Toyota Yaris fuel economy

I have auto/sedan. My city driving is in a town of 20,000 people, so a lot of stop and go driving. Stop signs every quarter mile or so. No merges or blending traffic like in a larger metro. It's also colder which means it's idled longer than normal. But still, 23 mpg is disappointing. It is under 3000 mile and I'm hoping for improvement upon break in. I do not mash it ever I coast as much as possible but I do keep up to the speed limit. Some people tell me their Corolla is getting better mileage.

Or their lying.

Ok, just put has and noticed Ive been running on low PSI on my front two tires the whole tank. BUT!
Previous tank was 32mpg, this tank was 33.1 MPG!!!!!!!

Now Im going to inflate the tires to like 43PSI instead of there maybe 26 there at now. And then I will see what happens this tank.

I am preparing to find some time to read all these articles. I know I may not agree to everything that they say, but I know I am going to enjoy every article immensely. I also know that I may be surprised by something that they say as I read on:

I doubt the gauge is this precise or this linear. At least I've never come across one that was.

There's one reasonably accurate way to measure fuel economy. Fill the tank. Drive. Fill the tank again (hopefully to the same point each time--two clicks with a few seconds in between is what I do). Divide miles driven by gallons used.

Some people might think this method is just common sense. But I've come across many people who estimate MPG based on the fuel gauge. Usually a bad idea.

Miles --- gal-- MPG
276.0-- 7.824-- 35
367.0-- 9.977-- 36
215.0-- 6.294-- 34
247.0-- 6.264-- 39

261.2-- 8.439-- 30

lol.. can you tell when i put on my rims/tires and took off the stock ones?
i've also started getting more relaxed driving a little faster... i guess i'll have to get back on the ball.

this is with no engine mods, 205/40/17 tires on enkei rims, custom woofer box in the back that probably weights 20-30 lbs

OUCH!.... I hate myself unless i get 40+mpg. Even when i've got some weight in the car and drive 80 I still manage 35+ mpg.

Whoa... With gas at $3 those wheels are costing you $200 per year, and driving faster is costing you another $200 per year.

landrym28 · 12-03-2008, 07:39 AM

I can usually crack the 40mpg mark in the summer, but in the winter, I'm usually in the 29-33mpg range. It's good that gas prices have decreased so far, as it kind of offsets the fact that I can't get as far on a tank.

TinyGiant · 12-03-2008, 11:16 AM

yeah I plan on starting to hypermile more again and keep it under 55 on the hwy

35 seems to be about the best i can get with the wheels .. but they make the car look so sporty.. lol i'm not going to get rid of them

with the money i'm saving since i got rid of my jeep 16-18mpg that $200 a year is nothing lol

voodoo22 · 12-03-2008, 11:35 AM

..and if you haven't taken the new tire size into account in your calculations, you can add another 1+% to your figures, because that's about how much further the odometer will read over actual with that new setup if you went from 15's. If you went from the stock 14's then you can double that difference to 2+%. It's not a lot, but it adds up by the end of the year.

TinyGiant · 12-03-2008, 11:45 AM

my spedometer is about 4mph higher than actual speed at about 50mph

TinyGiant · 12-03-2008, 11:45 AM

if i remember right

TinyGiant · 12-03-2008, 12:29 PM

it just dawned on me..

when the mpg started going south was when the weather started getting colder.. and i had to run the Defroster for the front windshield alot.. from what i was reading earlier the defroster runs the AC too... thats probably more likely the cause.. whenever i have the heat on its always on the defrost/footwell setting...

In my 2009 owner's manual, page 178 states that:
"If A/C is not pressed, the system will blow ambient temperature air or
heated air."
And then later on page 183, it states:
"When the outside air temperature approaches 32 F (0 C)
The air conditioning system may not operate even when A/C is pressed."

Perhaps that has changed from the 2007 or 2008 model year, as my buddy
who has a 2007 said that he thought the A/C came on automatically when
he moved the selector to the feet and windshield defroster setting.

Is that a definitive answer or not.

I have heard that other makes of cars use the A/C when in defrost, but who knows?
