I know this is beat to death, and I already know what these things average. Out of curiosity, what MPG is everyone else getting? I've averaged between 10.7 and 11.3 consistently in my 95 with a 351W, MAF setup (CA vehicle), JBA shorty headers, hot air intake filter, E4OD 6" lift, 4.56 gears and 35s. My 85 got about 11-14 depending on conditions, it was carbureted with the I5 and NP435, on 33s with 3.50 gears. My 1993 CCLB 4x4 F350 with 460/E4OD, 3.50 gears and 33s also gets about 11MPG consistently. I think aerodynamics are a big factor, however my 92 4x4 F150 with a shell, 2" leveling kit, 300, 5-speed, 3.50 gears got 17mpg on every tank regardless of how hard I abused it or if I hypermiled...

Driving style: fastest 10% on the road without being unsafe. I stay in the fast lane, retain some momentum after coasting up to corners, and am regularly cruising at 75-80 and not accelerating slowly. Think of the opposite of a CRV/RAV4 driver, and thats me.

Has anyone else had a freak of nature like my F150 that got exceptional mpg? My 85 bronco got better MPG on 33s after going to an e-fan, but still not close to the 92. I've even had a 2wd shortbed 300/5-speed 91 F150 and it barely broke 14 mpg when babying it.

Honestly, and I'm not being a smartass here, but if you own a Bronco you shouldn't be concerned about mpg. Unless of course it's getting 5 or more under normal target. Everyone probably owns one for a few various reasons, but I would wager that fuel economy isn't one of them.

I get about 13 around town and 15 on the highway. I drive like the Rav4 owner, makes a big difference.

With the short driving I do (2.2 miles one way, but occasionally some longer trips) I sit around 11mpg with my 302 with M5R2 and 265s. Back when I was doing just longer trips, I would usually be 13-13.5mpg, but I also had an E4OD then.

12mpg avg. 85 with built carbed 300, np435, 4.56 gears and lockers, and 37s. If I keep it under 55, that jumps up significantly.

I got 14mpg coming down from the rockies (down to 1000') at 80 mph. Only 10mpg going up. People dont realize that KS is not flat. The western border is nearly 4000' above sea level and the eastern hills are around 900'. In fact, there are 22 states flatter! Hell there are mountains in MO and AR that dont reach 4000'.

I haven't bothered to measure the mpg on my truck or my Bronco as I know I'll be disappointed with both having previously driven cars that got 25+ in town and 35+ on the freeway. I do keep track on my wife's Honda though as it gets the most use.

I will say this though, my 78 Bronco has to be getting half of what my truck does. My truck has a 19 gallon tank and the Bronco has a 32 gallon and the Bronco goes through gas faster than my truck does as far as watching the needle move. I also drive the Bronco a lot harder than I do my truck, so there is that. lol

78 Bronco: 351M, Holley Sniper, NP435, 4.56 gears with lockers, 35" tires.

77 F100: 302, 2100 2bbl carb, C4, 2.75 gears with open rear, 29" tires.


As for your freak of nature question, I've only had freaks of nature in the other direction where the vehicle got like half what it was advertised as getting even if I babied it.

Yo twofortyz,

As klh95bronco stated, we too get about 13 around town and 15 on the highway.
NO CODES, TIRES at 32psi, no brake drag, no pedal-to-the metal acceleration... etc.

I've gotten 476 miles on a tank (30.2 gals) once (just recently) and 450-460ish many times. I do a lot of highway driving back and forth from Greensboro, NC to Woodstock, GA 360 miles each way at about 70-75mph (corrected to GPS) the speedo reads 2-3 mph faster and average in the 14's to the 16's mostly in the 15's though. I keep a log of all my fill-ups, I run 40-46psi in my tires and no peddle to the metal either but I am a Spirited driver but I do move to the right to let others faster than me pass. Oh and I have 298K miles on the old girl.

I know that it's not a Bronco, but when I moved from Everett, WA to Seguin, TX, I had most of my possessions stuffed in the back of a 95 F150 Supercab shortbed, likely 800-900 pounds, and a homebuilt 'canopy' over it (hence the nickname S#!tbox), and from Ogden, through Soldier pass, and down into Moab, The truck averaged 14 MPG. And that was on a 5.0L, 31" tires and 2WD.

My best tank ever was 17.4 mpg. Currently, with 33x12.50x15 BF Goodrich All Terrains, my 5.8 gets right around 15 mpg on the highway as long as I'm not hauling a$$. Anything over 70, the mpg drop like a rock. Aerodynamics can be a bitch! Around town, that number drops significantly. I do a lot of short drives in town, and I'm usually around 11-12 mpg. Meh, it's a Bronco. When I want good gas mileage, I drive my wife's Subaru. We got 36 mpg yesterday on a 250 mile drive.

I wouldn't have bought my third Bronco as a commuter if gas mileage was a concern. I just like chatting about vehicle stuff, sorry if these threads gets repetitive for the regular forum visitors. On a fun note, the Bronco got 11.7mpg on my last tank, driving slower speeds than usual on one lane highways.
