To my ear it still sounds like it's stressing, but like I said, not too experienced with cars/mechanical stuff.

First off I'm glad you figured out the "glitch" the car was having... the loose nuts behind the wheel... J/K.... and yes there are 2 different formulas of gas for different temp. ranges.... just like diesel you need to put an additive in it in the winter they add something else to regular fuel also which causes a drop in MPG (can't for the life of me remember what it is) it's a heavier mix in the colder regions and the gas actually smells different.. if I'm not mistaken when they started it it was called oxygenated gas but have since renamed it.... I notice a difference between Rhode island and nj gas consistently.. I drive back and forth all the time only 3 1/2 hours but always a 2-3 miles per gallon difference at least with better mpg from NJ gas no matter where I purchase the gas, or how I drive... Must be a new england thing to add more to the fuel then in NJ

Just found a quick descrition of the difference in gasses if you really want to know..... and it has all the names I couldn't remember

In fact, I normally drive 5 mph OVER the speed limit, I just take my time getting up to that speed.

I really think that you are as much or more of a hypermiler as I am, you just don't want to associate yourself with the hardcore hypermilers. (not that I really blame you)

So now taking your time to get up to speed makes you a hypermiler?

That article's dated. MTBE has been gone from the U.S. gasoline supply for 4 years. It's not so much the oxygenated additives as the "distillation curve" that differentiates the winter and summer gas. Lighter, more volatile hydrocarbons in winter, heavier, less volatile ones in summer.

Argumentative much?

k so i'm still trying to catch up with the times..... I miss leaded gas ok...lol never a problem with that....

Except for brain damge.

refilled new 2010 3 door with automatic yesterday and it only got 32.86 miles to gallon thanks to temps between < 10 to 15 above . We use studded tires filled near 36 p.s.i.. Checked tires early noon and tires dropped to about 33 p.s.i.. The average temp was around 20 . The ECO-METER read 33.3 . There were times when needed to let car warm up to defrost windows . Seems like the ECO-METER doesn't take account for all the gas used when idling .

Yea but that dosen't count..... LOL You have to know I was kidding about that, but In racecars until about 5 years ago still used lead additive...... I'm gonna die of something might as well be something fun... But all those cars are gone now.....

[why?]

a bunch of people on this forum are so sensitive to gas mileage that they use common hypermiling techiques without even realizing it. It has just become their," old driving habits."

Loren always has good advice, and it really does become a game. Even people like myself, who don't go all out crazy with gas mileage, still use more than a few of them without really thinking. From not revving about 2000 rpms, to accelerating as slow as possible, and keeping the car in gear coasting as much as possible to use DFCO. My second tank of gas, when I was trying to get great gas mileage because gas was over $4 a gallon, I achieved 44 mpg. I usually get around 38 mpg now, "without trying." I say that knowing the way I drive is nowhere near normal.

Getting great gas mileage is a learned skill, and takes time and dedication, like anything else worth learning.

Matching the EPA's numbers means you are getting good mileage. Most people don't even do that.

I've only reached 41MPG once I never go over 30MPG
Why?
-90% city
-Lots lots of hills
-Always stop and go traffic
-Average temp 85-90*F
-I drive it like I stole it

And I still love my Yaris even when I get that horrible MPG. Why?
-Mom: FJ Cruiser ---> Gas sucking thing
-Dad: BMW 645 ---> 21 on higway / BMW Z3 ---> 8-10MPG <---

And I still get to rub in their faces that "I drive a slightly modified +/-30MPG car"

Actually your temp of 85-90 is helping your mpg.

I just got my Yaris a few days ago, a 2008 Yaris 3dr HB auto and on my first real fill-up, I averaged 33.75 MPG. I'm not new to hypermiling but there was still a big difference going from my 95 Civic to the Yaris. When I was driving the Civic which was rated for 26 MPG, I averaged 33 MPG.

Most of the "professional" reviews I read claimed the Yaris was slow but it felt faster than my Civic which has more HP and torque, especially going uphill. I'm still getting used to the accelerator since all the newer cars have a more sensitive gas pedal than my aging Civic. I don't recall seeing an RPM readout unless people are just using their scangauge. The automatic shifting is also more distinct but I'm gradually getting used to it. I commute over 500 miles a week, so I'll get used to it fast. :)

I see an awful lot of discussion of "winter gas". But winter formulations average only about 1.7% lower in BTU content than summer. In fact, the variations within different winter and different summer formulations is *greater* than the difference between average winter and summer formulations.

The fact of the matter is that cold weather kills fuel economy, for obvious reasons.

At AT sedan with P185/60/15 tires, the standard 4.29:1 final drive, and the standard 0.7:1 4th gear overdrive ratio, turns right at 3400 RPM at 80 mph. Which is still pretty low for a little 1.5L engine. Even the monster 500 cubic inch push rod V8 in the 1976 Cadillac from America's glory days turned 2700 RPM at 80 MPH. That's only 20% lower than the Yaris.

Even more impressive, when called upon, the Yaris' little 1.5L produces over half the power that the old 500 (8.2L) could. That's over 3x the power per litre displacement... and without any sort of turbocharging.
