Fuel Mileage

[z250kid]

I hate winter fuel i get 11.5 to 11mpg. Summer is usally 15 or so. What can i do to get better milage. I have intake its clean and turbo back straight pipe. Clean Filter and fpr screen clean oil and im usally not over 2000rpm. I dont know if a chip is worth it just for milage. I dont want to kill my rebuilt trans. Truck has 4.10 gears. As much as i love my truck i hate spending 60+ a week on diesel. I need to get a car for work but money is tight.

accelerate slowly, anticipate braking, air pressure correct. skinny tires = less rolling resistence, idle time is bad, etc. chip normally will gain you a couple mpgs 1-2, higher gears will help. 5 speeds do better than autos

Stock up on summer fuel and dont let the truck warm up, just get in it an drive like you do in the summer.

I WISH I ONLY spent 60 a week on fuel. I am over 125 a week on fuel and I get 20mpg and gas is 3.59 a gallon

Good thing it runs on diesel lol, and I got 16.5 all the way from Cali to ga on this winter fuel, 4.10 gears auto, and 305/55/r20 tires

Other than verifying that all sensors are good, you don't have boost leaks or exhaust leaks pre-turbo, and replacing wear items, there aint much.
Fuel additives such as stanadyne may give you an economy boost, but from my experience the cost of the additive negates the fuel savings, so that's a wash.

isnt it bad for the truck to not let it warm up?

Only if you start romping on it from the getgo.
Otherwise, start it, give it a couple secs to build oil pressure, take it easy on the skinny peddle until it comes up to WOT and it's good to go.

yeah that seems pretty low for that truck..i got a crewcab Longbed 4x4 232k miles F350 SRW 4.10s and i get 19-20mpg..but i do run the stock tire size and keep it under 2k RPMs

The lowest I've have ever had was 16.4 mpg and I have manifold donut leaking and water in fuel sensor leak

I let mine warm up for 10 to 20 min and drive it easy, I have the tires maxed out to pressure posted on the sidewall that are 285's with 4:10's and an auto, no mods except the exhaust is straight piped 3" from before the cat to the rear axle and I get around 14 to 15 mpg's.
