I didn't measure the MPG at refuels, but the computer says "7 liters per 100 km" when I'm doing 110-115 KM/H on Hwy 401.

Translation from Canadian English:

"... the computer says "34 MPG" when I'm doing 68.3 to 71.4 MPH on the Interstate".

This is on a 2008 Sport 2.4 L with a K&N air intake, GE Performance exhaust, and a vortech cyclone ring in the air intake.

2008 Cobalt Sport 2.4L: K&N 69-4517TTK Typhoon Air Intake system; GM Performance Cat-back exhaust system; GM extrude honed exhaust manifold; Jet Powr-Flo Mass Air Sensor; AirTabs; Trifecta ECM tuning. Next project: wrap up the exhaust manifold

I've owned my 09 Sedan Lt auto for about less than a month and I've gone through 3 full tanks of gas. My average mileage 21, 18, and 22. This was according to my computer and verified by the good old fashion division (I was impress by the accuracy of the computer.) I live in Hawaii and my commute consist of mostly city driving, and most of my highway trips are up and down a mountain. My average speed has not been reset since I got the car and presently reads 16 mph.

These numbers really made me wish I searched more dealerships around the state for the 5-speed I really wanted, considering the 2002 Neon 5-speed this car replace was averaging around 28mpg under the same conditions. But I've been able to justify my auto by knowing that I would not be able to have my factory remote start with out it.

I'm curious to see the average speed if available to accompany some of your guy's numbers. It may help to put things into perspective.

Hey all,

I recently bought a red '08, 5 speed, 2dr coupe with 6K on it. Love it so far! I've run 4 tanks of gas through it so far. I shift up quickly, when possible, and drive pretty easy. I reset the avg mpg at each fill up and the trip mileage. Running down the road the instant mpg is interesting and varies to very high (99) to very low (13). Like I said it's interesting, but not very useful. There is a lot of difference between coasting onto an exit ramp or going up a steep long hill in terms of gas consumption. What matters to me is the average mpg. At the last fill up the dashboard computer said my average over 279 miles was 36.8 and my "divide the miles by gas bought" old style calculator method I came up with 37.5. I'm calling it 35-36 mpg. I really like the site.
