Not impressed with mpg!!!

[tuckevalastin]

junk?

[Mikeb Yaris]

I did an experiment intentionally NOT trying to get good mpg. Still got over 38. I'm always interested when I hear folks struggling around 30. Now that gas is cheaper again, maybe I'll do another experiment to see how hard I have to drive to get 30 mpg or worse.

I drive close to 30 miles to work each day and about half of that is going 70mph trying to keep up with traffic, sometimes I have to turn off the cruise control if by some chance people decide to go slower, besides that it's city driving with a bunch of stops, I'm getting about 33-34mpg, I get a bit better mpg if I go to Orlando, which means spending at least 30-40 minutes on I-4 driving at about 70mph. I accelerate very slow when leaving a red light and also coast down towards red lights. I just changed the oil about 2 weeks ago and that boosted my mpg by 2 mpg.

I was getting 36 with the jetta tdi I used to have, but the yaris is so much better..... and new.

Weird.
If your Swift can get 38 mpg, I would think Yaris can do similar.
I get 35 mpg from highway and city mixed about 50:50.

could be one of many of these things:

1. you weigh a lot, trust me the yaris can get shitty mileage if it has to be forced to drag a tubby person.
2. your carrying a lot of stuff in your yaris, take out that junk!
3. you jack rabbit... take it easy when you take off from a light
4. when the engine is cold, take it easy, it wont let you go into gears as easily and you could be loosing a lot of gas by forcing it to go fast in cold weather.
5. change your air filter... it helps.
6. make sure you have a good way to measure the mileage... I dont know how the others on here do it but I trip the meter when I fill up and as soon as it starts to blink thats the number I use. Once the blinker starts its consumed close to ten gallons... divide the total by ten.. pretty easy.
7. dont speed!!! take the slower route, it will be less stressful and cheeper!!


Those are the top SEVEN reasons that usually prevent (MY) yaris to loose fuel economy.

ps: I get 40mpg, with about 75% highway and 20% city and 5% being a kid and having fun LOL!

I weigh 104... Nothing in car (haven't even put the drivers' manuals in the glove box yet)... Am measuring from fill-up (when the pump clicks shut) to the first few miles after the fuel gauge starts blinking (I hit the first gas station then) and divide by 10.

Oh, well! Will hope that time takes care of it (have just 148 miles on it so far); thx.

Warranty! Have it checked out

[YAR1S]

It took me a few tanks to realize that you have to make an effort to get good miles... plus I used to drive a V8 Grand Marquis so It was a differnt drive and I literally only got 250 miles on the first tank.

It will hopefully just require time like you said... but if not then maybe get it looked at :(

i just drove 900 miles from NY to wisconsin..in cold weather..averging 70-80 miles an hour and averaged 40 mpg...i use 91 octane..<higher retards the timing>

When I fill up, I fill up before it blinks (when it has 2 out of so many in the gauge).
It's usually around 9 gallons.

Even if you're filling up only 9 gallons and still dividing by 10, it's still bad mpg.
More so, when your Swift could get 38 mpg...

Your commute is two miles? No wonder, your Yaris probably doesn't even warm up in that short distance. Buy yourself a bicycle and you'll get excellent "mileage!" I used to bike 8.5 miles each way to work on a full-suspension mountain bike, almost all year round and this was in Belgium! I would do the same here, but it is 22 miles and San Antonio is not conducive to bicycle commuting. But if I were only two miles from work, hell I'd walk there!

you want to divide the mileage traveled since last fill up by the number of gallons that you put in the car


so if you travel 300 miles and you put in 10 gallons then you have 30mpg

if you approximate that you used 10 gallons you are getting a inaccurate number.. could be off by 3-5mpg.. which makes a big difference..

Regarding #1, does having a pot belly qualifiy as being "tubby" ??
