i dont have the exact #s cause i haven't filled it yet but heres what my gauges looked like after come back from tulsa. last time people didnt beleive me.

and its not eactly the same cause now im supercharged and i ran the A/C the whole way and more or less kept the speed limit, as opposed to N/A and random A/C use last year and 95mph average.

 

i get 40mpg constantly by doing 45 on the highway for 3 hours at a time

 

I dint mean to threadjack here... but all the mpg and gas concerns kinda struck me yesterday... I saw a news report on a guy in north carolina who converted his 1981 volvo diesel to run on vegetable oil (diesels can do that with only a minor tune). thing is, when the state found out, they fined him $1000 for "avoiding state fuel taxes" and then another $2500 for him to get a fueling licsense.

teh tax man wants you no matter which way you go lol...

 

Final Trip meter reading = 330 miles
Fillup until auto shut-off= 10.9 gal.
MPG= 30.275229357798

 

have you guys read this on adding acetone into your fuel?
http://www.lubedev.com/smartgas/additive.htm

im thinking about trying it if any one else does it. seems kinda wierd that they dont want us to know this info but iono.

 

Mythbusters tried the acetone. It doesn't work, it actually hurts your gas mileage. I love that show

 

I just got 29.9mpg on an un-modded '07 five speed. I'd say about %80-85 city driving, too. Hardly any A/C, and some aggressive driving.

 

what speed are you going on the highway? thats pretty good.

 

65-70mph. Sometimes I kick it up to 75-80mph when I'm bored.

But I'm rarely on the highway lately, mostly city. And I accelerate a little aggressively. By that I mean staying in second gear until 35, then third into 45, and fourth until 50-55.

 

Man you guys make me jealous. I get 22 average, granted, most of it is city but thats still a hell of a difference.

 

yea same here

 

im gettin less then 20

 

Have you done any mods? Are you using the A/C 24/7? Or are you just a mad-crazy driver? That's a really low average for this kind of vehicle...

 

Whoops, I just realized you drive an auto as well. I know the EPA ratings say otherwise, but I really don't pay attention to them. The auto may even make it worse.

That's kinda odd, though... anything less than 20 on this car. I can understand averaging 23s and 24s, maybe even 22s. But wow, that's really low.

 

the auto should get better gas mileage due to the longer gears, its expecially noticable during highway speeds. i have a supercharged automatic.

if your getting that low mileage either something is wrong or its the way you drive or how you have to drive in your area.

 

the only downside to my mpg is i have about 10 stop signs to get to my house which is very annoying.

 

there ya go then, start and stopping screws mpg to hell, thats why city mpg is always a good bit lower then highway.

 

i get 22-25mpg on mostly city driving.

 

This is faked.

 

^^^ Um, prove it. Better yet, prove to me that my 30MPG on the FWY is "fake"
Tart.
