#97 of 106 Re: Low Mileage [rpfingsten]
Jan 11, 2007 (6:21 am)
the mileage shown on the blue screen on my avy is usually about 1 mile mpg off
there is a reason for this - if your Av is like mine the trip odos read about 3-4% low, check it out with some hwy mileage markers - 100 miles shown actually is about 104 miles driven. If you add that 4% in that equation 25 mpg actually equals 26, I have found that the computer indicated mpg is actually right after the correction. Speedo, however, checks out as on the nuts - haven't figured out yet how the odo and speedo aren't both off the same amount, something that has been the case in any other car I've owned. The other problem I've run into in terms of verifying FE on a tank-by-tank basis is that the pumps will shutoff long before (a gallon or 2) the tank is really full - typically when my DTE is '0' the car will take about 16.5 to 17 gallons, but the gas pump (it depends on the station) can shutoff as early as 15.

Hi everyone: Don't have an Avalon but very interested in one, Is it true the Avalon does not have an instant mpg read out and you have to wait to fill up the tank to get the reading? If so that's kind of strange, even even my old OLDS minivan has it.

Yes you're correct. I just traded a 2000 Avalon XLS for a 2007 Avalon Limited, and trip computer now has less options than before. I do find that the two options (ave. mpg and miles to empty) are the ones I used before and they work great. Wow this is one great car!!!!! Far exceeds my expectations our 2000 XLS ran up 100000 miles without a hitch.

it doen't have anything for instanteous mpg (category: worthless information) but does keep avg mpg by the tank, elapsed time, and distance to empty. It automatically resets itself every time you fill up which is what is unusual because you can't get a multiple tank average on the computer (on a long trip, for example), but it does show mpg changes as the tank empties. Would encourage you to check the Avalon, has more than enough power to keep up with almost anything on the road and my little blue screen always reads about 27 mpg - amazing.

Hi Rich: You are right: the 05-07 Avalons do not have that instant MPG readout. But as someone else said, and I agree, having owned an '00, and currently own an '01 and just bot a new-to-me '06, (obviously we do like Avalons very much.), instant MPG is really rather useless,(except for bragging, as you point to 45 MPG, for example, as you coast down a hill) compared to the newer Av's which compute from fill-up to fill-up, and provide us with an MPG for that tank just replaced, which I feel is a more usefull number. Incidentally, I am proving to myself what a friend told me about a year ago, that 'country' gas gives MUCH better MPG than 'city' gas, due to the pollution-control additives mandated by states and/or feds? Can anyone provide more precise info on this subject?.......For example, fuel purchased in Waco, TX, (apparently 'country' fuel, gave us 36.6 MPG, whereas 'city' gas here in Fort Worth gives only about 30 MPG highway readout. And, yes, one should check total miles on a tankful divided by total gallons. I find THAT number to be just under what the on-board computer figure stated: about a 5% disapointment....Hey ain't this Edmunds Forum cool?!

true, instead of using MTBE (?), the Feds have mandated the use of 10% ethanol (both octane additives) in many cities across the US. This hurts gas mileage by 5-10% and also increases the price of the gas a bit. BTW, next time you take one of those good long highway trips check your trip odos vs. some mileage markers, think that will answer where some of your computer 'error' is.
#103 of 106 Grade of Gas?
Apr 21, 2007 (5:56 pm)
What grade of gas is everyone using? Do you have to use premium or is using regular ok?

Hi Rich: We are on our third Avalon, and in none of the three, has there ever been a drop of anything but regular. When we bot our first, a 2000, I did read in the manual, and on the filler cap, that you MUST use premium. I had been told by the salesman that regular was okay, so I called him to confirm, and he stood by his recommendation. I have been told that to approach federal milage standards, and the milage shown on the sticker, one would have to use Premium. I have gotten good milage in all three Avalons, and have never paid the premium price. Them's my thots....ovlee

On regular fuel (varying from 85 to 87 grade) on 1500-mile trip, got 30.58 mpg(US) at 75-80 mph on interstate.

On my 97 XLS, I use only regular gas and it runs great. I get 33.4 MPG at 60-65 MPH
