After speaking with many many people and a few local techs......they suggested getting a cheap tuner that adjusts tire size......to hopefully help the fuel mileage issue

These Duratracs are listed as being 34.1" tall, but once mounted on the truck I get 33"

I bought a used 42501 Max Energy for cheap and programmed it tonight.......once I know the tire size is dialed in, I will need around with some of the performance levels of the tuner and see what happens

Right now I am at 14.0 mpg and 50,700 miles

Look at this nasty stuff, after only a week of driving.........Imagine it would otherwise all be going into the motor

I installed the same kit on my ecoboost.

after 10k miles, there is about a drop in there.

I wonder why there is such a discrepancy

Colder weather seems to produce much more condensation and build up in the catch can

The warmer the weather, the less I get on the can.......i still empty it weekly

MPG is hand calc and pretty spot on also with the computer

After I adjusted the tire size and drove 25 miles this morning, my more are up......way up

Should have adjusted the tire size a long long time ago.....i hope the number stay this high

Showing 17+ so far

Is that MPG your listing hand calculated or just off the screen? When I had my 2013 the screen was consistently high by 1-1.5mpg with all things stock.
mine is both. Sp far i don't think my trip odometer (I reset trip A every fillup or after a multi fill-up trip) has ever been off more then .2 -.3 mpgs. I haven't reset trip B since I bought the truck.....and I reset the average reading every oil change. It gives a pretty good idea of what I'm getting. In the winter I only average about 15.5....in the summer its closer to 16.5

What tires come on a stock 2012 FX4?

My door jam say 275/65R18........but would they have been Wrangler SRA?

If so, looks like these tires were 32.1" tall?

Duratracs are spec'd to be 34.1" tall

Mine measure 33" mounted

How are you liking the catch can and pedal commander with some miles under your belt?
Pedal commander is great, possibly the best add on

The catch can is a necessity, especially during the colder weather months when condensation is the worst

The 3 ounce can does fill up fast, though

now another issue with this truck......

my windshield wipers won't turn off!

Looks like a common problem on these trucks, with a new multifunction switch for like $30

I'll let the dealer deal with it when I take it in for the constant suspension clunking and creaking issue.....appt the last week of May

Mine had that issue. That swap is easy... maybe 10 mins.

Took a long weekend road trip to Missouri.....managed 17.1 mpg highway

With the warmer temps, the catch can is nearly empty..........seems like the colder temps produce a ton a moisture in the CAC

Got back last night and drop the truck off at a local dealer to have the clunking and creaking noise looked at.......

It will be interesting to see what they find..........I have the Premium warranty till May of 2019, that has a $100 deductible

Third dealer was a hit...……….no issues with any of my mods and found (and fixed) a few things, all for $100

The truck will be done this evening or tomorrow morning, the latest

The multi-function switch was faulty and replaced, to cure the ghost wipers

They found a bad ball joint (I believe the lower on the driver side)

They are also performing a TSB for rear pinion/rear driveshaft issue

The dealership called back and said I need front and rear brake pads, ASAP

The truck has 51,000 miles on it?!

My one ton Dodge went 75,000 miles before the front rotors warped and there was still a decent amount of pad life left

Oh well, for $120 they are doing the rear brakes (new pads, rotors turned)

They wanted $450 for front rotors and pads...…..no thanks, I will do that myself this weekend

I got around 60k out of my front brakes before I realized the pads brakes where metal to metal. Rears are fine so far with 70k

meh.

my in laws subaru needed pads and rear rotors at 31K mile. Front pads needed replaced too.

I really think the new shit is way harder on the rear brakes for some reason.

I did the rears on my wagon and the service count was 4 for the rear and only 1 for the front. So 4 sets to 1.
I don't know if they're using the rears harder because we've got ABS to keep it from locking up or what, but it's a trend I've noticed on everything newer.

I get the truck back from the dealer, with a fault code? WTF

B10F1

I know for a fact it wasn't there when it was dropped off

I cleared it out, see what happens


Here is the info on the TSB 14-0090 that was performed:

Some 2011-2014 F-150 vehicles built on 1/1/2011 and through 4/1/2014 may exhibit an intermittent click or snap-type noise from the rear axle on initial light acceleration from a stop while in drive or reverse. The noise may also occur on light acceleration after changing direction from drive to reverse, or reverse to drive.
