2008 Avalon Limited. I drive 42 miles to/from work every day. Using the in dash "computer" fuel economy gauge, averaging between 70 and 75 mph on interstate, I can definitely get 32 to 32.5 mpg. Have not crossreferenced the mpg reading vs actual gallons consumed but suspect it's in the ballpark. So, not BS.

I've gotten 33 mpg in my '06 Limited on several trips. I have yet to get that mileage in my '08 Limited however.

The current generation Avalon can hit 30+ mpg if driven in the right speed range on the highway. This is nothing new as my '99 XL could do it and actually did it a lot more often than my '07 Limited has to date.
 
Using a blended fuel with ethanol, say 10%, will reduce mileage by about 2%, maybe a little more, if you follow the textbook analysis of fuel composition. Any additional drop is due to different driving, math error or other factors. The load the vehicle carries makes little difference on a long trip unless you are the mountains. Speed is a critical factor as air resistance is exponential.
 
Always remember that Avalon odometers tend to be off by about 3% short so adjust all mileage calculations upward to compensate. Check the odo with the interstate mile markers when you get a chance, see if your car is off...mine is... Enjoy the Avy, all.. great value...

"BS
10% ethanol I have seen no decrease in fuel economy. Also if your driving at 70/75 mph there is no way your getting 33mph!
Again BS "

Since the new LS with a V8 seems to easily get 28 MPG at hwy speeds I see no reason the Avalon's V6, especially with DFI couldn't acheive 33 MPG. If the current Avalon doesn't have the GS's DFI V6 engine, 12:1 compression ratio, then expect reports of 35-36 once it does.

The quickest easiest and cheapest way to increase/decrease mileage or acceleration is to change the gear ratios
When Toyota went to the 6 speed trans it allowed them to make a better choice of gear ratio and still keep the trans shifting smoothly using a lower ratio for 1st gear for better acceleration and a very tall gear in 6th for better mileage
 
1800 rpm at 69 mph is only 1000rpm over idling no wonder it gives great mileage
 
Try this just for fun !
Set the cruse control at 69 as you are getting ready to go up an incline. the trans will shift back into 5th or 4th gear depending on how steep it is............NOW.... turn on the AC.....
And you wonder where your gas goes? LOLOL

2008 Ltd Mileage & Ethanol by dfurnier

We picked up ours in May. Recently took a 3000 mi trip and averaged almost 32mpg (based on my calculations) with a fairly heavy load at about 65-70mph. The car consistently claimed 33-35.
 
I prefer to use 100% gasoline as a personal protest, but it is very hard to find, at least as regular. (I believe ethanol is a terrible waste of tax dollars, raises food prices, etc.)

"..change the gear ratios..."
 
Well, yes, and...no....
 
If you have a CVT, Continuously Variable Transmission then regardless of road speed the engine can ALWAYS be made to operate at the lowest possible RPM, lowest frictional component, most optimal FE, wherein it just barely produces enough torque to move the car along at the desired speed and road conditions.
 
So it is the engine's low RPM torque production capability that is the real determining factor for constant speed cruising on the hwy.

I agree with you there. I read somewhere that it costs more to make the ethanol than the benefit if any we get from it.

On a recent business trip to FL I tracked my mileage doing both a calculation as well as taking the number provided by the car. I drove the first 230 miles on a highway with a 65 mph limit and a full tank. The car said 32.1. I stopped for lunch and filled back up. The calculation was 32.3. I drove the next 280 miles on I-95 between 70 and 80 mph. The car indicated 33.8 and the calculation was 33.2. Both fill ups were with 10% ethanol as clearly labeled on the pump. Not only did the car get 32 mpg+ on 10% ethanol but contrary to popular logic it got better mileage above 70 mph. Go figure.
