    The octain may get you a slightly better mileage but the computer retards the timing automatically and generally prevents knocking. The Car Talk guys have mentioned this in their column and on their riadio show many times. I've got a 96 avy in my garage with 110,000 miles and it has seldom seen hi-test and I have never had the first engine problem (knock on wood). However, horsepower is affected due to the timing adjustment made by the computer. On trips between Indianapolis and Columbus (200 miles of the flatest land in the country) I average right around 30 mpg if I keep it under 75. I get close to 27 around town on the freeways. I've got about 3,500 miles on my 2005 Ltd. What a great car.

    I have gotten over 30 mpg a couple of times on my 1997 Dodge Intrepid, 3.5 I would expect to see similar on a highway cruise from Avalon

    Just wondering. Was the calculation done using US or Canadian gallons to arrive at the mpg. Since Canadian gallons are about 1/5 larger in capacity it will make a difference. Canadian mpg's are higher than the US's when calculating from metric to the imperial system. If the calculation was done using US gallons, it will probably be close to or exceed Toyota's estimated Canadian highway mpg, which is 39. Either way, still pretty darn good.

    I cant wait to drive a trip and see what kind of mpg I get on the highway . I'm in TX also so A/C is mandatory and probably the main reason it is so low. I keep the A/C around 72 and my wife prefers 75.

    I see that a few people had good results with the paint protection film, and no negative testimonial yet.

    It seems that everybody had it done at dealers. I saw a do-it-yourself kit on E-bay dirt cheap. Bad idea, you think? :confuse:

    Eureeka. Groza found it. After an exhaustive search (okay, he did a Google, alright?), here is what several authoritative sites say about rotten egg smell:


    You can, but there are no real benefits, other than the gasoline manufacturers making more money off of you. When you use a fuel with a higher octane rating than your vehicle requires, you can send this unburned fuel into the emissions system. It can also collect in the catalytic converter. When you over stress any system, it can malfunction or not do what it was designed to do properly. In the early 90's, an early warning symptom was a rotten egg smell from the tailpipe. Easy fix, go back to using regular 87 octane gasoline. The rude odor usually disappears after several tanks of gasoline.

    If you watch the display you will see that the trip time resets itself to "0" each time you shut off the engine for a few minutes. The "mpg" resets itself each time you fill up the tank.
  • hey guys its been about a month since i ordered my blizzard limited from the dealer but that bad thing is the Mirrors dosent has the turn signals indicators :( so i asked about there prices in toyota parts and they are 400% each :o and they told me i'll need the assembles and do i my owen harness to let it work :( the goood thing my limited really got the POT light under the mirror but not the turn indicators :(

    any help or backup would be appreciated :)

    "I would think that when Toyota lists 31 MPG for highway it's based on the legal speed, I would assume they use 55 MPH, or is it 65 MPH?"

    just me: Good question. The guvment (EPA) dictates rules for Fuel Economy Test Driving Schedules. In West Virginny, we used to call them people revenoo-ers.

    Manufacturers perform the EPA tests on chassis dynamometers, not on the road; i.e., the cars are not "moving" in traffic - they're strapped down with the driven wheels turning a drum to load the engine. Here' what the EPA test schedules are:

    Distance 11 miles
    Time 31 minutes
    Avg speed 20 mph
    Top speed 56 mph
    Stops 23
    Idling time 18%
    Engine temp @ start Cold
    Ambient temp 68 to 86 F
    A/C off

    Distance 10 miles
    Time 12.5 minutes
    Avg speed 48 mph
    Top speed 60 mph
    Stops None
    Idling time None
    Engine temp @ start Warm
    Ambient temp 68 to 86 F
    A/C off

    Canadian test rules are more complicated, as they involve actual highway use, with Moose avoidance included. Groza doesn't have enough time to get into these.

    Is it 3M material? Personally, I wouldn't go with anything other than 3M; the company that applied mine told me they had to go through a 3M class and be certified on installation, before they could even get it. There is alot of stretching involved so there is a tight fit...if you're real good at do-it-yourself things, go for it; but I would make sure it's 3M.

