spikerS - being that you have an ecoboost and I believe the same 1st gen engine... as per RickDaTuner, frequent oil changes are more important than anything in this truck.
I don't run more than 5k, and I used many different oils, ranging from the Mastercraft (ford) semi-synthetic to the pennzoil ultra platinum
being that I change the oil as frequently as I do, I really cannot tell a difference, but for my own sanity, I use the best synthetic I can in the winter months, as I may not always be able to plug in the truck for an extended period at work.
Synthetics are just that... oil or NGL based hydrocarbons re-assembled to ensure the most consistency of the oil.
They are in varying groupings ranging from 1-5, where 1-3 are mostly "refined" (essentially distilled) mineral based oil (3 being semi-synthetic), and 4-5 are real polyalphaolefins synthesized lubricants
I believe that with even mobile 1, and most main brand fully synthetics are not actually group 4 or greater.
The pennzoil ultra platinum, Castrol Syntec (german) as is Amsoil, royal purple and Motul are group >4 and can be synthesized through varying feedstock from crude or natrual gas
With that all said, the higher the grade, the more uniform the hydrocarbon, which under extreme conditions means an increase to oil sheer stability (measure of the resistance of an oil to change in viscosity, caused by the oil being subjected to mechanical stress or shear)
likes ball bearings, the more uniform, the smoother and longer they will continue to turn.
With that said... Grade >4 oils will not yield any tangible performance or durability gains if the application does not warrant it. In fact the proprietary additives of the oil may be more beneficial for road vehicles.... and in fact I've heard that Grade 3> oils with a larger mineral base is more stable and better for DI engines that happen to be subject to gas dilution and soot.
Most Grade >3 oils are more than sufficient for all year round drive ability and I think frequency of changes with good quality filters is the most important.
I believe that Yota, Honda and Ford (and many others I suspect) all have moved to a high grade (3) semi-synthetic that has alloted for the extended change frequencies.
If you read the bob is the oil guy forum, the motocraft filter and oil has tested positively... I believe was even used for all the 1st gen release of the ecoboost engine torture tests
If SAY, I tow 8k+ routinely in all conditions for work, or was aggressively tuned, always racing and pushing those turbos to 20k RPM and those injectors hard, I'd definitely switch to a Grade 4 oil... but for those who aren't... there is no point
oh and as to the Amsoil "amway" type franchise model they have... my friend is one.
He has a 2010 5.4 F150 and has used their additives for the transmission, diffs, coolant and religiously changes his oil @ 20k intervals
well... he has 130k km on it, and now has to get the cam phasers replaced.
