So not knowing how the truck is modded and how it's driven I think it's strange people make recommendations at all. Obviously they aren't very concerned about the original poster, they are just conventional oil people out looking for threads to post in. It goes both ways and there are probably even more boutique synthetic fans out there.
Again, personally I wouldn't use a conventional in something with an oil cooled turbocharger. Historically my cars have done quite well on conventional, I'm not biased towards synthetic.
I never said anybody was anti-conventional, pro-synthetic or anything of that sort.
Since I lacked the statistics on the rate of turbocharger failures on light to heavy duty trucks, I referenced my experience with turbos and conventional oil. Like mentioned above a turbo gas and a turbodiesel operating conditions are two totally different animals and numerous types of diesel engines put hundreds of thousands of miles on conventional oil. Based on my amateur observation turbo failure is fairly low, though I do know the VGT turbos are prone to sticking but that has nothing to do with oil. So to imply that T6 will protect his turbo better than T5 doesn't make sense to me.
And by the by, in my recommendation to the OP I just said 10w-30...I never mentioned conventional, blend or synthetic. The only thing I said not to do was not to run the Mobil 1 0w-40 cause it is a CF oil and the Ford 6.0 requires a CI rated oil at min.
