Normal Gas Mileage?
#21
My new to me truck seems to do alright in town/country driving i get 16mpg but if i hit the highway with a couple dirt bikes on board at 75 which it kills me to drive that slow out here i get about 13.5... just doesn't seem right i have a 99 5.2 4x4 with 5pd i just dont get how my mileage is better in town than on highway... it has 31x10.5 15s on it and maybe the 3.55 gears... i do need to do a tune up tho and i am wondering if she's got a dead hole...

gears - i thought higher gears got you worse gas mileage. i have the 5.9 with the 3.92 rear and have been getting 14-15 on the highway. if i put a 4.10 on there, the mpg's would go down, no?
cargo - have you made this trip with just yourself and no passengers/cargo with the same amount of gas and compared?
oil - have you tried a good synthetic (amsoil)? motor oil actually causes friction and a synthetic reduces that. less friction = less work for the engine = less heat = more power and better gas mileage
just my two cents!

In my case (V6), I have 3.55's with taller tires (effective ratio in the 3.20's). I get 18-20 MPG highway, but only around 10-12 city. If I go to 4.10's, I'll get closer to 16MPG both ways.
The reason is torque multiplication and application. With a high-torque motor (V8), you have more root torque, so you need less gear torque multiplication to get the same amount of power to the ground. For a weak motor (V6, I4), there is less root torque, so we need more gear to get it to the ground effectively.
If you have too tall of a gear, you'll bog the motor down in the city, but momentum will take over on the highway, you might lose a little bit if you do alot of passing, but cruise should go up. Too low a gear, and you're just burning gas, applying more torque than neccesary.

well i pulled the plugs and they weren't in the best shape nor the cap and rotor so i replaced all those and i will test the mileage again i am also waiting to hear from a guy in town with an exhaust for this thing anyone have or heard a pacesetter exhaust on a 5.2? it has dual tips that exit where the single factory did...
