full tank i get around 100 something miles... mostly city.. but somethings wrong with my G..

dam guys. I prob run around 50/50 and i get around 260-300. I cant even image gettin close to 400 miles with a tank...i wouldnt mind tho

I'd say very wrong, lol........ I'd say your leaking gas!!

yeah i do about 70% city and 30% highway, and usually get 320 miles untill i fill up. when i fuill it i put in 17 gallons usually

well all these MPG's that are in the 300's or even 400's give me hope! But why do you guys think it varies so much? Does it really make such a difference the way you drive?

i think its all in the way you drive it
reset the ECU and change your driving habits for one tank and see wat you can get

I REALLY think running the AC really hurts the MPGs. This is true for all cars, but I think it's especially true for this car. When I hit the Auto Econ button, it always turns on my AC...even when it's 50-degrees outside and I have the temperature inside set at 78-degrees. If I run my AC, I know my MPGs will drop to 300 miles per tank or less.

i get like 220 to 230 miles b4 i have to push it.
but almost all city. and i am not a grandmother. so yah

468 miles with a tank on 95% highway, 3 gallons remaining

We're not talking about your Prius man lol..

Well I don't own the G anymore, but I did 350 miles every tank and fill up around 14-16gl (my fuel gauge was bad). On the A6 I can do close to 500 miles (21gl tank) and average is 27-32mpg if doing consistently at 65-70mph. My boss Prius can do 500 miles before re-fueled (70% city / 30% hwy). Hybrid is nice, but only if you do city a lot.

I drive 70% highway, 30% city through Houston. I generally get around 380-400 before the gas light comes one and I generally average around 24mpg. I always drive with AC on Auto Econ. Use cruise control if/when at all possible in Houston traffic. Driving speed is usually 70-75. The only "mod" I have at the moment is a K&N filter.

15-17mpg here according to the NAVI. 06 6mt bone stock. 60/40 city/hwy

Have no idea how anyone is getting 24mpg. That better mileage than a Honda Civic.

^ easy on the throttle and taking off slowly.

Just got just under 400 miles on my last tank.
