Ok, just got to the end of a tankful today. It took me almost two weeks! My results -- 401 miles on 9.89 gallons, for 40.54 MPG average. The car has 1400 miles on it and I've been filling it with Cumbersome Farms gas. Guess I can't complain, and this thing is growing on me. It reminds me of my first new car -- a 1984 Dodge Omni GLH. Except, adjusted for inflation -- the Omni cost $8500, it's no contest, and the Omni was a dedicated performance car. It had a 2.2 liter motor and made just 6 more HP than the Yaris. I've even got a sway bar going on this weekend.

Had the Yaris for a several weeks now. Four fillups:
 
1. 40.9
2. 40.7
3. 38.8
4. 40.1
 
 #3 has the most around town driving, though not more than 20%. All others were 90% two lane highway commute (110 mile round trip) with typical occasional slow downs. I am not what I would consider a hypermiler. Drive pretty normal.
 
Very content with the car as a whole and the mpg I am getting.

Automatic or stick shift? Heavy, light, or no use of aircon? Those are superb numbers. I am guessing you have a stick shift, used the aircon lightly, and didn't drive over 70 mph.

You know, instead of an HOV lane. They should make a lane for those who want to go the speed limit. That way, nobody can gripe at you. It's amazing how much your mileage improves if you just keep it at 65.

That is a wonderful idea! A "Special Lane" for those wishing to go no faster than the posted limit!
 
Problem is that there would still be those that think the speed limit is too slow, even in that special lane.
 
Posted speed limits are the Maximum allowed by law. The only way to get a lot of drivers to believe that, is to impose on both their money and their time, As per post 377.
 
Personally, On the freeways, I get in the RH lane and do 65. Lately I'm finding that I'm actually passing more and more "slower'"cars, and 18 wheelers. Those that wish to go faster have 1-5 lanes to the left of me to "do their thing". On local and back roads I typically exceed the limit by 5 mph. If traffic begins stacking up behind me I will pull over and let them go by.
 
I have no problem with those that wish to "Go Fast". I do have a problem when they want to infringe on my space.
 
Going along with your idea; maybe a "DOUBLE" fine for those exceeding the posted limits in the "Special Lane" would work.
 
There will always be emergencies where folks really need to go faster.

Manual transmission. Use of aircon as needed. No deliberate intent to not use, but it is not on all the time I drive. Yes, probably very little driving over 70. I am not necessarily opposed to driving over 70, but in the Yaris, it seems like 65-70 feels fast enough for comfort.

2nd tankful, a carbon copy of the first 40.5 MPG. This time, however, measuring 1/8 tank intervals, I measured a low of 33 MPG and a high of 45, all combined driving. I'm going to change my commute a little when I get back to work and do highway on the way home and see what that does. I don't think I'd be surprised to see 45 MPG average.

What do you mean "measuring 1/8 tank intervals"? If you mean the miles driven between each notch on the digital gas gauge, those notches are not very reliable. I can go almost 90 miles before the first notch is gone and then each succeeding notch is less and less miles (regardless of whether I am doing all highway or not).
 
Only way to ever know milage is gallons to fill divided by miles driven since last fill.

Hmmm
 
My car is different than yours. I've been seeing consistent results measuring the 1/8th's. I still use the full tanks method, but in a Yaris, there's not much else to do than watch the fuel gauge, so I'm watching fuel economy via the 1.8th tank intervals as well.

What most people are unaware of, is the fact that when it comes to Toyota's or Honda's they have very efficient A/C compressors which take next to nothing to power. Therefore the use of A/C has very little effect on fuel economy.
Far too many people are thinking about the old days with big power draining compressors. Today that is a myth. I use the A/C all day every day as its 110 degrees average this time of year, so A/C is a must. I know how to calculate fuel mileage exactly and I tested in the spring before the super hot weather and each tank varied a bit as is normal because the terrain and route is always changing for me. The mileage with AC off 80% freeway, was 39.12mpg. With the AC on it was 39.85mpg . So as you can see the differnce in this particular case of two full tanks used as test points I did not suffer any loss. Now test 2. Same ratio 80% freeway but my southern route which is different and involves a bit of climbing.
AC off 38.8, AC on 37.9, so again, the difference is negligible.
