ok. so i want to get into oil analysis stuff. i'm using amsoil in my freshly rebuilt 6.2 which has like 1500 miles on it. i've seen the kits, but they don't really explain what you're doing or how to do it. can i get a thorough explanation of the benefits and process as well as recommendations about which kit to get? i know i could get one thru amsoil... but i'm open to other options. thanks all.
