What MPG Do You Get?

[jakk]

See my sig, that's with mostly a 25% E mix. Switched over to 93 a few weeks ago and got 30 mpg my last fill up. I do about 90% highway driving though.

17.7mpg mostly city, a touch of hwy, and an auto cross mixed in.

I think I may try one of these apps out. I track (very briefly) my MPG and seem to average about 21 with almost all city driving. Which isn't bad given that most estimates put the MS6 around 18 or so


Tapa-what?

I get 24-25 city and 30ish on the highway. Don't get on it much in city limits though, hence the high city mpg.

I use Carango myself, it tracks gas, oil, maintenance, and a bunch of other stuff I haven't even touched yet. Even the free version is pretty robust.

^ That's nice. Gonna go get that fucker now

Dunno how ya'll are doing it but stock on a 2013 Speed3 5k miles... 21City & 24Hwy

It's all in how you drive. My best mileage was 28.5 on a long road trip, but during a month of taking logs for a tune, I got an average for the month of 15.7.

[JMEngineer]

My primary O2 sensor isn't working so I went with a very conservative tune and was averaging just under 18 for a while. Now with a little tuning I'm up to 26MPG average running 100% open loop (because no O2 sensor).

I believe 32mpg average for mixed driving is possible with a lean tune but I wouldn't try to do that without a built motor

highway, 30mpg.
City, 25mpg

Yeah, once you get over ~50mph wind resistance starts to become the bigger factor over mechanical resistance. Throw in a hood scoop, rear wing, and wide tires, and we've got lots of drag.
Don't forget windows. I LOVE cruising windows down, which knocks off at least a few mpg at 75mph.

24.54 mpg since I owned the car (bought it new).
I've used aCar from the first tank of gas onward. I can get close to 30mpg on a mild road trip and get in the mid twenties zipping around town. Most of my driving is city.
Autocross really drains the tank and kills mileage for that tank.
Max mpg = 28.74
Min mpg = 19.43

21 city, 26-28 highway depending on speed.
Jbr intake, jbr tip, test pipe, stratified ots+ tune, CPE tmic, fp internals, egr delete, and cc. Not bad but I am not shy about hitting the go pedal like a pimp smacks a mouthy hoe.
