I ran the semi blend in my 7.3 over 150k miles then switch to full syn T-6. Went into a Valvoline instant change just before Christmas for one of the early oil changes and the manager offered me a book of oil change coupons for their Christmas special. 10 changes for $300. I bought two books and had him write on the cover my truck description and license plate number. 20 oil changes at $30 a piece which at the time were $99 each with the semi syn diesel oil. He got fired a couple of months later. I got discount oil changes for 150K miles.
Auto Zone and others have great discounts on T6 a couple of times a year. Amazon is also a good source. I believe firmly in the cleaning action of the full synthetic oils and its resistance to breakdown. I believe mostly that routine timely oil changes are key, especially as one who keeps most trucks into the 200K+ mile range. But of course by the time I get my 2017 I might not have enough lifespan left to run up that many miles LOL

I do mine at 1k. The factory fill is 10w30 dino. HD service calls for 5w40 so I go to Rotella T6 at 1k when I start towing my 20k RV. These days it's not likely that any SWARF is left in the motor but a 1k oil change can't hurt in that dept either. Of course oil questions divide the forums like Moses at the Red Sea so you'll likely get a lot of different answers...

Dealer is doing first change and I will wait until 3K, maybe. I have also always made changing the rear end lubricant at 10K miles. I will have to investigate the recommended ratings for the elock but Lucas makes some very fine 80/90 products. In spite of better polished gears than years ago the high rate of friction on the helical cut spiral gears still produce micro fine contaminates I feel need to be removed. Why did they choose to remove the oil drain plug from the differential housing? PITA

Thanks for the link, Epic. Although many of us choose the Synthetic (I started back in 1990 in my Ranger) for various reasons I also understand the financial impact on some, especially when shucking out $75-$100 just for the oil not withstanding filters.
I would rather see someone change oil more frequently with good Texas grade oils than overly extending changes with synthetics. Millions of vehicles do just fine with conventional oils. Being a purist regarding engine maintenance is an obsession, one I am glad to have but I don't believe it to be the only answer: just the best one.
