I know I was watching top gear once, and Clarkson said some cars' fuel injectors completely shut off when you're coasting down a hill in gear. Your wheels are turning your transmission which cause your motor to be at that RPM, so there's no need for the fuel to keep it running. 
Dunno if it's true though, can someone prove it?
Dunno if it's true though, can someone prove it?When I coast downhill at idle in my GX470 in Drive, it shows about 50 or so MPG. When I put it in 4th gear and the car is "engine braking" down the hill, it goes to 99.9+ MPG and maxes out on the dial.
did you read the last SCC best car shooutout?
they had an STi on there making 500+ HP and when they ran the mileage part of the contest, it gave out 27 MPG...
...my 04 BONE STOCK Sti gets around 18 these days. mostly city driving. 18 miles total per day of home to work driving.
driving on freeway like to los angeles, i'm lucky if i break 23... sigh...

I have been keeping close track of my mpg. I just bought the car and have only filled up 3 times. I am averaging around 20 mpg. For those of you who are getting good miles per gallon, what kind of city driving would you recommend? I have been shifting around 3k rpm to try and conserve a little. Since the car is new to me I am driving a little more spirited then I usually do, but would like to get some decent mpg also.

Other than that, don't WOT, keep driving conservatively, and get a tune so your car doesn't run as rich.
