Fuel Efficiency and the Yaris

[Yaris Blue]

After four and a half years I finally made it to 50 MPG. 104 fill ups... 41,331 total miles... 824.68 total gallons. 50.1 MPG!

Incredible! My overall average is probably right at 40, or perhaps a bit above. I don't even have one tank at 50!

With DFCO and P&G extended time on all freeway i can get 48-52. depending on the terrain.

I am just learning some of these techniques using the Scangauge II and changing driving habits. I think its funny becuase I have been able to reach 45 MPG TRP AVG in heavy stop and go traffic but only 35 TRP AVG in free flowing traffic conditions.

Wow. my best tank = a hare under 49 MPG from Winnemucca, NV to Mill Valley --- I-80 to Hwy 37 to 101.

yeah, even though my lifetime average is over 43, I have never gotten 50 on a tank (probably 49.2 or somewhere around there on a flat trip of 45-60 mph). I believe if I employed hypermiling techniques it would be very doable

[why?]

I just had a tank that was 49.9, and fuelly averaged it up to 50. It was 49.989 or something like that. New tires are wonderful for gas mileage, and no dfco at all. Just neutral coasting and some turn the engine off at red lights.

What a shock, tires make a huge difference.

I just drove from Seattle WA to Sacramento CA and only averaged 34.79 with a high of 40.09 getting 421.3 miles on 10.51 gallons, thought I was going to run out of fuel at that point. I was hoping I could average closer to 40mpg but it was hard to maintain lower speeds, I drove average 70 mph.

I think weight played a big part of it, my cousin was with me and he is a big guy, so am I, I weigh in at 250 and he is 270, other than that we didn't have much stuff.

Interstate driving is not the best for Yaris gas mileage. I do much better at 45-50 mph. Cooler weather is making it harder now.

Yes, I've also noticed a substantial drop in mpg due to lower temperatures (as expected). In the dead of winter, my mpg probably drops 20-25% over summer mpg. (I do believe winter blend has an effect, too.)

Most likely you have the winter blend as well . It started the beginning of October here .

I am fresh driver, have yaris for a year, at open road, not free-way, made one trip, about 300 miles, and cpu show 56 mpg, but real mpg was 50 mpg. And in past year I made 6000 miles.

. Which model year is your Yaris?

[Amdkt7]

Since my driving has returned to near normal I am averaging 43 per tank in the summer, and 41 MPG per tank in the winter. The best roads are still the ones where I can drive 40-45 MPH and have lots of opportunities to coast. The engine is more efficient under load, doing work, not at a light cruise. Hence the pulse and glide technique. Hilly terrain creates a natural pulse and glide, provided that you either coast, or you take your foot all the way off the gas while still in gear going down steep hills. I love the ride down off the mountain coming back from Chattanooga, I can stay in gear much of the way and watch the Scan Guage read 9999, and see the average mpg soar!

Hi guys, I have a yaris 2007 1.0L (Japanese version). I drive it here in Karachi in heavy traffic with high stop and go frequency. i am getting 26 mpg only while i am reading 40 MPGs or above in this thread.

Is my mpg fine or is there something wrong with my car.

[IllusionX]

It's about right for stop and go traffic. I get about the same with my 1.5L in city only driving.

My worst tank (all city) re my '07 = above 32 MPG, but I still agree with you. I made a trip to The Galleria (the 8th largest shopping mall in the U.S.) in Uptown Houston a day or two after Christmas. Big mistake. The specifics of the traffic jam I experienced made it impractical to turn the engine off at all. Before that trip, I was way ahead of my previous tank re fuel economy. After that trip...no way.
