rotella vs motorcraft & 60k Service

[RachHandinit]

I am about to do my 60k mile service and i have been using rotella t6 oil for the past 3 oil changes (done myself) and was wondering if I should get the dealership to use the motorcraft synthetic oil since im taking the truck into the dealership or should I keep using the Rotella t6?

Thanks. Also how much does the 60k service cost you usually?

I have seen a lot of threads that start with "Rotella vs...." I have been used Rotella in mine and had good luck so far. Most of the shops around here use it as the standard oil even though it may not be the cheapest. If it was me, I would stick with it.

I have been very impressed with the rotella and want to keep using it. I just didnt know if dealerships cared if you didnt use motorcraft.
