when My 93 was stock, It got about 16mpg's. I have a Hypertech chip, catback exhuast, and a filtercharger. I also have 8.6mm wires, bumped timing, a tps mod, msd 6a ignition, blaster coil, and a few other things. I am getting a constant 19 now, (winter). Last July, I did a test and got 22.1. I am sure this will improve during the warmer months. I didn't have my ignition when I got the 22.1mpg.
The best thing I can tell you guys is, ease up on the throttle, avoid stop/go driving, use your brakes calmly, and if you don't have a tonneau cover or a camper shell, try dropping your tailgate. Try to keep the rpm's below 2200. I can guarentee you'll have better results. Also, some people on another site, did some 4-season mpg reports and found that winter months mileage droped. I suggest doing another test during the late spring, with the above suggestions, youll get a result. I did on several vehicles, including mine and company vehicles.
I have 95 ford f150 4x4 5.0 auto tranny. when i first got it with 35,000 it got an easy 20. then the O2 sensor went out and you talk about drink gas. it was lucky to 12 mpg. I fixed it and it gets 20 again.
just my 2
I've got a '95 F150 4x4 with a 300/5-speed. I've been trying to get past the steady 13.5 mpg for some time and have given up. Added new K&N filter, tuneup, slick 50 fuel injector cleaner, and even took it into the shop. No luck.
I read some reviews of the 302/351 and the writers claimed that they both get the same crummy gas milage.
From what I hear, the best bet is an improved dual exhaust system, as the 302 has had poor flowing exhaust ports for 30 years.
I have a '96 F150 XLT Ext. cab 4x4 short box with the 5.8 liter and I'm getting around 14mpg from normal driving and around 17mpg on the highway. A lightweight aluminum cap is on the back to prevent the parachute effect from the tailgate and it's also a place for my dogs to ride.
This problem should probably go into a different catagory, but I was wondering if any of you have the same thing. When cold the truck makes a clunk that I can feel when first going forward. It's after the truck is underway, not immediately after putting it in gear. I usually notice it at around 5 - 10 mph. Anyone else have this same condition?
I have checked the U-joints and the tranny-to- engine bolts to see if they were tight and they seem to be. Any help would be greatly appreciated.
I had that problem before in my 79 bronco. At about 5-10 mph it would make a loud clunk and I would feel the truck drop a little. It turned out to be the slip joint in the driveshaft. Try putting some fresh grease in it. Also check your axle U-bolts. Your axle could be twisting a little.
Thanks for the input, but my F150 doesn't have a slip-joint on the driveshaft and I checked the axle u-bolts and they were tight. Any other suggestions? Thanks again..........
Every post 1985 ford truck I have ridden in seems to have one of these mysterious "clunks" from under the cab when you take off or flex the frame in any way. I think there are several technical bulletins on this subject. Might sweet talk the dealer into letting the secret out. But, from what I understand the only permanent fix is with a welder and not beefier frame rivets. My $.02 worth.

96 4x4 Off Road
My '73 1/2 ton 390/4spd got a solid 10 mpg loaded or empty, my '72 3/4 ton with '78 351M/auto gets about 12, my 94 1/2 ton 6/5 spd got 17 when new, my 94 3/4 ton 351W/5spd got around 15. I think 10-18 mpg is standard (full size) pickup mileage and for all the engineering improvements(?) it doesn't get any better. I guess if you want mileage buy a 4 cylinder Ranger/S-10/Toyota/Nissan?
I have a 1995 4X4 F-150 I get around 18-22 mpg when i take my tail gate off but make sure you don't leave the damn thing in the ded they like to fall out...........I also get better gas milage because i have very low gears and i never drive at speed limit mostly over
Punkster commented on high altitude as being a possible factor in bad gas mileage. I have found to the contrary. I live in central Texas where the elevation is around 1000 feet above sea level and whenever I go to Colorado I see a significant improvement in gas mileage despite a loss in power. After thinking about it I have come to the theory that the thinner air decreases air resistance of the vehical and also decreases the conpression of the engine which makes it easier to run, but causes that loss in power. I might be wrong about my theory, but I know numbers dont lie.
Cold weather does have an effect on decreasing gas mileage. I live up here in MN and I'm getting 8 mpg with my setup. Everything is tuned up and running correctly. In the summer, I was getting 9-10 mpg. One thing to check is to make sure your tires are at the right psi- usually around 35 psi on f-150's running 30-31" tires. For every 5 degrees in temperature drop, you lose 1 psi in your tires.

I find I get 12.7 mpg in the city with "spirited" driving and I get 17 mpg on a road where I can drive about 50mph flat, with out stops and starts. This is on a completely stock truck except for a k&n air filter.
I sure would like to know what these guys with 4X4 F-150s with 302's getting 20 miles per gallon are doing. My 96 F-150 4X4 E40D auto gets 15 mpg (best)on the highway in overdrive at 70 mph. City mileage is probably about 13. The truck is a reg cab short box with several modifications including: Gibson cat-back exhaust, K&N FIPK (mass-air equipped), JBA shorty headers, Jet computer chip, Jet 180 degree thermostat, Bosch Platinum 4 spark plugs, 31 x 10.5 BF Goodrich Radial All Terrain T/A's, Summit cab visor, Lund bug guard and 3.55 gears. I run midgrade (87-89 octane) fuel and synthetic motor oil and auto trans fluid. I live in Colorado, so most of my driving is at higher altitudes (4,500 to 6,500 ft above sea level), so maybe the altitude affects my mileage but 20 mpg seems to be quite a stretch with a similar combination.
dont know if you or anyone else is still reading this thread 😂 1995 f150 eddie bauer 4x4 with the 302 and manual transmission. Get about 18-19 combined mpg. Sometimes when i tow it drops to 11-12. The secret is throw out your tires. I have a k&n cold air intake and upgraded ford spark plugs everything else is stock. Run tires that are not thicker than 9.5 inches and get all season. Good year and several other brands have truck and suv tires designed for mpg. Best i have returned on a round trip of about 200 miles going through canyons etc was 22.2 mpg all highway. Good luck 👍🏼
