#187 of 254 Re: Chevrolet Aveo: Real World MPG [c118fe] by veloraid Nov 26, 2007 (1:16 pm)
Replying to: c118fe (Nov 19, 2007 1:00 pm) Thought I'd put my 2 cents in which is about all I have left after filling up the tank, AGAIN! I'm in Canada and am getting not better than 11 and more often lately with winter starting 12.5 litres per 100 km or about 26 mpg. I also have started to drive like a granny but that sucks! I love the look but my Ford Focus wagon with a 2 litre did better mileage. I'm very frustrated with the car, can't get any straight answers from the dealer. How does a compact car with a 1.6 litre engine get such poor gas mileage? I'd say the tank was leaking but there's no smell and anyway it's new.
#188 of 254 My Average Gas Mileage and Best Ever... by tomwillett Nov 27, 2007 (12:37 am)
I have a 2007 Manual Aveo 4 Door Sedan. (Aveo LT). I usually get 31-34 MPG with mostly highway driving but I have gotten as high as 37 MPG once. The difference on my best MPG seemed to be speed (about 60MPH most times) and no need for air conditioning. I have 10,000 miles on the car and run Mobile One Extended Performance 5W-30 Synthetic. I am very happy with the vehicle. Replies to this message: veloraid (Nov 27, 2007 7:11 am) hammill (Jan 24, 2008 4:38 pm) hammill (Jan 24, 2008 4:43 pm)

Replying to: tomwillett (Nov 27, 2007 12:37 am) I'm using synthetic also. Doesn't seem to make a difference. And it's 5 speed. Most of my driving is city but I can't drive 60 mph on the highway! Anyway 31--34 mpg on the highway at 60 clicks is certainly nothing to write home about. I would get at least 37 on my old Honda Civic doing 70-75 mph on the highway. But take yours in traffic for a tank and you can just watch that gauge move. You won't believe it.

#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.
