I have the 5 spoke S model 15s and let me tell ya....I honestly think that they look too small....might.....just might.....look aight if you dropped the car 2 inches, but at stock height...small.

i imagine there would be some small improvements depending on how much lighter the wheels are compared to the stock steel wheels.

[Ron]

stock 14" steel wheels and the 175/65/14 tires weigh ~30lbs per corner... its not easy to get lighter than that without spending a lot of money.

my fuel economy has probably gone down ~20km/tank with fatter tires, heavier wheel/tire setup. time will tell, as i drive them some more and do more fillups

[spacemanoeuvres]

Fill up #3:

Took 11.350 gallons with the odometer on 398.

That's approx 35.1 (US) miles per gallon...blech, disappointing

Driving was 65/35 highway; frequently cruising at 80+ mph with the AC running about 20% of the city & hwy miles.

[foober]

My gas milage has gone down as well at 2000 miles on the car. Last fill up was 37 miles to the gallon. But I'm running the ac full time now. I've been doing alot of city driving as well.

[Chris07LB]

Current tank, 375 miles, with two fuel bars left. I have been getting over 400 miles out of every tank so far.

I drive at 70mph, for about and hour or so straight. I see only about 5 miles of city driving, once getting off the highway.

3 weeks old today, automatic / Liftback.

I found a product which has a lot of backup and testing and claims pretty fair fuel economy and performance for little money.

http://www.ecotekplc.com/

I am going to buy one at some point to try it.

[Tankota]

Consumer reports tested a ton of products like that, as well as a few other reports.. then did not find a single device or additive that improved anything, and in fact some of them made things worse. Don't belive everything on the internet..

As they pointed out, if there was an additive that could improve your milage or power like they claim, gas compainies would have added it long time ago.. just think - if one brand gas gave you more milage than another brand, they would be marketing and selling it like crazy, and people would buy it over another brand (and it wouldn't realy cost huge gas comanies anything to add the same stuff thats sold aftermarket).

[ECHOKnight2000]

Going along with what Tankota said, not only is it really a scam and if it did work others would jump on board namely the oil companies...also since gas has risen and its an "issue" at least in the U.S. cause we're spoiled brats but anyway you want to be weary about these things as I'm sure they will bank on our mentality of saving gas and doing whatever it takes including being desperate about it. I'm sure this is open season for these kinds of products since gas has risen, and you have to study or look at how they word things as well...like implying their product boosts a great deal amount when it might not...anyway you get the point.

[swng]

If so, I would wait until something gets some positive comments of Consumer Reports before I buy. Meanwhile, it would be useful if anyone who has been using such devices post his/her fuel economy numbers here.

[boxerboy]

First tank was 9.85 gals. 375 miles. 60% highway,AC on. 5spd hatch.

[swng]

My last tank has yielded 588.8 km out of 41.067 liters. This translates to approximately :
14.338 km/liter, or
6.975 liters/100 km, or
40.519 miles/gallon (Imp), or
33.766 miles/gallon (US).
The time ratio between city and highway driving was about 40/60 and the AC was on more than half of the time. Tire pressure - 34 psi all around.
Not bad for an auto .

[DVS YARIS]

last tank was on one flashing bar with 655 km so i havent been botherd calculating it but i am pretty happy with it :D
cheers curtis

I like how you think you are going to get 40mpg driving 25+ mph faster than how the EPA rates it.

Glad you like it

Seriously though, I was expecting a consistent 36/37 mpg out of the Yaris. Especially since my 93' Paseo (rated at 28/34) used to get 35/36 mpg driving exactly the same route/speeds.

I don't think that's unreasonable

I think the paseo is much more aerodynamic than the Yaris. It definitely looks more aerodynamic than the liftback.

Also gearing could come into play. But I think you would have closer numbers to what you expected if you had got the Yaris Sedan. The Paseo and the liftback are way different body designs.
