A specimen, HAHAHAHAHAHA!! They do look at you a little funny when you hand them the little black bottle and say " I need to have this shipped asap, it's important, and is a matter of life and death,......well, for my truck that is!!" maybe that is just me hmmmm.
UPDATE- I just got the results emailed to me and they said I could go up to 6k before changing if I wanted. That is using 15-40 motorcraft. Also, and I quote, "This may be one of the nicest wearing 7.3 we have seen in a while, all elements are at or below normal for wear." Thats good news to me, definatley worth the $18.00 to have that kind of piece of mind.

And all that on Dino 15w-40 Motorcraft oil. Excellent, good for you and your truck. I'm getting ready to send a sample of Rotella 5w-40 Synthetic in. We'll see if my $84/case oil can receive such high praises. Sounds like you and your truck are in for a bunch of miles.
Thanks, keep me posted with your results, I have been contemplating syn. for a while. I would like to know what they have to say. I am hoping to get 300,000+ out of mine so we will see. I think it is very possible with routine maintenance.
