HELP..I got one of the 2009 Aveo5’s that gives only 18-22 mpg on average. Highway 24 mpg is a mechanical problem in my book for an Aveo. Chevrolet Customer service says my local garage has the technical ability to take care of it. My local garage seems to think I ride the brake, etc. It’s my fault. The computer says all is OK, according to them. A faulty part, wrong computer or program of something has to be wrong, but what. ????? :

Replying to: norm116 (Sep 14, 2009 3:53 pm) Once I got 27mpg on a tank and decided it was bad gas. If you always use a discount gas, you might try a couple tanks of BP. Some simple checks: Check your oil - is it dirty. If so, change it and the filter and try Mobile 1 (Make sure you use the proper weight oil (5W-30 I think. If you drive dirt roads - change the air filter. Check your brake fluid - might be some trapped pressure that is causing your brakes to drag. Feel the front wheels right after driving it - are they hot? Is there grime on the front wheels (signs of excessive brake drag). Lift up on the break peddle while driving on a level road and see if you feel the car gliding along any better. The garage may be right about brake drag being your issue, but it might not be caused by a heavy brake foot. You'll have their opinion, now you need to figure it out yourself. Hope this helps. |

| Good suggestions, but have tried all of them. I had the garage check for emergency and wheel brake drag. Tried different gas stations, with and without ethel, etc. Reading the previous entries I have come to the conclusion that there is a small percentage that have the low mpg problem and GM hasn't addressed it. Take a look at #1 of 6 My 09 Aveo Nightmare.. Poor guy, I hope mine doesn't turn out that way.. | |

My 06 Pontiac Wave (automatic) gives 15 kms per litre on the freeway. (roughly 35.5 mpg). 65-75 miles speed. For mixed City-highway driving, I consistently get 11.5 kms per litre. (27 MPG). This is with thrifty use of the airconditioner. I use the heater almost all the time in the winter. I know that the mileage will fall when I do. - sandyr.

My 09 Aveo5 is Auto with Alum. wheels. Is it possible that my poor gas mileage could be do to larger dia. mounted tires giveing an adometer miss calculation. I read on an earlier posting that a TSB said odometer might be off 7 to 9%. Might the basic models have smaller diameter wheels and the computer is not set to compinsate. Is such info. out on 09's. This weekend I am going to check against the ionterstate mile posts. Norm

Replying to: nav7090 (Jan 18, 2009 9:33 pm) I bought for 9200 also. That was in 07. I actually saw in the paper when the Eco was it's worst, a local dealer selling new for 7000. I have a 5 speed, and like it alot. Notice I didn't say love it? The gas mileage is great? Abt 32 or a little better under 55 mph. On the highway, not so good. 65-70 abt 25 or little better. The plus: Great gas mileage Flop down rear seats(you can fit a lot of stuff in through the trunk Quick and responsive little motor (1.6) Can carry 4 fine, 5 if you have to, but it can be done. The minus: This car should not, and I repeat NOT be driven on the Highway in the winter. NO,NO,NO. Do not. The chassis is a poor design in relation to the front drive wheel. The chassis is stiff, (the short length of car) and cannot respond to the powerfull front wheel torque, and that makes the tire want to spin in response to the engine. At highway speeds this is a disaster waiting to come about. The first sign of no traction (ICE) and you have the spinning event of your life. Big, and not so big trucks when they pass have a tendency to want to draw your vehicle into them. (talk about white knuckles-oh yeah!) Thank you for your listen. It is overall still a good little car. |
