Im just about through my first tank, and I only got about 17 MPG with some highway and soem city, not getting on it at all....

What kind of mileage are you getting and how many miles are on your car, i think mine just needs to be broken in, im only at 150 miles....

My g6 is currently at 1100 miles but I reset my fuel econ meter at 800. For that first 800, my meter read somewhere between 22-23 mpg. The vast majority of that was in town driving with speeds 35 mph and lower. I reset the meter at 800 miles because I was going on a 150 mile trip of highway driving and wanted to see what I would get on the hwy. For that trip the meter read just below 32 mpg.

I average about 19 in the city. On my 200+ mile highway treks I have gotten about 33 every time. These are according to the computer. I would say the actual values are somewhat lower. Over all I'm pleased with the fuel mileage, it is improved over my Grand Am GT.

5500 miles... 17 mixed highway/town driving..


Anyone notice the gas gauge is kinda strange when you are driving hard? Like its 'estimating' your fuel level?

Yea, when im Driving the gas gauge is always lower than when i put it in park, it really shifts around a lot, I think the fuel sensors arent too great.

Im used to floating gauges (my Z would slam you around in the seat and easily exert ~1G when pressed, parking on a hill, stopping hard, etc.. I know how it is 'normally').. this is much different. Its almost like its 'estimating' how much fuel you have??? Hard to explain.
