Roadrunner, could you describe exactly what type of driving you're doing; are you hypermiling; how fast do you drive? Your numbers look suspiciously high. Why do you fill up after only a couple of hundred miles sometimes? Why, when you did 50% highway, was your mileage worse? How are you figuring your mileage? Just curious; not accusing you of anything. It's just that on a recent trip with my 5sp, going 60-65 mph the whole time on 99% highway, the best I could get was 46.5%, which was great, in my opinion. I just find it hard to believe that on a car that promises 34 mpg city, you are getting in the upper 40s to 50 mpg.

Most of the miles on my Yaris are to and from work. My commute is 18.5 miles each way with 26 stop signs or traffic lights. My route is mostly rolling streets, and my commute is usually not at rush hour, but after it. My max speed is about 55 going down a long hill, otherwise it is 50 mph.
I am a hypermiler over at GasSavers.com, and have learned alot of tips. I do use a Scanguage II, a wonderful product, and worth its price.
Yes, my Yaris thinks it is a hybrid, for the mileage goes down on the highway.
The reason for that is going 60 to 65 mph, my mileage suffers, and there is nothing I can do, other than slow down, which is dangerous at times.
I use my trip odometer to show me miles driven, and the fuel pump to show me how many gallons I purchased, the rest is simple math, that is computed on GasSavers.com in the garage. This is my Yaris in the garage.

There are many reasons for my high mileage, and having a great route to and from work is a large reason, and so is driving off hours. I never use EOC, not for me.

The price of gas dipped down so I thought that I top off my tank even though it was only half empty. For 179.4 miles I used 4.004 gallons for a MPG of 44.8.

I just put synthetic in it and my tires are right at 40 psi. I'm slow to takeoff and utilizing DFCO where ever I can; other than that no special tricks!

It's kind of rough here in Michigan where the speed limit is 70 mph. It seems like I do so much better on the back roads where I can set the cruise at 55 mph. I want to bump the tires up to the 44 psi max and I'm considering blocking off some the space in the grill for better aerodynamics. I'm a little leary of shutting of the vehicle at any time where it is still moving. We're still taking this a little bit at a time.

It's an awesome little sedan at any rate.
