How far have y'all made it on one tank? I know there is a lot of combos out there but I would just like to know in general. I've made it around 220 miles with my 5.8 E4OD 4X4 once but curious to see if anyone has got better than that. I usually can get around 200 miles on one tank but that's only highway miles.

 

I get around 300km a tank mixture of town and hwy. That's with the needle down to the red. I don't run it until it quits.

 

To the next gas station… lol.

 

Depends on the tank. They are different sizes. I have stretched it out to 240-250 mostly highway miles. That is in the ‘89 F-150 302/ M5OD 4x4.

 

240 to 260 mixed 30 percent town 70 highway. I've gotten over 350 miles all highway drafting a semi before

 

There are different size tanks? That's my bad I thought they were all standard sizes in this F-Series. According to the internet mine are 19 gallon tanks.

Thanks for all the feedback everyone. Would this mean I could possibly get a farther range with my set-up? It does run rich and still can't find where it's coming from so wondering if that's why mine seems fairly lower then what you guys are running.

 

I take that back, I have dual tanks and now that I actually read more I'm running on the front 16 gallon tank. I use to use the rear tank but the pump is on it's way out. I could hear it whining while accelerating so i quit using it before it went out.

 

This is from a current thread for an ‘88 which is the same as my ‘89.


Front: 19 gallons
Rear: 18 gallons

 

Thank you sir!

 

I've decided to never let mine get below a quarter of a tank again, because I have reason to believe that the pumps are damaged by running dry. That's just me, but I thought I'd put that out there.
I've never accurately checked my mileage, but I think the original rating was 10 to 12, and I drive like an old man.

 

As someone said, range will be dependent on tank size. That said the literature from back in the day - The base entry level 300-I6 with a M5OD would "on average" get 18 MPG. Every major option change would be a (-1) from there.

Add the 5.0 -1
Add an Auto. -1
Add 4x4. -1
Add 5.8. -1

The cab and bed didn't seem to effect this, in my case I had a 5.0/M50D/4x4 and generally got a solid 16 week after week on my commute. FWIW most of these came with 235/75/15s but even with 31s my freeway commute didn't change this. I would guess if you're all city toss this out the window. lol

Go Heavier
Add F250. -1
Add 460. -1
Add F350. -1

I was a Ford Dealer tech when these guys where new and this was a pretty solid formula for the day...when they were new and as we all know they aint new anymore. Still even after all this time I get 15 and think if you're getting some horrendous mileage there's probably something wrong. Unless your foots just sending it 24/7 lol

 

I have the dual tank long bed F150. The original window sticker says 37.2 gallons. Yesterday I stopped to put gas in it. No idea about the front tank, since it already had some in it. The rear tank was pointing to the line on the E and it took 15 gallons to fill it.
Window sticker also says 18MPG highway. So if you believe ford and their sticker, this truck should go 669 miles between fillups.

I have seen the videos claiming you can get another 1-2MPG by upgrading the fuel injectors to the '97+ 4-hole ones. Supposed to be better at atomizing the fuel or something. I was planning on trying that, but first I want to run a few tanks through it to calculate my current MPGs.

Are there anymore bolt-ons that are supposed to get better mileage for our trucks? One of those tornado inserts that go in your intake? Or a dongle you plug into the cigarette lighter?
I could see maybe a chip or reflashing the computer could maybe eek out a little more.

Mine's a '96 5.0, automatic, with a 3.55 rear end. Pretty much bone stock.

 

I appreciate all the feedback back everyone. I never really run my tank under half unless I'm really busy or I think I can push it. Yes, I do have a bit of a lead foot but not to the extent I think that it would only give me 200 miles of range. Safe bet I have a sensor that isn't working as it should somewhere. Not only does my rig reak of that running rich smell but it's almost always like that. The truck also surges and takes awhile to balance out (five minutes or so). No codes (checked at least a dozen times this month) as usual and not really finding anything on other tests I've performed test says its a problem. I've neglected the problem for now (even though that's a pretty bad idea) because I just went through a wonderful 2 month ordeal with this thing having the transmission randomly disengage and other cutting out issues. Turns out my two culprits were a bad ICM and a bad MLPS. As far as sensors go for those symptoms does anyone recommend checking anything? I've replaced the TPS, ICM, Coil, ACTS, MAP, and have cleaned several grounds and checked wiring and no changes in that behavior. Does it cold mostly but it has done it hot but seems less likely to do so. This problem was still present even before those sensors and I have cleaned the throttle body. Once she's good and going for 10 minutes the thing runs great besides the intermittent rough shifting into 2nd and when it does it seems a tad late but it is drivable now so I've ignored it too. I've tried different ideas on the shifting but haven't got far. I think it's a safe bet it's another sensor or something of that sort. I know I know I shouldn't just ignore this but because I'm a busy guy I find it hard to snag an afternoon to have a field day with it so I'm waiting till winter when things slow down for me. Once again thanks everyone! This gives me an idea where about I need to be and I'll crunch the numbers on my average economy next time I have to fill.

 

I routinely run both tanks into the E “red” zone. I haven’t had any problems with the pumps in 10+ years.

Same here. Worked at the dealership for 3ish years in the mid 90’s. I get 14-15 in mixed driving. The Broncos get the same mileage.

no but they will decrease the thickness of your wallet.

 

As for mileage, these trucks 4.9 5.0 and 5.8 usually got about 14-16 mpg mix driving. But in the last several years most I see are getting 12-14. Ethanol fuel maybe?

Most of these trucks I've seen can or could go about 350 miles or so city/highway on both tanks and slightly more highway only.

A lot of them these days may not go anywhere near that far due to being tired or just not maintained etc.

On trucks with only the single rear tank range is terrible, and most will be lucky to go 200 miles.

The Bronco tank is bigger and it is often swapped into trucks. I think there is also a truck specific conversion 30 gallon tank.

Most of these trucks have dual tanks besides RCSB 4wd. Those all have a single rear tank do to short wheelbase and transfer case. My friend had one of these 20 years ago, and we were always looking for a gas station. A 16 gallon tank will get you much farther down the road in a fox body Mustang that it will in an F Series truck.

The dual tanks never really increased range compared to a single tank in a newer truck. But it did give a nice buffer for being able to still drive home when one pump takes a dump.
