New to diesels

Hello, Recent purchase of 2015 Ford 250 6.7 B20 Do not know much history as to previous one (1) owner. Has 67,000.mi. Have tried to read owners manual as to maint., but not sure on a few points


1- The regeneration "flashed" for 5secords am I to continue to drive ? and if so how long at what speed. I understand the engine is burning shoot but what do I do about it?
2-Will the information display tell me when the two fuel filters need to be changed?
3-Same question for the air filter
4- The maint. schedule calls for the front transfer and differential to be serviced at 60,000mi What is involved ? I do not plan on any 4 wheel use ever!


I will be pulling a 8,000.lb trailer for a total of 10,000-15,000 miles per year and limited use in town.



Any suggestions to help this novice will be greatly appreciated.
Thanks

Welcome.
Do not trust any display to tell you when to change filters/or fluid. Keep a simple maintenance log in glovebox and record date/millage of all maintenance, tire changes, etc. If you use the log and follow recommended maintenance you should do fine. If a warning or service light pops up pay attention but, don't rely on them. The transfer case is always running power through it 4 wheel drive or not, do the recommended service. Service of differential and transfer case usually only involves fluid changes. Lots of good info on this site and youtube video on how to do it. This is the internet so take all advice with a grain or shaker of salt as needed, except mine. My advice is always right and if it is wrong it has never stoped me from giving it.

Wal Mart is a good source for the Motorcraft oil filter. Also, the Shell Rotella T6 and Wal Mart brand of DEF are god prices.


This site sells most of the Motorcraft items at fair prices. The foam pre-filter doesn't need replaced every time. The manual says to use the air restriction gauge to identify when the air filter needs changed


The restriction gauge, located on the upper
housing of the air filter assembly, measures
the vacuum inside the air filter. The more
the air filter is restricted (dirty, clogged),
the higher the vacuum reading.


Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 miles (12,000 km). If you
operate your vehicle in extremely dusty
conditions, check and reset the gauge at
least every 500 miles (800 km), or two
weeks, whichever comes first. Change the
air filter when the restriction gauge reads
near the change filter line and the gauge
is yellow.
If you allow the restriction gauge
to reach maximum restriction you can
affect your engine performance and fuel
economy.



Note: Do not blow out the air filter element
with compressed air since the compressed
air could damage the filter paper.



Note: Do not rely on filter appearance
alone. A filter which appears to be dirty may
actually have several thousand miles
(kilometers) of life remaining.



After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.



Axle Maintenance

Change the axle fluid anytime an axle is
submerged in water.

Rear axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required or the assembly has been
submerged in water.
During long periods
of trailer towing with outside temperatures
above 70°F (21°C) and at wide-open
throttle for long periods above 45 mph (72
km/h), change non-synthetic rear axle fluid
every 3000 miles (4800 kilometers) or
three months, whichever comes first. This
interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting
Ford specification WSL-M2C192-A, part
number F1TZ-19580-B, or equivalent.
Add
friction modifier XL-3 (EST-M2C118-A) or
equivalent for complete refill of
Traction-Lok rear axles. See Capacities
and Specifications (page 300).

Are the M275 and 10.5” axles ‘Ford-design’ and filled with synthetic at the factory? Or do the few that meet the rather onerous requirement of wide open throttle trailer towing for long periods need to change to synthetic to avoid the 3000 mile service interval?

I believed the rear axles are filled with synthetic at the factory. The front axle may not be synthetic. Maybe Ford-Doctor will chime in and let us know for sure.

I keep it simple:


Oil & oil filter every 7,500 mi


Fuel & air filters every other oil change (15K) [note: this is way overkill on the air filter, but they're cheap]


If you're severe service then go 5K oil/ 10K fuel changes.

One more novice question, How do I know if my 2015 ford 250 diesel has a limited slip differential? I also read about other type of differential but forgot the name.

Thanks again for your inputs and advise.

You have single rear wheels being F250, you might have an electronic locker. There will be a switch on the center console near the radio if you have the electronic locker.

Also, on the VIN decal on your door, the Axle will have an "L" as part of the designation if you have a locker. Mine has a 3L for 3.73 limited slip since my truck has dual rear wheels.

Thank you again Larrgh, I did not locate any knob/switch near the radio or any L in the vin number. So I have neither. But do I need to drive in four wheel drive ? if so how often? and for how long and at what maximum speed?


Hope I can help some else some day

I can't answer you about the 4 wheel drive as I don't own one. If you have an owner's manual, check page 162 about how to engage the electronic locker.

Sometimes a lot of questions can be answered by reading the owner's manual and the diesel supplemental manual.

if you do not have them, you can download here

Try gently pulling out on your electronic shift transfer case knob( unless you have a manual shift. ) there will be a lit icon on the instrument panel if it engages
