A bit late but id like to share that these extended oil change intervals on the OHC gasoline engines are not in the engines best interest for a long life. Now at that same point of a long life, im sure the majority will be into a new truck before the engine is high mileage enough to show the wear from the manufacturers extended oil changes. If you want to follow your oil life monitor, change the oil at 3,000mi, or anything in between its a personal choice.
Once Ford went to the 5,000MI/6 month oil change interval with the OHC 4.0L, 4.6L, 5.4L, and 6.8L engines the internal conditions took a hit. I keep engines for life and stick to the severe duty maintenance schedule. I have many of engine still in my possession (mostly 6.8L 3V) that I have personally owned and maintained since new. I pull the engines from the trucks when the truck is retired from service. All the engines in my possession have over 350k original miles and are free from internal deposits/crud as well as have near factory compression in all cylinders. I re-gasket these engines while checking them internally and put them back together in case I need one for a truck im still using.
I on the other hand buy a few used trucks per year that have been totaled by insurance from accidents. I get the carfax/autocheck reports with these trucks and just about every one has a full service history documented. The engines in these trucks are 5.4L, 6.8L, and 6.2L with around 100-250k miles on them. The service record all show oil change intervals between 7,500MI and 12,000MI. When I pull the engines out and open them up the internals have a thick coat of varnish and light sludge, the piston walls have considerable scoring, the PCV systems are usually gunked up, and when I check compression I get readings that jump around between cylinders. Yes these engines run and perform but they are not the healthy engines they could have been if the oil was changed at a more reasonable interval.
Just wanted to share this.
My experience with longer/extended oil intervals have only been on 4bangers that I have owned and did NOT follow the manufacturer's intervals of 6,000 Km.
2L 300Hp+ lasted 500,000Km with NOTHING needing to be done to the engine, I sold it and the guy drove it for 4 years...
2.5L 400Hp+ so far 300,000 Km and nothing wrong as far as I know, I sold it a few years ago...
With both vehicles I changed the oil & filter, at the recommended 6,000 Km for the 1st oil change and then switched to a full synthetic oil which I didn't change for 18,000 Km but changed the oil filter every 6,000 Km. Both engines were run at 30% or so more Hp than the manufacturer's Hp #...
I don't care what oil you run or when you change it, you're probably going to have to change your alternator twice, your water pump three times, and your transmission valve body once before you ever need to address an internal engine issue. In fact, I'd wager that less than 1% of the current members on this board will own their truck when it finally requires internal engine service.
It's pretty clear that you went into this thread having already decided on what you wanted to do. That is evident by the fact that the results of the poll, and the feedback given, made no difference whatsoever in your decision. As strange as your plan might seem to most here, being your truck, what makes you feel comfortable is all that really matters.
I am curious though, what you feel the useful life of a non synthetic oil is. Since Ford does not specifically call for a full synthetic, and the 10w30 (recommended) of the Mortorcraft variety is not a synthetic oil, I'll make the assumption that the initial fill likewise is not synthetic. You will also notice that the factory installed filter is different than the replacement variety. Is it better, is it worse, is it the same.....anyway, be prepared to add some oil after you change that filter. It holds a good amount and makes a decent mess.
Don't take any of this as me trying to convince you or change your mind, I honestly could care less what you ultimately do with your truck, and it's clear that you have your way. This is how I kind of look at it, in regards to the IOLM, it doesn't know what type of oil you are using, synthetic, non synthetic, different viscosities...unless you believe that all oils are created equal, the IOLM is not a perfect way of deciding oil change intervals. The manual gives some examples of what effects the oil life, and what kind of oil change intervals one might see based on that. Nowhere does it mention anything about oil type being a factor. I could be wrong(I probably am haha), but I'm not comfortable with the idea of a conventional oil going 10k miles/1 year, and I also don't buy into the idea that the manufacturer suggested intervals are based on longevity of the components.
The ONLY way you'll actually know if the oil is any good, is to take a sample and send it off to the lab...
But, to do a sample properly, you have to collect it mid-pour out of the pan.. in which case, you've drained roughly half the pan's capacity.. may as well do an oil and filter swap while your hands are dirty.
Then when you get the results back, you'll know if you wasted your money changing it early, or prevented a fiasco because you got dirty oil out. The onboard OLM is only a timer, it doesn't know if you started your engine at -30*c not plugged in, to drive it 5 miles before shutting it off for there day, or if you put a 20,000 lb trailer on it and tugged it through Death Valley in August.
