i get about 20.8 MPG mostly freeway miles. most of the time, i get up to around 320-350 miles before the gas light comes on.

I just took our 94 gs3 on our first road trip.
traveling around 75-85 MPH we got 405-430miles on a tank of gas.w/ a few of those with the light on.
much better than the 220-280 we get around town.

00 GS4 w/ 18" tranny in power mode always.

When I got the car new I drove it up from LA on one tank of gas
400 miles. about 22MPG.

Now I just do short runs mostly on cold engine a few times a week. By the time I get to my destination my water temp is just at middle.

I'm averaging about 200 to a tank in San Francisco. (lots of hills)
About 11MPG. car has 20,000 miles on it now.

If I do a combination of city and highway i get about 300 to a tank. about 17 MPG.
