years I added a CD player. I've done the brakes, and replaced the struts. 3rd set of tires.
It spent the first 50K miles driving between Port Orchard, and Redmond, WA. Nasty drive. The next 60K or so saw me going from Pt Orchard to Dupont, WA. Then from Pt Orchard to Hillsboro, OR. 5 years of driving between Hillsboro and Rainier, OR.
Now I drive 48 miles one way to work in rural VA. The car has about 210K on it and it's needed basic maintenance.
My GPS tells me that my average speed over the last 3,000 miles is 48 MPH.
I have observed that if you refill the tank at the half way point, the MPG is considerably lower than if you run the tank all the way down. Lower 30's. If I run to the blinking light and then fill, I get 41-43 MPG running 89 Octane.
In the same conditions, with 87 Octane, I get 35-38 MPG.

I've noticed this too about the mileage that I get at different re-fill points. If I fill up at 3/4 tank, I get about 44 per gallon. At the half way point, I'm getting about 35. When I go down to fumes, I'm back up to the 44 per gallon range. Nothing changes with my driving habits. Weirdness.
I have found that if I drive with my windows down consistently that my mileage is about the same as if I ran the AC consistently too. It was 91 today and will be that way for about the next four months. I have to have the AC going, so my stellar 44 mpg is going to be on hiatus for a bit. 95 degrees with the windows down at 60 mph feels like I'm standing behind a bus.

As far as the AC goes, supposedly with modern cars AC is more efficient than driving with the windows down, which causes incredible drag. That makes a fair amount of sense to me.
The issue of half filled tanks makes less sense to me (though I'm not disputing what you say). I always go from empty to full, so I have no personal experience on this. But my very best tanks (those of 50mpg or above) have all come on roadtrips when the car was very heavily loaded. And five gallons of gas I would think does not weigh enough to make a big difference.
