i was hardly accelerating at all. i let go of the gass...i turn of my music, tap it, whirrrrrrrrrrr,

i quickly feel the automatic clutch, its in drive, i pop on the light to confirm, not in neutral, not in third, in drive, i check the parking break, its fine, i tap the gas, whirrrrr

i start to pull over and tap it one more time and its smooth as butter, regular deep voice of automatic transmissions shifting gears. no problems the rest of the night.

I suppose what ever has caused my drastic decrease in mpg all the way down to 25 all highway driving at average 65mph is also causing this problem. Anybody have any ideas what is wrong before i head of to the shop on monday let me know.

I really couldn't tell you, the "whirrr" I assume is from the engine not the tranny?

Since you said the car is still cool, it doesn't shift into the overdrive gear (4th) but once the engine warms up or gets to "normal" opperating temps it shift, that's if you have an automactic but otherwise I don't know, I'm just guessing. Hope its nothing too serious.

i hear it too on acceleration.. it didnt sound good at all sound like the timing was too advance...need to be retarded.. anyone had the same experience!! anybody..?? it could be the break in period... how many clicks you got on the car??

On monday I finally broke the 50mpg barrier! I'm soooo happy! YAY! I was surprised! Damn I love my car!

BailOut · 04-25-2007, 01:38 AM

Congratulations, ECHOKnight2000! That's awesome!

I haven't quite hit 50 myself yet. 49.74, but not 50. hehe

Thanks BailOut! Yeah its quite nice. Its funny how the before I thought low 40's was great but now anything at that point I'm disapointed! As long as its mid 40s and above I'm fine! Don't worry you should hit 50mpg.

nsmitchell: Shhhhhhh, don't tell them my secret!

Its nice to get hybrid mileage at an entry level price. What's even more amazing its a gas engine and not a diesel yea I know diesel can get more but its still impressive and not only with me but with you guys that have the Yaris as well!

marcus · 05-07-2007, 07:23 PM

hes drivin an echo ..lighter as well..it would be easier for him to reach it..but im sure its doable.. u just need... .26 m/gal...to hit it.. daym you should have rolled in down the hill..

Great MPG!!! Did you slip a hybrid system in there or something?! hehe

trini_per4mance · 08-15-2007, 10:37 AM

I get about 50mpg@70mph on the highway. This is way better than any Hybrid or Smartcar and it's way cheaper too. And, oh, I forgot to mention, way more fun to drive.

Wow at 70mph? I got 50mpg doing 65 I figured any higher I wouldn't get that great of mileage...I guess it depends on how far you're driving. If its a short highway trip I highly doubt it would be that high but congrats on the mileage, that's cool! It feels good doesn't it?

Well I bet you would get 70 mpg driving 50 mph

sanchez · 11-07-2006, 09:20 AM

my yaris with the way i drive( undernormal conditions) can get me at least 370 miles on a full tank

swng · 11-09-2006, 01:50 AM

370 miles = 590+ km. Not bad

!

palsan · 11-09-2006, 09:30 AM

The owner's manual suggests filling up when the tank is down to about one quarter. When I got the car a month ago and I read that I thought

- visits to the gas station more than once a week, that sucks

HOWEVER ... I do about 450kms a week and three quarters of a tank are plenty for that!

Filled up yesterday for the first time since installing winter tires: 497.3Km, 34.78L or 6.99L/100

I can keep filling up on Tuesday or Thursday nights (the cheapest times to buy gas in Toronto) every week and still keep more than a quarter tank

Here is a free tool to help estimate annual fuel costs:

Enjoy!

You are welcome and good luck!
BMGYaris' advice makes lot of sense to me. I admire the meticulous calculations.
In my layman's language, all bars do not necessarily represent the same amout of fuel and hence mileage. Depending on how full the tank is filled up, the first bar usually represents anything from more to a lot more fuel than the others. Trying to estimate a car's fuel economy with the data collected from just one bar can lead to a rather unreliable result. The bigger is the database, the better.
Long term averaging and consistency in filling up location(s) and method (I would say) can help minimize the effects of many possible errors.
Good research friends

keesue · 11-14-2006, 10:41 PM

Very first tankful = 35.6 miles/gallon

swng · 11-15-2006, 06:25 PM

The result is quite good keesue, considering that it's your first tank and that winter has arrived (weather should not be severe in San Francisco right now though). I presume you are reporting in miles per US gallon. That will be more than 42.5 miles per Imperial gallon.
Please keep on posting your results from time to time and describe your driving style and the traffic and load conditions leading to your results every now and then if you don't mind.
Thanks!
