This was the second oil change for my truck. It's been using 10w-30 synthetic blend as it was a new truck/motor.
Never use full synthetic in a new or rebuilt motor, as it's too slick and may - or may not - let the rings seat in.
However, my next oil change will be full synthetic now that the motor has a good amount of miles on it. I also use Motorcraft filters.
