I guess I shouldn't bitch anymore. I just got the truck a week ago and I took it on a six hour trip this weekend and got somewhere between 16 to 17 mpg on the highway. It's about the same for the city. I thought I was doing bad but evidently not.

 

Well, I must say I have been getting around 17.3 with 90% highway driving. I do the posted 65 mph as well. On a trip this weekend I let my (lead Foot) girlfriend drive and she would cruise around 75-80 and stomp on it to pass,(she loves the feeling of Ford power between her legs) and we got a whopping 13.5 mpg. So it does go to show you doing the speed limit will save gas but isn't near as exciting....

Was getting 15-15.5 mpg combined city and highway consistently. Added Magnaflow si/do catback and now consistently get 16-16.5 under the same driving. Now, my truck is not fully worn in yet, so some of the increased mileage could be from it getting more worn in.

I am very happy with it all the same. Now, if I got poor performance and the same mileage, I would be ticked off. I think the amount of power I get out of the truck is equitable to the gas mileage and then some.

for '00 SC 4.6L 5spd I've been averaging 15-16 w/ 75% city driving. Last couple tanks w/ the cold weather I'm looking at the 14's. Glad to see I'm not alone! Long term average is around 15.5 mpg.

Best I've seen w/ all highway was 18.7 mpg and worse tank was 14.1 mpg. Have yet to see the 20 mpg highway listed on the sticker. (Sticker was 15 city 20 highway)
