what kind of mileage to expect

[ferg57]

hello everybody first time to post thank you for the forum. have f-250 1996 7.3 turbo stock truck dont drive it hard 65mph easy around town will pull 24ft pontoon every now an then best mpg has been 8 to 10mpg .i bought truck used from old man who pulled camping trailer with it.has 117,000 on it and the only mod is no converter or muffler has a new turbo and waste gate unhooked.other people i have talked to say they get 20mpg from there 7.3 what could be wrong.truck has 4.10 gears.and could any one tell me what size my front an back fuel tanks are.

couple of things - there is no wastegate on the old trucks like yours and mine so you might want to figure out what is disconnected.

I get about 15ish city and 18-20 depending on a/c use and wind. Check your air filter too. I dont know much about gears but I have 3.55 gears and your's might cause lower mileage than mine but others know more than I on that.

Tanks are approx 17 front 19 back give or take a gallon. (that might be backwards. I think the front tank is slightly larger...)

Welcome to the site - you can learn a lot here.

I get 14-20...maybe his EBPV is unplugged/disconnected, not wastegate

My ebpv is wired either open or closed, but I have never looked into the benefit or detriment of it not working.The truck was modified before I got it. It gets around 12 to 14 mpg. I also thought it was a waste gate that was probably wired shut. Does anyone know what the benefit of it being wired is? Thanks A.R.

I normally manage about 15MPG (+-) with 4.10 gears highway driving.

You won't get near 20MPG from the truck with those gears

i'm with big k ,i average 15-17 mpg empty, 10- 12 towing a 26' 5er

I can get probably close to 16.5 HW, but average city/hw, I see 15....But depending on how "naughty" I am... it could be 12

Hope you have good luck w/ gittn that milage up!

best mpg has been 8 to 10mpg

waste gate unhooked.

8-10 is way low. You should get at least 14 but more like 16+.

As stated above there is no wastegate on your truck so it is probably the EBPV that is disconnected. If it is disconnected the EBPV may be closed or partially closed which would decrease the mileage greatly.

I have a 5 speed & 4:10's and running 40 miles back & forth to work, 65 mph hwy, plus a little city, I'll average 16.5-16.9 mpg. I just can't break that 17 nut. But pulling my 5th whl. drops me to 12.5. Even my 14' utility (quad) trailer will drop it to 15 mpg.

That's on dino fuel, I haven't checked since changing to bio.

Yeap, sounds about right
