2005 Cobalt 42-44 mpg consistent
We drive 67 mile commute LA county; recently replaced one tire and this week our average entire week is 44.0 mpg, previous weeks was coming in more like 42. We still plan to replace plugs and wires, buy KN filter, and replace all four tires in a few months with Michelin Eagle or something equivalent or better. Anyone with tire experience we would like to hear about what gets the best mileage, and what inflation you run at. We coast about six miles continuously at one point every day...but if you are thinking, we climb the same hill going home so it averages out over time. Stop lights still our worst enemy, we make some and miss some and usually in traffic so cannot always time the takeoff and avoid stopping.
But with two drivers and commute traffic both ways, a car rated about 30 is doing pretty well in my book. Internal car gauge is confirmed by actual gas purchases to be within 1 mpg of accurate.