Don't go by that. Go off your usage, and mileage. Yes newer oils are better than from 30 years ago. They have more additives, keep things cleaner inside your engine, and better lubricated. Part of the additives being better, is they hold more particles in suspension, and some of them are smaller than the microns in your filter.
I know I'll be doing my first oil change between 1500-2000 miles, and the second about 4000 later, then 7500 after.
Probably overkill, but it's my truck, and that's what I've had success with in the past with these 6.7's
Side note, I grew up in PG, still have lots of family and friends there, one in fact works at the dealership you must have gotten it from. Good luck with the new rig
The part of your post I bolded is just not accurate. It may be true for older type OLM but even the OLM in my 2007 Honda factored in engine operation for the recommended oil change interval. Some OLMs may be more intelligent than others but, in general, if you make a lot of short trips or put the engine under heavy load, the change interval will be shorter. All highway driving and the interval will be longer. It is not just a timer. The OLM takes out the subjectivity of the owner deciding if the vehicle operation is severe duty or normal and whether severe duty operation is 100%, 50% or 25% of total operation. I'm all for owners changing the oil at whatever interval level they want.
Engine Oil Life Message Center Display
The instrument cluster provides messages to inform the driver about the engine oil life status, engine oil life reset status and when an engine oil
change is required. The duration of the interval between engine oil changes is calculated in the PCM and varies due to driving conditions. The
PCM assumes a base mileage of 16,090 km (10,000 mi) or 1 year for normal driving. However, this number is adjusted down for conditions such
as high engine temperature, high engine rpm, use of flex fuel, engine hours (diesel engines), oil dilution (diesel), engine torque (diesel), oil
temperature (diesel) and possibly low engine oil level. The PCM calculates and provides the engine oil life percent message to the IPC. The IPC
further converts the remaining engine oil life using the driver's configured engine oil life start value and displays the engine oil life percentage,
indicating the remaining engine oil life. The engine oil change minder can be reset at any time by the driver.
The IPC receives the engine oil life message from the GWM over the HS-CAN3. The GWM receives the engine oil life message from the PCM
over the HS-CAN1.
The PCM receives the engine oil life data reset message from the GWM over the HS-CAN1. The GWM receives the engine oil life data reset
message from the IPC over the HS-CAN3.
I dont know why people ask these questions. Read the manual !! I decided to change my oil at 5k miles regardless and then a year later my truck told me to change oil due to age.
This is like taking a crap and asking what TP to use and how many times should I wipe....Only you can decided

Yes, you are 100% right, I asked the wrong questions... It should have been what would you do, not what you think I should do...
It's whatever the manufacturer says... In my case what the oil-life monitor says 16,000 Km max.
as for the synthetic oil, its what the oil manufacturer says... Some say up to 24,000Km...
I change mine once the OLM gets to 10% or less. Change the fuel filter every other oil change. I use Mobil Delvac Extreme or Delvac 1300. It's been interesting lately trying to find either at certain times and certain stores. That's a discussion in another thread up here.
I, too, was brought up with the 3000 mile OCI, regardless. No questions asked. Bought a 99 Sierra and it had the OLM on it. Not a percentage back in those days, just a message when it was time to change it. Well, for the first year or so, I still changed the oil every 3k miles. Then, I decided to try using the OLM and I'm glad that I did. My OCIs have ranged from 4500 miles up to nearly 7000, dependent of how it's been used. Over 22 years later, all is still well. Ever since then, I've used the OLM for all my vehicles with no issues.
I was planning to go 1.5 to 2k on the factory oil but when I was chatting with a service tech while waiting for them to find a bedmat at 1k somewhere in the back they said they could take care of it while I wait and that there was no line. I'll have it changed again at 5k and then every 5k after that. Having records of a change every 5k at the dealer, with receipts, will make me more confident if something does go wrong in the warranty/ext warranty period that it wasn't user caused.
At 200k miles your number of changes and cost (noninflated) with $70/change is
40 at 5k/mi each for $2800
26 at 7.5k/mi each for $1820
Wait, I didn't realize this truck enthusiasts forum was actually about social improvement...
Anyway, if you were older, you would realize that your opinion has been shared by generations of young folks, including those who are currently old folks.
If you were wiser, you might understand why the old folks think like they do. Unfortunately that comes only with experience, which is generally related to age.
Yes, hence the comment that the old guard holds back the young. Longer they live, longer the hold the herd back.
Understand? What does that word mean to you? My understanding of why you did something isn't license to do something. I understand why Elizabeth Holmes did what she did doesn't mean "I excuse".
