Hello Oil Gurus! I am pretty new to this site and find myself pretty well addicted to it. My wife says that I am now officially a "no lifer". Anyhow, I have been reading many of the UOAs with great interest. Is there a list or file out there someplace to tell me what ranges each category should fall into and what significance each one has to my engine? I think I am getting a rough idea, but would like to have a "cheat sheet to reference as I peruse. Thanks!
