I'm getting around 21 in town and about 33 on the hwy, with gas here in NC at 190 a gallon, I sure enjoy the mileage the G6 gets, wonder if a K&N air filter and synthetic oil would improve on these numbers?
I am going on a 500 mile drive monday, I'll let everyone know how she does, I'm guessing arounf 32 hwy....and it's going to be nice and cold, so the heated seats will be really nice
