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.

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.

Flat highway at 55 I see b/w 32-34mpg on my scan gauge.

**Archer3** · 12-29-2011

'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.

Er... what do you drive?

**00GT** · 12-30-2011

I get about 17-18 city, 26 highway

**WolvesSoulZ** · 01-01-2012

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.
