I use the Royal Purple in my 04 ford f-250 powerstroke, it's a great oil but also,is's a bit high in my opinion & I personally can't tell much difference in it & the Rotella that I was using, especially since I still change oil @ 3,000 miles. I know you can go longer but I just choose to change it @ this interval. I've heard great things about the valvoline full synthetic "EXTREME" 5-40 & the 15-40.You might want to look at their product also. I'm sure the R/P is a great product, I just can't seem to justify the cost of it in my truck simply because it takes 15 qts.I will be changing to the valvoline next time I change oil. What oil is being used by someone has as many opinions as the brands of oil available, lots! All I'm saying is use the brand that you are comfortable with.In my wife's 2011 mustang I use Castrol Syn-Tec 5-30 & there again it works great for me. Great question, because it gets good answers from different people across the board.
