Talking Mileage...

If I drive like an old blue-hair, I net 18 MPG.

If I drive normally ("USE THAT GO PEDAL!"), I score 15-16 MPG. Sometimes lower.

FYI - I never expected good gas mileage with my stupid need to accelerate at maximum every chance I get. However, I'm still hoping that long freeway trips give up 24+ MPG (like my old 450hp sportscar did - 27 MPG when cruising at 75).

Well I filled her up today

with 13.719 gallons and I got 220.00 miles on a tank.

Fuel Tank Capacity 15.9 gallons

220.00/ 13.719 = 16.699 MPG

OH Mommy!

I'm breaking it in on curvy mountain roads, so the engine braking is swaying the results.

225 miles on 10.1 gallons of high altitude 91 AKI = >22 mpg

I got 24 on a highway only trip and I get 18 or so around town. I have only filled up once since the highway trip from the dealer so I don't have enough data yet.

With about 1100 miles on the clock, my last two tankfuls yielded 25mpg (all highway, but including a few bursts over 100mph) and 22 mpg (mostly highway).

I average about 20-21 mpg with mostly city driving. I have had a high of 24 and a low of 18. Still in the break in period though so I am really taking an easy. Oddly, I seem to get better mileage in the city than on the highway. The 18 mpg was a 70 mile highway trip I took to a race track (no I didn't race). Also, that first quarter tank really drops off fast then it seems to slow down a bit.

Default Mileage

I averaged 20.9mpg for three fills during breakin. Std. Dev.. = 0.39, giving plus/minus 3 sigma 19.8 - 22.1.

First fill with a mix of break-in and post break-in mileage gave me 23.5. This, being outside of Xi control limits on the high side could suggest that the economy improved after the seals had seated, and I started revving it above 4000.

Interesting!

(Before Six Sigma Black Belts give me lectures on using X-individual statistics for fuel economy data, I'm also tracking with an EWMA chart with L= 0.1. The last data point fell within control limits.)

LMAO I can't believe you are doing statistical analysis on MPG. But here is another point for your plot. I average between 19-22 MPG city driving. I use 6th alot and try to keep the RPM's below 2500. I try at least.

Well, of course I am. It saved me money through predictive maintenance on my old Buick. It will work here, too.
LMAO...? I'm not a modern messaging expert. Could you kindly define this acronym for me?

Perhaps you can tell me at the same time why I see "Bump" everywhere?

That would be Laughing My Ass Off, and bump is used when one wants a thread "bumped" back up to the top of the list and shown as updated, hence the bump, since you must say something in a thread to get it the updated status.

got from Watkins Glen home on one tank, 375+ miles, about 29+ MPG, cruising at 80 on the thruway with ac going..

normal every day city driving (and some coudl say I drive a little aggressively at times) I was getting 21-23 MPG's.

on the race track, got a whopping 7.3 MPG's

not bone stock, but did not htink the mods would INCREASE my mileage, but it has, in a good way!
