Go figure: The variation in mpg is due to something other than the fuel. Alcohol has less heat energy than gasoline per pound so mileage must be reduced when pump gas is diluted with ethanol. This is basic carbon chemistry and has nothing to do with the car or the trip. Also, a vehicle travelling at a higher speed uses significantly more energy (based on the standard ABC power formula) to maintain that speed. The difference between 60 and 65 mph is about 25% so going to 75 is... wow..... The point here is that actual mpg can be difficult to determine due to a variety of factors such as putting gas in a tank and thinking it's full, odometer error, etc.
 
But at 32+ mpg... that's great! Who cares about exact speed or fuel composition...

Mack,
 
  Any more thoughts on the replacement of the Avalon? Maybe in 2010? It seems that the 2009 will be like the 2008 except the VSC will be standard from looking at some of the SE dealers inventory.
 
Thanks,
 
George

Just to jump in here with my 2 cents;, a couple of months ago we drove to Utah in an '08 Avalon Ltd. I did a test. From Hot Springs, AR to Shawnee, OK (just east of OK City) I did the speed limit (75 on I40 in OK) and coming back from El Reno, OK (just west of OK City) to Hot Springs, AR, I did 5 miles under the speed limit. Neither way was there any traffic to speak of. I got better mileage at the speed limit: 31.3 vs 30.8 at 5 miles below. Of course this is very unscientific and there are a lot of variables and I don't know if I was using anything with ethanol; all though, in Hot Springs it was Valero and in El Reno it was Murphy (Wal-Mart). As far as the overall trip is concerned we drove for 10 days, 4 days of which was city driving and 2 days of mountain driving in CO. That gave us an overall of 29.8 mpg. Also, when I fill up I squeeze in as much as I can.

After reading the posted mileage, I feel pretty good. On a recent 290 mi trip at 60mph with no a/c, I got 37 mpg.

Haven't heard anymore on it. As soon as I find something out I'll let you guys know.
  
 
PS, we are keeping the Solara convertible. The hardtop is gone after 08.

If its a new car, seems it might be covered under warranty. Obviously, there is a defect.

" Also, when I fill up I squeeze in as much as I can."
I believe squeezing in more is not a good idea. It heats up, expands, and leaks out. That's something I learned many years ago. Don't know if it's still true.
 
"it got better mileage above 70 mph"
Not sure, but it seemed to me, that we got better mileage at 70ish than we did at lower speeds.
 
"I read somewhere that it costs more to make the ethanol than the benefit if any we get from it"
According to Popular Science, at best it's 1 unit of energy in to generate 1.1 units out.

Re: '08 Avalon engine air filter removal [loesshill] by pappydsp

I have a 2007 Avalon and replaced the airfilter and cabin filter yesterday. The air filter can be a little tricky. I wouldn't attempt it without complete removal of the top of the air box as the paper filament may tear if you attempt to squeeze it in between the top and bottom halves.
The following procedure worked for me:
Remove the 3 vacuum tubes on the front of the box, disconnect the sensor wire from the top of the box by simply pulling it off and away. Loosen the phillips screw on the hose clamp that connects the top of the filter box to the air intake and push the 4 inch intake hose away from the top of the filter box. Unclip the 3 retaining clips by pulling the ring up from the bottom. There are two hinge type connections at the rear of the air box. Lift up the airbox top from the front and carefully unhinge the back from the bottom of the box by applying slight downward pressure as you are lifting the front portion. The top of the air filter box should then come off. The filter itself may be inside the top of bottom of the box. Simply remove it and discard it.
I replaced my old filter with a puroator #A45650. With the top of the air fliter box off, you can clean out the debris in the bottom of the air filter box, and wipe away loose dirt from the top and bottom halves. Place the new filter into the top of the air filter box and seat it SNUGGLY inside. Now reseat the air box top on the rear bottom hinge joints and lower the top down fully. Now fasten the 3 spring clips. If the clips do not fasten, do not force them. Re-check to make sure that the filter is seated properly and that the hinges are secure in the rear. You should not be able to see any of the filter showing between the bottom and top sections when the top and bottom halves are together. The filter is triangular shaped on the 2007 and can only be seated in the filter box one way. Continue reassembling in the order that you disassembled it. If you are worried about the vacuum tubes being replaced correctly, use tape and mark them before you take it apart.
