Soundguy,
Go with the budget plan that saves the most bucks. All these oils are top draw and none will give you any issues. Unless you're willing to go full synthetics, your extended drains intervals won't be noticeably longer.
IIRC, the reason Ford went with semi-syn for their gas trucks is because they likely had to spiff up the specs to make 5w-20 hold up. Just a guess mind you, reading between the lines on Ford's tech releases.
At 5K drain intervals, dino would be just fine. No way a company like Chevron and a name like Delo is going to be junk stuff. Ain't gonna happen. These formulas are not that big of mystery, imho.
OK, you can't "sell" the old guard on synthetics combined with longer drain intervals. If you can't sell that, you can't. It's a trade-off anyhow, monetarily. Costs much more, keep it in the engine longer, = trade off.
Then, begin your budget cutting proposals at the purchasing level, not per se, the product itself. Why the heck would a company waste money buying from any source that is way over-priced? Convenience is fine, long time customer loyalty is also fine, but over paying NAPA just for grins? Na da.
Then, get down to the product. X cost for dino, and Y cost for semi. I can assure you that if semi syn is more than a 15% bump in price, it rarely is worth the added costs to the budget. But if dino and semi are sitting there at the same price? Semi wins hands down!!

guess it couldn't hurt to do the upgrade for me and the guy in the back room for one change, save a fist full of bucks on the others, use some of that fist full to buy 4 UOA's and see where that semi syn falls .. ie.. 2 uoa on the motorcraft / delo, at next change, and then 2 more after switch to the semi-syn, then compair them heads up, and see if that extra 10$ per change is doing ANYTHING on a shork 4-5K interval on those 2 trucks. then go from there.. my gut feeling is on that short change, the semi-syn will be nothing more than an expense as the dino oil will likely still be within useful specs.. thus that 10$ per change is more or less waste.. unless cold startup with better oil film from t he syn portion equates to that much benefit.. which I doubt it does...
