11 mpg to 15 mpg is it possible mostly on driving style and small mods?

Any updates on this? Wait for results.

It's funny I had been thinking about a post I need to do on here. My mileage has been crap, 10.5 - 11.5 when not 90% highway which got me 12.5 Loaded unloaded made zero difference. neutral at stops vs in gear made no difference. I've been compensating by driving the truck minimally. I swear I drive like grandma with a broken right foot but it's just horrible.

Anyways I got a clunk from the front end last weekend and noticed that when I first touched the brakes they seemed to be sticking so I went in to get the brakes looked at.

Long story short $3400 later I've got all new everything from the master cylinder down. The brakes where all partially sticking and one had just gotten worse that I noticed. I filled up 20 km before getting the work down. so far I've only put 220 km on it but just going by the gauge and the extra pickup the truck now has I'd say I should easily improve on my current average. I used to go 300-350 km on the front tank. The gauge says E at 250-260 normally. right now at 220 it's at half... So in a few more weeks when I fill up again I'll update the tracker on here and post an update in this thread.

I will note that I bought a scanguage and really really wish I had been able to use it. even thought the truck is a 97 it's not obd2. I still haven't seen a vacuum gauge while I'm out and about and haven't decided to order one in yet. my wallet is a lot lighter after the brakes...

Yeah it those gear in axle.

My F250 never gotten 11 or above. It exact one you have but it reg cab with flatbed.


Fun 96 E350 351W with 3.55 in axle got 16-17 on hwy but honest it little weak on hill couldn't use 2-3 gears it struggle Hill were 20-25% grade so it tough.

You could try is remove cat convetor I been heard reports improve 1-5 mpg by do that.


Anywhere I am replaced 95 F250 4wd with 91 F250 2wd so I could put 3.55 then able use truck for work.

When it get old and that truck doesn't drive long enough it become plugged.


We just remove one on 91 Bronco and mpg from 14 went to 16 on HWY at same speed I go.

The point is removing a cat is illegal, and socially irresponsible. It's like winning a litter pick-up contest by dumping your garbage in everyone else's territory. You could remove your muffler, too. And drive with no lights on at night. All great fuel saving mods....

Oh well how come I see tons 90's Chevy with TBI blow black smoke they should be banned.


cat convector on F350 is weight almost 30 pound it size of guard pole where people hit with car.



You could try unplug injector and see if it does improve mpg

I for one am an advocate of replacing a plugged up cat with a free-er flowing model, but it still needs to be "legal" and do what it's made to do - clean the air coming out of the engine (had the same problem myself). Does it really improve FE, I don't really know.

My commute has now changed to half rural, half city driving vice 90% highway and I've still managed to improve mileage by re-teaching my right foot how to make my auto trans work for me.

I should have my scanguage next week, so I'm looking forward to more "foot training" as I learn what exactly my engine is doing.

I definately agree with the vacuum guage option, it kind of gives your right foot a conscience when you're trying to beat the clock getting somewhere.
