I have 3:15 gears and with the cruise set at 72, I wish I got the kind of mileage guys with 3:73 gears get.

Its not exactly as it seems..manual 3.73s allow us to tweak the numbers. Road grades like downhill..coast with clutch or neutral..Stopped traffic or lights ahead way ahead..same coasting..Lugging around in city in 6th gear at as little as 40mph. The mpgs on the display love it. I mean check out this pic of my trip home from work .

I can get as low as 7mpg on E85 with aggressive driving and as high as 18 on E85 with normal driving. 91oct numbers are far better!

Let me add that my previous post is just an example of an unrealistic intended drive home to see what is possible doing those things..My avg tank fills of petro have been giving me an avg of 23.5mpgs whichs is still pretty awesome.

I've owned my S550 for over a year and I think I've looked at my mileage maybe once. I do look at my accelerometer daily! :headbang:

16 GT/PP. Run 92 octane. 12.2 to 12.3 mpg average. Mostly driving around suburbia with speed limits 25mph to 55 mph. About 20 miles per day.

Ive been thinking my mpg is particularly low...

This is cheating:

I'd just filled up in California somewhere near El Centro and then encountered a long downhill grade. Seeing as how the car loves curvy roads, I didn't feel the need to brake or accelerate.

After 10-20 miles, my fuel economy was great! 32.1 mpg!

Ouch. What are your shift points, and is that with your "Track" setting on?
I thought mine was bad at 15-15.5 mpg suburban driving (also in PA)

Usually high 3's and I do usually run it in Sport+. I like hearing the Coyote :)

Lift your foot off that pedal on the right when you come to stop. I know it makes it sound awesome but that's making that MPG number go down LOL ;)

26.2 MPG on a recent highway run from Montreal to Toronto. Not light-footed.

That's on a V6 with manual trans, stock gears, exhaust upgraded to stock GT (bigger pipe diameter) and 6000 miles on the odometer.

lol - that explains a lot :D

3,000 rpm and up makes that mpg go down pretty quickly, especially with Sport/Track on. Addictive, though, once you get used to having that extra grunt....

My average over about 25.5k miles is 18mpg. My typical daily MPG's are 15-18. Lowest was around 13. Best over the course of a tank was 25-26mpg. I've had two tanks of gas where i've gotten over 400 miles. The 18 mpg is indicated and I trust it due to the fact that I actually got better gas mileage than my manual calculations due to the speedometer reading about 4% low. Adjusting for the speedo error, the computer calculation was accurate. However I now have new wheels and run 285/35/19's which are about .7 inches shorter and the speedo reads about accurately now, at least what speed the cruise control says. My speedo and cruise have never really matched :doh: The computer calculated mpg's are now about .5 mpgs under manual calculations. I will adjust the engineering mode accordingly in the fall when I return from a trip but so far very pleased with my PP's MPGs

I used to run in Track and sport mode all the time, but since the beginning of the year I've been keeping it in normal most of the time. I really don't like the unlinear nature of the throttle mapping in sport mode. The step ups are drastic and a minor throttle adjustment changes it too much. They should have just done a simple multiplier than the mapping they used. Then I would actually like it as it would be linear. Normal is much more predictable.

I have definitely noticed a difference in MPG's dependent on your driving mode. I hope the reasoning for this is obvious to everyone, I really don't think an explanation is needed for why you get worse gas mileage in sport mode lol
