gas mileage



Now that the weather has started to cool down significantly here in the Midwest, I've been seeing ~15mpg with E85. It is almost time for pump gas again. :(
 


straight highway i can roll 28-31, but city and mostly what i get, 18-20. i love to drive spirited. if i slow it down a bit i can get 21-23 avg. only drive 7 miles to/from work a day.
 
****ty weather and now were on ( winter gas ) mpg's is now 15 its still worth it, car wont be out untill summer gas is back on
 


My GTP got me around 250 miles to a full tank. As for the GXP, I've had it for less than a week, and I'm on approaching fill up #2. I picked it up with a full tank. I drove the *bleep* out of the GTP and of course just like any other LS4 rookie, I've had a heavy foot since I picked it up Thursday afternoon.
 
'94 3.1L-- I usually get about 30 mpg highway. The max that I've measured was just over 32mpg on a long-distance trip.
 


My winter MPG are currently : 13mpg/city with a semi-light foot and 24mpg/highway at 75mp/h.
In the summer I think it was, 15mpg/city with a hard foot or 18mpg/city with a light foot, and around 26-28mpg on the highway at 75mp/h.

This is a N/A GT using 91 octane.
 
Summertime, on a 300 mile round trip I would average right at 30 mpg; some days I could get it to 32 mpg. My trips back and forth to work (38 miles round trip) I usually avg 27-28. Wintertime, currently 23 mpg, and that is with it idling in the driveway for 10 minutes of a morning. I average 325 miles to a tank, but I could stretch it further. I usually fill up with 89 octane when the fuel gauge is a mark below 1/4. Car is a GT with 133K miles. Originial plug wires and fuel filter.
