We have about 10,000 miles on our LTZ/3.9L now, and the fuel mileage has stabilized to an average of around 27.5 MPG. about 85% of our driving is highway, and I have recorded 29.3 as the best, so far, holding steady at 68 MPH on the interstate. A few weeks ago, I let the car have a run coming across Kansas. Traffic was light, and I ran about 200 miles between 85 and 90, and got 26.5MPG. That is quite good, in my opinion, for that speed. Luckily, I had a guy in a BMW running about 1/2 mile ahead of me at that speed, and the cops finally got him just west of Salina. I stopped, gassed up, and came the rest of the way at the speed limit. The LTZ handles great at 90! |

| Back in the spring before I had to run the AC full blast in this 90-100 degree weather I was getting about 20-22 around town (LT2). This is a small town where you normally drive 30-45 mph and stop only at stop signs and lights. No bumper to bumper traffic, I'm now lucky to get 18. Really disappointing. I did lots better than this with my 3.1 litre Malibu. My Deville isn't much worse. I get around 15-16 with it. I guess the answer is to get a 4 cylinder Malibu. I'll do that next time or sell both the Caddy and the Impala and get one Avalon. That will save a lot of money and get better gas mileage than either car so says a friend with a new one. | |
Does anyone have any knowledge or know of any data posted on fuel consumption during idle? I was "forced" to wait an hour today with the engine idling. I hated doing it but had no choice. While I sat there and stewed, I wondered just how much fuel I was burning. If anyone has any idea, please pass along the info. I know consumption will vary by engine, possibly by other conditions such as temperature, AC use, etc. but I wanted to get an idea.

On straight highway driving I get 32 + a tenth or two, and 26 in town averaging about 28. I wanted to downsize from the minivan due to the gas prices (and with the middle east thing getting shakier again, it will go up some more.) Going 70 mpg drops it down to 28mpg. I am pleased with the mileage--after reading so many posts in edmunds, I was beginning to think that nothing but Toyotas and Hondas could get good gas mileage. I was brought up in a junk yard in Iowa, and learned to prefer Chevys, and I still do; they have usually served me VERY well over the years. This one is white with lots of pinks stripes and decals, so if you ever see one like that, please wave, as there probably aren't many out there with that color combo. zmartha

Replying to: zizith (Jul 13, 2006 3:01 pm) I have a new SS which has less than 1,700 miles on the odometer and am currently getting 31-32 miles per US gallon at a steady 60 mph on the highway. In the city the mileage is 17-18 mpg. These numbers are exactly in line or better than EPA estimates. The car is simply great and I could not be happier with it! |
