I have more than ten vehicles that get 10k changes ready to roll in my driveway, and NONE have less than 250k and running fine (still using only a tad oil in 10k ~ 1 liter). Some engines with over 500k still fine and dandy with 10k changes.

My 160 HP bone stock Dodge Cummins gets 10k (synthetic) oil changes and tugs around 30,000# in mtns. THAT is pretty HEAVY for a 1T 4x4. It is plenty happy with over 300k miles, I expect she'll see 1 mil miles with no major work needed. (Of course she is ONLY a 6 cyl )

YMMV.
My '02 Powerstroke says 3,000 in it's manual. The last two I went to 5,000 with 2012-2013 oil and technology. I don't want to push it to 7,500.

Do what makes MOST sense to you, your truck, and your duty service. If I were using Dino oil, I would have no problem doing 5K changes and did that for MANY YRS (bout 20+) using synthetics. (and in some cases it IS better). I only recently went to 10k, only on light / occasional usage or strictly ROAD mileage. The Cummins gets 10k (or 1x/yr... late fall), cause it is a Gen 1 (older, less worried about it, they go FOREVER). It gets occasional use but HEAVY as mentioned (It tows my dozer, excavator, and 10,000# tracked bobcat w; (6) accessories around.)
My biggest concern is MOISTURE (wet climate). I like to get the engines warmed up often as possible, and watch closely for condensation. (most important in Diesel fuel tanks as I learned on the FARM... ALWAYS top off at night (when tank is warm and empty) rather than in AM (after tank condensates through the night.)
My VW TDI fleet is aged too, but will last me the rest of my life. I have torn down MANY diesels, and when I can see cyl honing marks that remain at 300k, I am pretty pleased with my grade of oil and changes. Same with a 360 Dodge gasser that I bought BEAT but had always used Amsoil. At 300k it burnt a valve. Took off heads and the cyl were BEAUTIFUL, and it had a VERY tough life (dragging a 32'HR RV for 200k for Original owner retired guy.).
EXCELLENT filter quality is VERY key to longer intervals. I still change out my filters every 5k and add a fresh qt of Synthetic. Fleetguard makes synthetic / long interval change media in filters. You don't want some garbage (cardboard) filter giving up on you.
Synthetic prices have driving my CHANGE intervals to 10k. I have over 40 vehicles to keep FRESH. and am RETIRED... I.e. No Income... My Bobcat takes about 30 Qts per change (uses oil as coolant!). I think the Cummins and Mack is only 12 qt. (@ $6.80 / qt).
Even on my old 2004 Nissan Frontier the recommended interval for oil changes is 7,500 miles. I change every 6,000 or so.
Every 3,000 miles is completely unnecessary and wasteful unless your car specifically states this interval - most cars I know don't.
It's a waste of money to change your oil that often. I doubt you'll get enough extra mileage out of the car to justify the extra costs, something else will probably break first, like the transmission. There are plenty of people that still use the old 3k benchmark to change there oil, and dealers or service shops are more than happy to do it for them.
Ford was using 10,000 mile or one year oil change intervals for 2.3/2.8/3.3 engines in Pinto's/Fairmonts/Mustangs starting in late 1978! I believe they were using some of the first semi-synthetic oils. The V8's called for 7500 mile or one year oil change intervals.

Ummm... Is this supposed to be in support of, or opposed to, that oil change interval?!?!
As far as I know having clean oil & filter is always better..
Besides 10k is lots, I would do more regular oil & filter changes to protect the car and improve performance.
Oh sure it's better, if it needs to be changed.
If having completely fresh oil and filter is always better, what's stopping you from changing every 1k miles? Every 500 miles?
