Like the title says, finished my first full tank through the truck. Lot's of city driving (drop kids at school, drive to the store, run errands, all less than a mile), idling while fixing things, checking tranny fluid with some highway smattered in, 13.5 MPG.

All in all I am fairly pleased. I get to check hwy MPG tomorrow on a 150 mile trip.

 

not to bad for intown and idling

 

mine gets about 15 with an 318, and some mods. i think that is pretty good

 

should do good on the hwy keep at a steady speed

 

I hope mine is that good but I don't think it will be.

I am at a little less then 1/4 a tank and I have gone 220 miles. I am going to fill it up tomorrow.

I can tell I have an exhaust leak though.

 

a tank of gas lasts me too long to really measure over a full tank. i get 3-4 wks of driving out of a tank, and its my only vehicle, and i driive daily

 

pretty good... keep her tuned up! I'm getting 17mpg hwy and about 14-15 city

 

do you have any other mods to your truck besides what is in your sig? that seems pretty good for a 360

 

I had a 97 360 auto reg cab SB and got around 18-20 HWY 15-16 around town...I now have a 94 standard 318 reg cab SB and get around 15 everywhere in and out of 4X4. My 2001 Nissan supercharged 2WD on ebay right now is only getting 15-20 used everywhere.
Might as well use the V8 4x4 that is getting the same MPG...

 

i've done a little bite of mods to mine and i'm getting empty 15 to 16 mpg loaded i'm getting around 17 to 18 mpg but that wear my gears and set up come in i recomend getting away from stock 3.54 and with no tire change go with 3.90
