I am a old school conservative and old school car guy. You are the liberal, trying to preach and save gas. If the ecoBoost adds $2,395 to the price of F150, who do you think pays that in the Expedition? Total waste of money. How many payments is that? The V6 cash rebates are moving the F150, that and cheap leasing. My local dealer had a 2015 Expedition, left over, until late 2016. They couldn't sell it, even with $6500 in discounts. Across town, the Chevy dealer, had 16 Tahoes. Salesman said, they are getting many new, former Ford customers.
I've got to ask you RJ.....How many engines have you actually built? I'm just taking about the simple things like planning a set of heads or installing a set of con-rods? In fact, how many engines have you ever pulled and split open?
From the totality of your comments, I'm going to go out on a limb and guess ZERO. So where or where does all that negativity come from if it's not personal experience?
It can only come from one place....you are one of those gullible people that re-preaches what he reads on the 'net. Not a very sound basis for an education is it?
Do you even know the weak points of the 5.4V8 which you act like it belongs on hallowed grounds? Do you realize the percentage of headgasket oil & H2O leaks or crank bearing failures for any 5.4's that are fitted with high performance parts? How about the cam phasers
I speak from something that you simply don't possess, PERSONAL EXPERIENCE and I've owned 3 Expys, 2-5.4's and my new 3.5 and I disagree.
While owning my '17 since this past November, I've tracked my gas mileage since brand new and at around the 12K mark(I have over 17K in total now) I watched my mileage take a jump of around 1MPG so for example each tank was initially running around 17.4mpg and I would reset one of the three computer options when refilling the tank....the tanks now are running 18.6mpg and my gas mileage since brand new has steadily risen to 17.7mpg and I expect it to jump up to 17.8 in the next few days as the rise in mileage overcomes the lower initial mileage but trust me, I do not worry about mileage because I do not pay for gas.
I learned long ago that if you are going to bash something as others have characterized your comments, know what you are talking about and have practical as well as personal experience....you seem to think that the "old tried & true V8" never broke but that's very sadly mistaken as well!
The advantages that the "tough old V8" held in the 50's & 60's is GONE today, replaced by huge advancements in metallurgy advanced engineering & computer operation that relays temperature, speed and operating conditions.
Case in point: When I road-raced motorcycles in the 70's, we used to fit pistons to a clearance of 0.1016mm......now, it's .04mm and since you don't know what that means.... THAT is a DRAMATIC difference...all effected by the quality of the metals used today!
