5.8 Gas Mileage

[michaelsnodgrass18]

just out of curiosity what kind of mileage does anyone else get with the 5.8l v8?

[ASwaff400]

i get about 7-9 city and 10-13 highway and thats with a fairly heavy right foot...

I have the 5.4 Triton and after learning how to accelerate the truck, I get about 13 town and close to 16 hwy. When I first bought the truck I was only getting 10-11 in town.

when my truck was stock with 3.55 gears i was gettin 12 city and 15 or 16 highway... and thats with a really heavy right foot...

I'm getting about 14 city but that is a lot of lights and they are timed long. I can get around 20 on the hwy driving speed limit or just 5 over and light throttle work.

17 on my last tank.

How in the world are yall getting that kind of gas milage??? I do good to get 7 mpg..I have no engine lights on so all is running good I guess..any idea on how to get the milage out of mine like you guys are getting? I have a 96 f150 4x4 ex-cab with a 5.8 in it..no oversized tires"31's"...and I have modified nothing!

Try checking for codes anyway, there can be stored codes even without the cel being on. Is your truck obd1 or 2? If it is one you can check it with just a paper clip, if it is 2 you need a reader. http://fordfuelinjection.com/?p=13 Thats for odb1 Other than that, just replace old worn out parts. Simple things like brake drag or wheel bearings sticking can kill mileage. Or buy a 4.9, I get consistent 15 city 20 highway

thanx Russ....I got no idea if it is a 1 or a 2...everything is working good on the truck..no brake drag or anything...just bad gas milage...anyone know of any mods i can do to improve it?

What year is it? If it's anything older than 96 it's obd1 no doubt, obd2 compatible throughout certain years with an adapter of some sort. Obd1 is easier anyway. Better mileage.. lighter right foot and like I said, test and replace old parts. Make sure your airfilter is always clean and look at getting the intake from a 300 or 460.
