Anyone from Missouri? MPG problems inside

I know for sure its not the same gas as all the other states, simply because every state has different (stupid) laws on mixes, ethanol, etc etc. The 10 percent ethanol alone has to account for at least a little bit, as it has alot lower BTU than standard gas.

I just noticed it when I was in/around KC. While I was there I actually did a road trip to Cedar Point (who loves roller coasters? this guy! ) and between KC and St. Loui I got 43.something. I was amazed. I was also doing 60mph +/-5. Didn't feel like doing the mpg for the rest of the trip to Ohio, but I'm guessing the mileage you are getting is related to the way you drive. Acceleration, speed, etc.

i really think youre getting what the yaris gets on teh highway doing the speed youre doing

frig, i got 42mpg on my first tank, but a did a road trip at 45mph on back roads to do it

i consistently get 36mpg city in the summer and only about 38 or 40 on the higway....depending on how fast i go

i find the yaris is SUPER sensitive about mileage depending on the speed youre going....just the gearing and wind resistance.....at 70mph youre doing like 3400rpm in a 5spd....right?

no idea, I don't have a tach :( That's one of the main reasons I have been thinking of getting a scangauge, just to get a tach so I can be sure I am in DFCO.

Dropping your speed and going light on the gas is about the best thing you can do at this point, as well as pumping up your tires and installing a grill block.

I used to complain about getting between 34-37mpg while driving at around 70-80mph, and only once I dropped down to 60mph did I notice a significant difference in my MPG.

If I can drive 50mph on the California 110, I-5 and 405 during rush hour, which are some of the fastest-moving, most congested and aggressive roads on the US, I am sure you could drop your speed down a notch. The whole point of driving "well" and economically is being aware of what is occurring around you. Pay attention to those behind you and you should be fine.

The scanguage is no magical/miracle tool that would automatically give you 40 mpgs. It will only confirm the very thing you are trying to avoid-- which is slowing down. As for DFCO.... you have a 5 speed 08. As soon as you lift you foot off of the gas while in the highest gear, you are in DFCO ( gear appropriate for speed).

You really are asking for miracle if you expected 40mpgs running 70mph.

I can tell you it was hard for me to slow down at first, yes it was scary. I got used to it and now I run 55mph everywhere. The only time you'll find me break 60 is if I'm merging onto fast traffic.

Yes I have a scanguage. No, didn't need it to break 48 mpgs on the dealor tank of gas. I'm averaging 48 mpgs through the whole year.

And lastly, I do understand that I'm in SoCal with great weather, but 1/3 of my commute is early morning with temps at 50-60 degrees.

The thing that really confuses me is that even running 60 MPH on the highway, cruise on, I still only got 39.8~ MPG. I don't think the car could have been driven more conservatively in the city on that trip either. Hell, I even would shut off the engine on some of the really long straights and run with it in neutral (key on, engine off, for steering).

Lets say its all speed and not the fuel etc. Another 5 MPH on the highway should result in 5-8 MPG? I can't tell you how much I was babying the car, I mean people were getting MAD in the city I was accelerating so slowly, not to mention all the people on I-70 playing "speed racer" around me.

4 MPG, where are you in MO? if you are near the St. Louis region I would go for a ride with you and give you some pointers if you would like. I am not the best out there by any means, but I have averaged 42.7 in an automatic for the lifetime of the car (1.5 years, almost 22,000 miles)

oh, and with recent drops in gasoline prices, the E10 mandate could go by the wayside. MO state law only mandates the E10 blend when ethanol is cheaper than gasoline. this is no longer the case, I have not heard of any changes, but it could happen. (however if you live in the St. Louis metro, this won't help because we have required E10 for years to keep the air clean)

you'd probably be shocked at how much less MPG you get when the temp drops to below freezing

Im in columbia, mo. What speed do you average on the highway?

I just filled up (3.x gallons lol) of all city driving and I got 35.5x MPG... so I am acutally getting better MPG with all city driving than with city/highway mix.

Filling with such a small amount puts way too much importance on the consistency of the fill itself (ie, which way the car was parked - up or down angle, how sensitive the shut off was, any air in the filler/tank, temperature...etc.).

Cruise Control is bad for fuel economy. With the CC going the engine, in my opinion, overreacts hills. You'll get much better FE if you just try to keep the gas pedal in the same position most of the time. This is made very easy with the scangauge.
For all those who are unhappy with the fuel economy of the Yaris, if you saw the last episode of Top Gear, on their track they managed to get 17 mpg out of a Prius. They came to the conclusion that it is all about the way you drive.

lol..Yes, I totally believe you. Over here I've duct taped to the top grill and taken off the airbox snorkel.

I thought so, but apparently he has an affinity to terrible drivers and getting run over.
