its a truck. if your worried about gas mileage you shouldnt have got one in the first place.

Third f150 I've owned and I can tell you they go out every time and almost always after the warranty has passed
Despite that, I wouldn't buy a GM product at ANY price!

Didn't take as long as I thought it would for highly intelligent remarks as this to be posted.

Bad gas mileage means you shoulda bought Mini Cooper and its not any fault of the vehicle, it's YOU!!!!

Hope that helps clear things up for you!!:lol:

2010 F150 5.4L Poor mileage after Factory software update.
 
Been trying to figure out what happened to gas mileage since update had done in Oct. I'll explain how I got to this point. Around Sept. started having engine Light come on, stay on for a while go back off. Really intermittent. Also noticed every once in a while when i would drive for a while then put in park engine would Idle up to about 2.5 grand and back down to where it was ready to shut off then back up. Cycle like this until you shut it off. Took in to Authorized for dealer only place truck has been since purchased. Oct.4th. I should mention truck now has about 45000 miles. Was about 38000 in Oct. Was told needed software update on Computer. No problem, no cost. What could it harm? Right? Gas mileage before 15-18 after 13-15. This was in Oct. Since cold weather more like 12-13. (This is actual mileage not the lie-o-meter) Purchased in Feb 2011 had 250 miles on it. Have not changed driving routines still back and forth to work 26 mile round trip and around town. Since the have had a problem with cold starts. After 2 weeks in shop, was told had water and too much ethanol in gas. Couple of cans of Seafoam and a fillup , Cold start problem solved. Watch you gas. Still stuck with poor gas mileage. SORRY for such a long Thread just want you to know where I'm at in this. Anybody got anything?

A year ago I posted my thoughts on this topic.
This year same story.

I get 11/12/13 l/100km in the summer and since the cold weather (-10 to -40c) is here I have crap gas, 10+ minute idling times, 200lbs of snow and crap/sand in my bed, lots of 4x4 use and I've doubled my fuel consumption (20-25l/100km)

Which....I totally expect

mods in my sig for comparison
