When I purchased this truck, I went with the Eco Boost just because I've heard alot of good things about it, not because it's gonna save me a whack of money on gas. I wanted to stay with Ford and wanted plenty of towing power and the Eco seems like it'll do what I want.
Sounds like it may be somewhat more economical than my current 5.4 and if that's the case, that'll be good, but I'm certainly not expecting a huge savings.
I have a glass boat with a 150 HP Yammie and that also goes thru alot of gas but I also knew that when I purchased it a couple years ago.
If I was really concerned about the cost of gas, I'd be towing a 12' tinnie with a Honda Civic.
We'd all like to pay less for gas, but it ain't gonna happen so we just have to suck it up and if we want to play, we're gonna pay.
