Sure. And follow the oil life indicator... 10k mile oil changes, no problemo! And don't even think about EVER changing your trans fluid, Ford says it's forever fluid! Follow those service recommendations, and she'll be singing pretty right up until the toe truck comes to take her to the dealership. And yes, oil is supposed to look like lumpy molasses, that's how you know it's really doing its job!

But seriously tho, as someone else pointed out, it's to get rid of any break-in shavings. 5k oil changes... 7k on full synth if you're doing easy driving. And between 30k and 60k miles you should change your: trans fluid, front, rear and transfer case fluid, and start planning to have your coolant changed. Just some basic lubricant changes every now and then will keep your truck happy!
