gas milage or lack of

i found out my gas milage for my car last night 8 miles to the galon.what about you guys.

 

0 mpg

 

I get average of 26 in my mav but its injected
6-8 average in my F100 with a 429
when it had the small block i got 10-13

 

I got one of those tornados and now I get better gas milage than the next-door hippie's hybrid.

 

23-27 in my '71

stock '94 5.0
Edelbrock 500 cfm
Weiand dual plane 8011 intake

whats your engines specs?
what trans are you using?
whats your rear end gear ratio?
whats your rear tire size?
what type of driving are you doing? (street, highway, racing, etc)

 

My Comet gets 15 to 18;

stock E7 heads
stock manifolds/2" duals w/H-pipe
Duraspark w/MSD 6A
stock C4 w/stock converter

Carb is a bit much for it,a 570,535 or so would probably do better.Headers would help probably.Car got about 20 or so w/the bone stock 2bbl 302 in it,w/single exhaust.

 

my stock 87 f150 302 efi 4 spd gets 11 mpg being nice to it

 

You got a problem. Im pretty sure my 347 will get that good.

 

my oil spitting 390 4X4 gets 17 the grabber gets over 20. you got too much cam or rev the crud out of it on the freeway...hehe someones 429 is pretty ripped also....

 

I get usually around 23 in town and being real nice with it on the highway i have squeezed 27 out of it
302 (91 5.0 HO) about 80,000 miles
B303 cam
performer RPM intake
650 dp Holley
Duraspark Ignition
stock E7 heads
T-5 trans
3.89 rear gear
At 60 MPH it only revs 1800 rpm,and i try to keep it around 1200-1500 in town.
Oh and the car has gone 12.90 at 106 mph at the dragstrip.
Just carefull tuning young man.

 

With the original 3:00 gear my 351W was getting 17 mpg if kept between 60 and 70 mph. At 80 mph that would drop to 15.
You could hear it getting in to secondaries a bit ... I had to buy a bigger amp for the stereo (no A/C, windows open a couple inches, motor going WAAAAAAAA ...)

When I switched to 4.62 gears, gas mileage became 6 mpg city and 0 mpg highway. ( it didn't go out on the highway anymore ... ).
Fun at the dragstrip, but miserable most everywhere else.

Just installed 3:55s in it and can't wait to try them out... I plan on driving this car a bunch again.

 

Gettin about 8-12 on the street and 15-20 on the freeway depending how I drive her.

 

maverick mpg

last time i ran the numbers i was any where from 8-15. depends how loud i turn up the v8 raido w/2, 3'' spekers

 

i just checked mine last week i get 11. so i only take it out on weekends
