Ford 6.7L Power Stroke Diesel :: 2012 - Changing Oil Regardless Of Low Mileage

just picked up a 2012 F-250 6.7 XLT. I won't be driving the truck too often, probably no more than 5000 miles a year, and was wondering how long can oil last time wise. I would wait for the change oil indicator to come on, but was wondering if it's takes a year or so or what. Was probably thinking changing it out once a year regardless of low mileage. I have the service plan from my dealer for 3 years which they threw in but it's for 7500 mile intervals so maybe I can work something out with them. Def love the truck and now I hate having to drive my other vehicle as dailys.

Ford F-150 (2009-2014) :: 2010 Lariat Losing Fuel Mileage Suddenly

I have a 2010 F150 Supercrew 5.4 Lariat that just turned 100,000 miles that is losing fuel mileage all of a sudden... Over the years I'd get 16-17 mpg city and 18/19 highway(best I ever got was 20 mpg on a trip from New Orleans to Houston with cruise set on 65 all the way and no stops) always checked- tank vs miles, not on dash, and with every tank... I've changed all the plugs recently, did the BG Induction Service and BG Transmission service, K&N filter cleaned and recharged, about to do the MAP sensor cleaning also... I've dropped to 15-15.5 miles for the last two tanks...

Truck runs fine but maybe it's just me seems slightly sluggish when driving and accelerate to speed up quickly. Idles fine etc... I've just ordered a scanner for the computer, not that I have any codes YET...but I'm just trying to figure this out to get back to my normal mileage... Again no codes but what about the 02 sensors, they've never been changed... any other tweaks you knowledgeable folks can think of? Also ran Seafoam through the last two tanks... I pull a trailer from time to time... but not for a while... can the transmission get stuck in a lower setting since I'm told they "adjust" and need a few hundred miles to adjust back to non hauling?

Ford F-150 (2009-2014) :: 2011 - Changing Oil / Drivetrain Failures?

I recently purchased my 2011 F150, which is the first new vehicle I've ever owned. I have always changed my own oil, and if possible I would like to continue doing this myself. My only concern is any potential warranty claims down the road.

If I change my own oil can Ford blame any drivetrain failures on me? What should I do to maintain records of my own maintenance to prove I've changed the oil regularly?

I am aware that I must use synthetic oil and a Motorcraft filter.

Ford F-150 (2009-2014) :: Changing Gear Oil In Rear And Front Differential?

I have a 2009 f150 platinum and have been told both sides of the story now... that the front differential is sealed and need not be changed, and also that it is unsealed and can be changed. While asking this question I might as well lump in the rear differential as well. Are they both sealed or unsealed and need to be changed???

2010 f150 supercrew fx4

While driving down the highway yesterday at about 65mph I went to change lanes. As I was changing lanes I gave it a little gas. About half way through the lane change truck jerked like I had just been rear ended. I immediately checked my mirrors to see if I changed lanes in front of some body. No one was around. Truck still ran the same. Everything I'be read seems like similar thing happen to others at slower speed.

Ford F-150 (2009-2014) :: 2012 - Radio Won't Turn On?

Having trouble with the radio in their truck? When I started my truck today my radio would not turn on, no AM/FM, CD player, Suris or Aux input. It does not matter what buttons you press. The sync will not work and none of the controls for sync.

The display said Ford Tough then the temperature was displayed, but the clock was flashing on and off. There was no pattern to the clock flashing on and off it could flash once or twice then nothing for minute or two then flashes once to 4 times then nothing. I tried a hard reset by disconnecting the battery for over 15 minutes but it made no difference.

Ford F-150 (2009-2014) :: 2012 - Accuracy Of Oil Dipstick?

I've done 3 oil changes since picking up my 2012 Lariat 5.0 a little over a year ago. And I've always questioned the accuracy of the oil dipstick - seemed to always read 'low'.

I just changed oil tonight (Motorcraft 5w-20 semi-synthetic), and I measured the oil that I drained out - just about right at 8 qts. I put in 7 qts and 24 oz (about 1.6 - 2 oz over the 7.7 qts that it calls for) and the oil barely reaches the low level on the dipstick.

I guess between what I drained out and my current oil level reading, my dipstick is not accurate.

Ford F-150 (2009-2014) :: 2012 - Air Conditioner Not Cold Enough?

I have noticed that on my 2012 5.0 Screw that the A/C isn't very cold. It is no where near as cold as my last truck, or any of a number of late model cars I have driven. If it's over 85 and I have it set to auto (70 degrees) it will never get there and just run full tilt the whole day. Even if you select Max A/C and blow it on you you will never have to turn the fan down from being cold as in other cars.
