When I first brought (or still leasing yet.) it was calculating 27 mpg at the first 105 miles on the car. When I used to live in PA, my cobalt was getting about 31. Temporary living in VA, as my car was getting 34 mpg. Then, recently about a month ago, my car was still getting 34 consistent. Until, last Wednesday, My cobalt LS dropped to 29.3. Can't fiqure out why. Guess, no mpg is accurate on cobalts sensor systems. My manager from work, told me and old fashion trick to know for sure exactly what your car mpg aveage. He told me, just to first, fill up your tank, reset your trip A and Trip B miles. Then, keep track of all your miles, and when it's time to fill up. Check your miles and divide that from how many gallons your car holds. He said, that will be your most accurate. Of course, it all depends on how fast you drive, tires psi set at, and other misc... I haven't tried it yet but, this coming week on Tuesday thru Sunday, I will. Next week, I'm driving back up to PA on a 443.5 miles trip (about 8 hrs.) Is there any other tricks to use?

Replying to: pa356228 (Oct 03, 2009 12:43 am) you could use a super-precision scale to weigh the car, drive a certain distance, then measure its exact weight again. no stopping for burgers or a caf-pow or shopping or hitchikers or rest-areas. the change in weight divided by 9 lbs would be the # of gallons used. then divide that into the distance in miles and you have mpg. |

When I arrived here in Pittsburgh from Virginia Beach, My Cobalt LS mpg reach back to normal 35.4. Two days ago, it fell to 32.5. Did notice the difference BTU's. Guess, they figure no one will want to drive in the winter, besides to get what is necessary. So, no one will care about the mpg. Crazy world we live in. I'll keep updating now and then, so be patience. Sure feels great to be back home officially. See ya later...

Replying to: cobaltken1 (Oct 17, 2009 5:42 am) I bought a used Cobalt 07 with 23000 miles last Friday. I got the oil changed on Monday, and the air filter replaced as well. It is giving me 24 mpg in the city of Houston, which involves many miles of slow traffic and also a few miles of freeway., I don;t understand what I would have to do to get the mileage to a similiar value as you guys are getting, close to 30. ?? Any ideas? |

Replying to: houstonrice (Oct 29, 2009 4:26 pm) 24 mpg is the computer readout. I hope you have some good suggestions.

Replying to: houstonrice (Oct 29, 2009 4:29 pm) If you only drive short trips that have a lot of stop and go traffic, then 24 MPG is probably pretty good. The only way to really improve is to be light on the gas and better predict the traffic ahead of you so you don't have to use the brakes too much. Accelerating from 0 or very low speeds is what really kills the fuel economy. Try to keep a constant speed. I find that I get the best MPG between 50 to 60 MPH. 65 is not too bad, but not optimal. My auto equipped 08 is rated 22 City and 32 Hwy so I'm getting exactly what's advertised. |
