Shitty Mileage

[gtpvette]

I commute 110 miles round trip every day. Mostly highway but lots of traffic, stop and go. I do 30MPG.

~24.5MPG with E85 and ~30.5MPG with 93

Only way I could see getting under 20MPG is if you're running around in 3rd or 4th on the highway, or the equivalent on normal roads. 6th isn't just for the highway peeps...

90,088 miles, and the average over that time is 33MPG Calculated (34 by the onboard computer which has never been reset). I've done nothing special to get there, and have been surprised by the efficiency frankly.

The FR-S is my commuter. I drive aggressively, but don't do track days and am rarely stuck in traffic on my commute (average speed on my 40 mile commute is 40MPH (40 miles average time, 1 hour), but varies from 35MPH to 65MPH along the route).

Lowest I've ever gotten out of a full tank is 27.6MPG, and that included a lot of in-town driving with a two-hour traffic jam.

All documented in the original post in my Owner's Journal (although its a couple of tanks behind, need to catch it up).

I dont see over 55mph on the way to work and im 27.6mpg

I do race to speed limit almost every time. But shift at 4.5k

It's not rocket science, if you get good fuel economy you probably satisfy one or more of the following conditions:

1) live in a flat area
2) drive at a steady speed for longer distances, engine gets warmed up, use cruise control
3) short shift (but not too short, too short and you'll have worse fuel economy)

If you get 'low' fuel economy you probably:
1) live in a hilly/mountainous area
2) drive short distances, engine doesn't get warmed up, or a ton of stop and go, never use cruise control
3) drive the car the way it's meant to be driven ( )

For a long time my average was just under 20mpg, how did I accomplish this unimaginable feat? I commuted to the train station 2 miles away, 7 minute drive. My motor was barely warmed up by the time I parked again.

Edit: one last thing, if you're a 'nervous' driver that rides the brakes or is constantly moving the gas pedal slightly even at highway speeds, your mileage will suffer.
