I have exactly the same truck. Averaged 18 on highway at 60-70 over a 300 mile trip. Getting 14-15 in this rural setting. Only mod I have done, or will do, is changed the muffler to a Magnaflow. Love the sound and will have to wait until next trip to check mileage and see if there is any change. Jim
Thank you for all for the tips. My 97 2wd extened cab I think got worse than the 2000 I just got..Do you think this is possible? I also heard some 4wd get better gas mileage because they are geared alittle different than 2wd??
I get 14 in town and 17 on the highway unloaded. Boat towing I get 12. I have 2 mods for the motor, a cold air intake and catback exhaust single pipe rear exit. 2001 F150 Scab 4X4, 17 inch wheels, 3:55 gears, 5.4L motor, auto tranny.
Well that maybe true about the 4x4 thing most likely not cause 2wd theres not so much drag cause 4x4 they beef up the suspension plus the added weight of the 4wd system it could be true that the 2000 gets better but a tune up will maybe get you better mileage maybe the 97 was in need of that driving habits also affect mileage