    I have an XLS with the JBL system that I want to add XM radio to. I should have purchased it from Toyota but I didn't want the antenna on the trunk. After reading 3puttmax's posting at #5618 I called Toyota to see if they'd install it with the antenna inside the front windshield. The "accessory specialist" gave me the standard Toyota line about the antenna is designed to be on the outside of the car and that's the way their installer must install it. I told her that I'd seen a smaller antenna installed inside the windshield and she said she'd have to call her counterpart at XM radio before she could authorize Toyota to install it there. She called me back yesterday and said the XM rep said that the smaller antenna is recommended for the windshield install because of the slope of the windshield. The XM rep also stated that there shouldn't be any drop off in connectivity with the windshield install versus the trunk mounted install. So I ordered the smaller antenna from Circuit City (it's on sale for $23) and I'll take it to Toyota when they install my system next week.

    My wife and I are buying a 2005 Avalon XL that, if it drips water out the exhaust, will be something we will not be too concerned about, since my '93 Toyota truck (with 211,000) miles sometimes drips water when it is cold started in the winter during the first minute or two. OE exhaust lasted until 203,000 miles. This is on a vehicle that has traveled almost to the moon (which btw is 221,460 miles away, at its closest point!) :) Enjoy your Avalon - I miss the Cressida, but long live the Avalon!

    Well done. That antenna price is less than half what I paid. Don't forget you also need the Terk XM DUAL TO SINGLE SPLITTER (XMSP), as well as the XMICRO antenna, in order to connect to the Toyota XM receiver.

  • Hi Deanie,

    Thanks for your tips last week on removing any residue accumulated at the ends of the wiper blade travel. There was indeed a thin film there and I removed it, but the squeaky noises continued. Next time it rained I had a close look at the wiping motion from outside the car and saw that the bottom end of the driver's side wiper was chattering markedly during much of the motion, in addition to squeaking. The dealer has since replaced both blades, so far they are working OK.


  • Hi Deanie,

    Exactly as you guessed, I got my best-ever fuel economy reading during a period of several minutes of uninterrupted level highway driving at about 50-60 mph, immediately following a gas fill-up.

    I agree that it would be nice to have the option to switch between average mpg since the tank was filled, and instantaneous mpg. It is only a matter of software upgrade and one more switch.

    But I also share your feeling that constantly monitoring and trying to optimize fuel economy by keeping it under 2000 RPM or so gets boring. It sure takes away from full enjoyment of the car's potential. And as we all know, it's good for the engine to rev it up once in a while!

    A steep uphill is coming up ahead, so move over Dr. Jeckyll, let Mr. Hyde drive for a while...

    Thanks didn't know I'd need the splitter also.

    It may be difficult to put the antenna in the break light housing. I was trying to do this myself, and I gave up. Eventually, I placed the replacement antenna on the side of the rear console just below the back windshield. I have to problems with reception so far.

    I highly recommend the Terk mini antenna instead of the original one. The installation is easy, and it would be even easier if I didn't have have to remove the old antenna.

    Has anyone have an aftermarket remote start on their Avalon? I've read that many people were not happy with the original Toyota setup.

    Can you let me know which brand and model you have installed? My dealer was trying to install an after market remote start on my Avalon, but they gave up after 4 months, and gave me my money back.

  • Hi Petl,

    I used US gallons when I converted from liters/100 km to mpg.

    As you say, Canadian ("Imperial") gallons are 20% larger (about 4.5 liters, compared to 3.8 liters per US gallon). So, 36 mpUSg = 43 mpCIg ... which in fact exceeded the estimated 39 Canadian highway mpg.

    Now, since Canada went metric decades ago, I really don't understand why Transport Canada still asks car manufacturers to report fuel economy in both liters per 100 km AND miles per Imperial gallon. Wouldn't you agree that in Canada the Imperial gallon is an obsolete measure by now? Wouldn't it be more useful to rate fuel economy in liters per 100 km and in miles per US gallon, to allow consumers a more direct comparison with US performance figures?


  • I am reminded of what a specialty instruments salesman once told me:

    "stainless" means just that: stains LESS...!
