The New LBZ's are imprewssive, huh? Nice trucks.
As for your whining sound, I don't recall hearing that from any of the ones I have worked on. Was the A/C on or something? Does it chage pitch or volume if you turn the steering wheel? Does it go away when its at operating temp?
For oil, I am biased, being an Amsoil dealer. I love my synthetics. :cool
For Dino oil, Mobil 1 is Delvac. 15w-40. Good oil. Just make sure you use quality filters. No cheap Fram crap. This is one place to not skimp.
