MPG high and low scores?

[afeinman]

Challenged myself on the way to work this morning in the new GT and got 30.2mpg. (It's mostly highway, crowded, and moving at 54mph, so...6th gear and snooze...)

What's your mpg high and low score?

(I suppose we should probably mark whether the low score was on a track/drag strip--almost seems like cheating!)

Hehehe, finally one I can contest with!!! Weird to say I've paid more attention to MPGs than my 0-60 times/1/4 runs (mostly because I was more mind-blown with how efficient a V8 can be, AND get respectable times!! )

40 mph in 6 gear -- maxed out the gauge at 40 mpg, but fluctuates between 35 to 40 mpg. When constantly resetting the gauge, it claims 45 to 50 mpg.
55 mph -- 33 to 35 mpg
65 mph --29 to 31 mpg
70 mph -- 27 to 30 mpg, but commonly sits at 28 mpg
75 mph -- 23 to 25 mpg
85 mpg -- 20 mpg at best
120 mpg -- 10 to 12 mpg

EDIT: Currently in the process of re-calibrating the on-board MPG display. At this moment, it seems to be overestimating by 1 to 2 mpg's.
EDIT 2: 3.15 gears, 6R80 trans

Yeah, how do you do that?
I think my gauge is overestimating by a similar amount.

Had no problem hitting 31 on the lie o meter stock, Now boosted to the moon on E85, I get 6.8 around town, and 14 hwy at 70-75.

ROUSH phase 2: mix of Hwy and City 18.2

Haven't been paying attention to MPG while driving. But I drive mostly around town with brief runs on the freeway, and I'm averaging around 15.8 MPG. I don't speed (much), but I do like taking off quickly.

 

[tdstuart]

Don't think my mpg ever gets above 30 lmao. I get like 10-11 on average.

I have gotten 29 mpg on the highway at around 70 mph. I hit 30 mpg for a few miles once or twice. I think a convertible is not as aerodynamic as a coupe. Normally, I get around 19.8 mpg, as most of my driving is in suburban street traffic, with lots of stop signs and traffic signals. I can't complain. That's OK for a two ton convertible with 460hp.

I probably average 12-15 mpg with mixed driving (mostly city). Around 20 mpg on longer highway trips. I should mention I'm on E85 so that definitely deflated my numbers. On 93 I was averaging 18 mpg mixed and 22-24 on the same highway trips.

 

[wynand32]

Looks like I'm more lead-footed than some. My average seems a bit low.

 

[Shadow277]

Going 75mph on a flat high way, I can get 28 mpg. Generally on surface streets at 55 mph I can get 18 but my best is 20.

My worst is like 8 at the track lmao. Not the drag strip mind you, 80 minutes of pure, unadulterated fun.

Driving like a boring Karen on gasoline 95% of the time.......24.9mpg avg.
Driving like a boring Karen on E70+........ 16.9mpg

Driving for some pleasure and testing/datalogging/Dragy.......... Forget it.

 

[Roaming Stone]

Im currently getting 17 mpg on 93.
Mostly on the highway, cruising going 80. But it looks like I can be doing better.

 

[sirben711]

With a fresh oil change, inflated tires, and traveling at 60mph. I can average 38-42. The moment I hit the streets it drops to 23-26
