My 83 used to get 24-25 on the highway, but it had a pocket calculator for an EEC. (EEC III)

ever since the new fuel pump filter and injector screen cleaning... it gets abot 27-28 hiway and about 17-18 city.

i drive that thing about 20 miles a day because of school and work.

Back with the 2.73 gears, I was getting mid 20s, sometimes as high as 28mpg with a mix of highway and side roads. In my one all highway trip, I got 33mpg.

As of last week before tearing a head off, like 13 traffic, 16 City, 31 highway with HO bottom/Cobra top end, aod, 2.73's. Exhaust is quite rich at 1000rpm idle (fixing this).

Last two highway trips it has taken me .2 gallons of gas just to drive 2-3 miles to get on the freeway though...running like with the warped head.

I get around 20 to 24 MPG. All depends if I keep my foot out of it.

i've been seeing how aggressive i can drive my car (to the point of holding my breath is some corners.) also gunning it whenever i feel like it (if it's in the right place at the right time, no endangering anyone.) drove traffic, city, interstate, and backroads. 65-75mph most commonly. 21.4mpg. i think my car is harder on tires than it is on the gas tank.

tripminder says i average 19.6 mpg and 36.2 miles per hour (i do a mix of highway and rural/city driving)... it's pretty accurate to what i see..... that's when i run 89... i only average about 17.5 when i run 87 (i think my timing chain is stretching because i'm at base timing)

Getting 18-19 city now with the new headgasket. Haven't driven it enough to get very accurate readings though. The motor hauls ass now though.

I have only checked mine when I drive to St. Paul, MN.
During that 5 hour drive, i average 28 mpg and run around 65 the entire way. I have 3.73's, Manual tranny with .79 5th gear.

Of course it will be a seriously different number this coming year. The 351 with a Tremec behind it will not have to work very hard but it will be eating more fuel just due to the size if the camshaft.
