break-in oil?

OIL!!!! im a bit on the confused side.... what oil would I use to break in my new 360 with flat cam? my buddy told me to use desal oil. some older dude said regular 10W30 oil with comp cam Engine Break-In Additive. and boy was this funny the guy at the auto parts store told me to use trans fluid (WTF!!!) can any one here tell me the best way to go!
