Avalon gas mileage?

[BiXLL]

I am considering purchasing a 2002 Avalon with 107,000 miles on it. It has the 3.0 V6 in it and I am wondering what kind of fuel mileage I could expect from this car. Can anybody help with this, and any known problems with the car?

I have a 2003 Avalon XL with 68,000 miles on it. To date I have averaged 22.4 mpg overall but that is with ~ 65% city driving. Interstate highway runs across PA and OH can get 28-30 mpg.

Hope this helps.

On the highways in flat central Illinois I have no problem getting 31 mpg on my 2000 avy with 148,000 miles on it. Around town I get 23 to 25 mpg.

These are the kind of numbers I was hoping for, thanks for your feedback guys!

I am getting 26.5 before the tune up. Have not checked since I just put the new plugs in. Hopefully better now. I live out of town about 6 miles so my driving is a mix of town and country/highway.

I just ran back and forth to work all week as well as some errand running the weekend before. Had 310 miles and took 11.4 gallons which works out to 27.1 mpg. I did drive very mileage conscious, but I know I can get at least that good if I want to, and I am very happy with that considering the ride and comfort the car provides.

My mileage varies a lot between city and highway mileage. In the city I get about 19 MPG, but on the highway if I go 65 MPH I can get 32 MPG (70 MPH produces about 30.5) Average mileage per tankful for typical 60 city/40 highway driving is about 23 MPG. Interesting thing is my Highlander gets about the same mileage in the city.

I can get 22-24 MPG city/locally

I get 31+ Highway Going 55-70 MPH

I gotten 35.7 AVG (shown in the multi-function display) from Florence, KY to Evendale, Ohio. Going about 60-70 MPH oooh yeeaah! lol

I get 24-25 mpg on mixed city/freeway driving.

I can get 26-28 if I do mostly freeway driving.

2002 XL

On highway trips with cruise set at 72 and the usual 10 miles of local driving at either end, I get 27.x mpg.

Suburban mix of commute and local shopping, etc. runs 21.x.

With my '04 XLS I can get 31+ mpg doing 70-75. I have also used synthetic oil since new. It now has 117,000 miles and I just changed the original spark plugs tonight.

how was it for you?

Just did the original plugs on our '04 Avalon with 117,000 miles. I've been putting it off for months after reading some of the difficulties others have had. Took a little over an hour do do all 6. I've seen more difficult jobs.

The plenum does not have to come off. And I didn't use an air ratchet. Besides my 2 big hands here's what I used:

5/8" flexible spark plug socket (3/8" drive)
6" extension
3" extension
1 1/2" extension
A flex head 3/8" ratchet (mine is a long Blackhawk # 34947)
3/8" fine tooth ratchet
10 mm offset ratchet wrench or 10 mm shallow socket (wrench is smaller)
Needle nose pliers and a small flat blade screwdriver to gently squeeze/pry the clip to remove the wire connector
Anti-seize lubricant for the plugs and coil hold down bolts

After letting the engine cool a bit I did the driver's rear plug first. Screwdriver used to unclip the wire connector from the coil. Use the spark plug socket with the 1 1/2 and 3" extensions and flex head ratchet in the space between the plenum runners. Duct tape the 3 pieces together where they meet. That will absolutely save you a lot of grief. No electrical tape - it will melt and fall off. After taking out the coil by removing the one 10mm bolt holding it, slide the socket assembly down and catch the plug before putting on the ratchet wrench. Once loosened, remove the ratchet wrench and unscrew the socket assembly with the plug. Install the new plug the same way with a little anti-seize on the threads (makes screwing the plug in easier). Do not plug the wire connector on yet -leaving it off gives you a little more working room for the center plug.

I did the right rear next again with the flex head ratchet. Unplug the vacuum hose on the plenum near the plug and push aside. As you remove the coil turn it 180 degrees to work it out around the obstacles. Install the new plug but not the coil yet. By reaching around and through the runners of the plenum the center plug will come out with the fine tooth ratchet. Once the center plug is in reinstall the right rear coil and plug in all 3 coils.

Front plugs only need the 6" or longer extension taped to the spark plug socket.

I used the OE Denso Iridium plugs and the engine felt more responsive even though the gap on the old plugs was 042".

do I need to change coils along with the spark plugs? anything else?
