Thanks Guys....You need ti tell with engine you have 4.6 or 5.4
I get 20 mpg with my 4.6 on the highway at 75 mph in town is 15.8mpg.
I am thinking of getting a travel trailer ( 5000 to 6000 lb ) and thought I may need to go to a larger engine ( 5.4 ) But now I think for the money I can just add a supercharger if I need more power. That way I will keep my good gas mileage when I am not towing

I have a 1998 f150 supercab with the 4.6L windsor and 3.55 gears and average about 10to12mpg in town and 18 to 21 on the highway if I drive about 65 to 70. After 70 about 15to16mpg. the only changes I've made are a K&N air filter and a soft tonneau cover with 120000 miles on it I dont think thats to bad. My brother has a 2002 chevy with the 6liter moter and he gets maybe 9 to 10 mph on the highway. man that has to suck

have a 99` lariate ext cab, 2wd, 3.55 limited slip, 5.4 with 148,000 miles on it...full syn valvoline oil, with me in it and the sand almost 800# in the short bed with toolbox accross the cab side of the bed. On the highway going speeds consistently (cruise) over 75mph I get greater than 19 on the highway going up in elevation from about 400 to over 800ft, pulling, not pulling, 19. I used to have the regular 5w-30....the syn does make a noticable difference, particularly in the city, where my average went from 13 to a bit over 15mpg.

2003 SCREW Lariat 4X2 with the 4.6 - Have been watching this since purchase due to the fact I drive close to 80 mi. commute per day...Overall getting 17.5 or so, added K&N Intake and still watching and checking the data...looks like a little increase so far, hit 18 last tank. Driving in Houston, mostly all highway, lots of stop and go but flat.
