My new Ford Truck OLM is far advanced over the 2011 version of the same. On the Ford factory fill after 5 months only the OLM showed only 63% oil life left at only 971 miles..............

Ford IOLM is based on 10,000 miles or 12 months. You may have only driven 971 miles, but it's been almost 6 months/half a year. That's why the OLM is at 63% with only 971 miles.
 
Agreed
But the old monitor did not take into account time
It could go 42 months and say the oil was fine
 
I will post pictures and oil change history on my Ridgeline when I do the valve adjustment in another month or two. Teaser up front: it has thrived on Jiffy Lube oil changes (either PYB or FS 5W-20) at MM intervals (8-10k miles) from 0 miles to 98,000 miles (previous owner) and it's clean as a whistle inside. I look forward to doing that job in another month or so, and will be happy to share the pics.

I will keep it on PYB 5W-20 and, due to infrequent use now that I work from home, will probably do 5,000 mile OCIs (which will be about one/year).

Gone were the days where most conventional motor oil grades are made with solvent-scrubbed Grp1 base lubricant. Modern API SN/ILSAC GF5 conventional oil is a GrpII+ base lubricant that deemed far superior than what we had in the days of yore.

Lastly: the "full syn" legal symantic in US differs to that of Europe, and for that the term "full syn" is murky at best.

I'd suggest you to read on as much as possible on similar subject matters posted by some of our senior technical posters instead of casually jumping into conclusions...

Afterall: motor oil and engine development technologies have changed quite dramatically during the past 30+ yrs, and what was then a norm no longer holds true nowadays.

Q.

You must have nightmares about engine varnish.

A slight amount of discoloration of the metal in the engine is OK, it is actually unavoidable.

Conventional oils are good for 5K.
 
Personally, about 8,000 miles as that is what the Owner's Manual said for an interval.

That being said, with the UOA's PYB can give I'd say it could do 10,000 highway miles and be fine.

What about the guys running to 8k or 10k?
 
5k OCIs.
2010 Hyundai 2.4L with 93.5k on the clock.
PYB 5w-30 (5w-20 on the fill cap, 5w-30 okay by book)
Over 90% highway, probably close to 95%.
No topping off during the 5k interval. Barely gets below the full mark at 5k.
Book - something like 7.5k normal service, but at 5k its easy for me to remember when to change and I think its good enough service. And seems at about 5k, the engine gets a little more noise, goes back (less noise) after a change. Could be just me but seems the same thing every time.

When I hit 100k on the clock, will probably continue doing the same (PYB & EOM filter), but have thoughts on occasion to try something else, dunno yet.
 
My friend's 14 Focus OLM went out at almost exactly 6 months and 1500 miles. I changed it anyway.

As for the OP: 6-8 months, 6-8k miles if it doesn't have a OLM.
 
I change up the Caravan's oil when the OLM indicates. I usually run a 5w-20 from a fairly large stash of Motormaster Formula 1 synthetic. HOWEVER, if I see a good deal on PYB, I get it. Running that in it now. My wife has a daily ten mile commute & most of it's service is short-hop, city-cycle. The oil is pretty watery & smelling of fuel when the OLM says to dump it. The intervals are usually quite short - always less than 5k kilometres. If I have a synthetic in there, I'll let it 'fester' another five hundred or so as I arrange a good time to get it serviced. The oil pan got rusted up tis past summer & was replaced. Everything on the inside was as clean to the eye as a proverbial whistle. No UOA done on it but I really think that everything is going okay w/ it.

2011 F150 owner's manual clearly states that iOLM is based upon 10,000 mile/16,000 km OR up to one year interval. Look for yourself: page 432.

I do not care whether is "synthetic" or dino. If SOPUS says it meets or exceeds Ford spec WSS-M2C930-A on the jug of PYB (which it does say) then that is all that I and Ford need for a 10K oil change. My BMW specs 32,000km OCI, which I have been doing for the past 205,000 km on a twin turbo 335I using the properly spec'd oil. Motor runs great. Burns 1 litre in between the OCI and has done this since new. Good enough.

You mean guys like you ?

It was an F350 diesel in 2011 and many could go about forever because it didn't have a time limit but an hour limit.
The dealership even told you it was a waste to change. However I disagree with that- nearly 4 years is crazy
Truck had 5,000 miles on it and was 42 months old and the OLM said- oil is fine.
Also in 20011 on this truck it did not read percentages like the 2015 gasser does,
 
On my 2014 F150XL (3.7 base V6), I recently changed the oil and reset the OLM,
after only 2 days of driving (not city stop and go, mostly country roads) and only 320kms (200 miles) the Oil Life Monitor had already dropped to 97%.

If my extrapolation is correct, 320 divided in 3(%) x 100 = 10600, according to this driving pattern it should read 0% by 10600km.
Shorter trips / colder winter weather will probably shorten the suggested interval.
