700 KM = 434.959835 miles

 

When I went to Wisonsin (1,200 mile round trip) I got 19 mpg with the cruise on 65mph the whole time. 96 351, E4OD and 3.55 gears. Went on a 210 mile round trip and got 17 mpg the other day. As long as it's all highway it does pretty good. If there's any city its 14.

 

You must have a pretty light foot to get 14 mpg in the city.

 

1995 super cab
302 with 129,000 miles
33/12.5/15 bfg mk2
straight piped
gettin 12.5 mpg

 

I never take it above 1800 RPM's. And when I say city it's not stop and go every 1/4 mile. I'm sure if I was in actual city it'd be lower.

 

12 mpg with 6'' lift and 35's

 

that explains a lot.

And this:
12 mpg with 6'' lift and 35's

is actually quite good.

 

94 351 stock 160k --- got about 17 on the highway. 14 in the city

 

i feel like i'm getting terrible gas mileage now, i get 12.5 no matter where i go. guess i should do an ignition upgrade
351, 32x11.5, E4OD, open exhaust, K&N super cone

 

Looks that way too.
Ign. upgrade & error code scans & a Seafoam treatment.
