#192 of 254 Winter gas by timseh Jan 25, 2008 (4:50 pm)
For what it's worth, I've gotten pretty lousy mileage in the winter here in North-East Ohio for a number of years now thanks to the government mandated fuel blends they force on us.   I haven't even managed to go through an entire tank of gas yet (I home office, so don't put a lot of miles on) in the two weeks I've had my 5 speed LS sedan, but based on the fill I did at half a tank a week ago and the gas gauge since then vs. the miles I've driven, it looks like I'm doing pretty good.   I'll be taking a road trip in the spring and it will be interesting to see if my mileage follows the same pattern I saw with my last car. Once I get out of the state going South, the mileage improves with the gas sold there.
#193 of 254 Better now by sun44 Jan 25, 2008 (5:00 pm)
I've gotten better gas mileage, since I got up to 5,000 miles. I average about 21 inner city. But on my trip, I was getting 34.5 mpg, but I didn't run the A/C that much. I think the A/C pulls it down bad. I hope they can fix that on the future cars for people..

Replying to: sun44 (Jan 25, 2008 5:00 pm) The Aveo is a descent car especially for the price. I see GM has said the 2008 model will have a 5 hp boost and expected 8% boost in mpg. That is good news for buyers. I wonder if they just tweaked the fuel injection?   I also find it interesting that a larger Chevy Cobalt frequently from what I read here and in magazines consistantly gets better mileage than the Aveo in both city and highway and the Toyota Corolla gets better mileage than the tiny weird looking Yaris as well. Something is wrong here. Replies to this message: wave54 (Jan 27, 2008 12:43 pm) poncho167 (Jan 28, 2008 5:49 am)

Replying to: poncho167 (Jan 26, 2008 5:09 am) Sometimes a larger, more powerful engine can produce better mileage because it's loafing on the highway and can get by with a more economical final-drive ratio. The 1.6L works too hard to accelerate from a stop and climb hills.   It all depends on the car, but it's not impossible that the Aveo could get better mileage with a 1.8-2.0L that has 25 extra horsepower.

Replying to: wave54 (Jan 27, 2008 12:43 pm) The city mileage is comparable between these cars as well.
#197 of 254 Early observation by timseh Feb 01, 2008 (7:55 pm)
I've only got 600 miles on my 08 LS Sedan (5 spd), so I know it's very early to be paying too much attention to my mileage. I did manage to burn off just over half a tank in mostly (85%) highway driving this week, though and decided to fill the tank tonight and see how I'm doing.   Just a hair shy of 35 MPG. I'm pretty happy with that, especially given the rotten mileage I've traditionally gotten in the winter here in Cleveland thanks to "winter gas".
#198 of 254 Only 25 mpg by intexas2 Feb 07, 2008 (9:33 pm)
New 07 Aveo5 with manual tranny. First fill up--only about 25 mpg. I'm disappointed. My 11 year old Geo Metro got around 35.   From what i can tell, the gearing on the manual transmission is the big culprit. I'm doing 60 mph and the engine is turning around 3K rpm. I keep wanting to shift into a higher gear, but, alas, there isn't one. My Metro seemed to cruise the highway at less than 2.5K, and that on a three-cylinder engine.   Why do they gear the 5th gear so low?   Replies to this message: poncho167 (Feb 08, 2008 6:16 am)

Replying to: intexas2 (Feb 07, 2008 9:33 pm) Better low end acceleration.
