Hi there MikeD not to be confused with MikeZ lol. Glad to have you around. I had seen you signed in a few times and wondered when you would post. Glad you got yourself a Titan as well. I am personally about to get my first oil change and I'm going with Mobil 1 0-40 it is pure synthetic and was recomended to me by Jettech a forum member here. Quite a few members are using this. Look in the Tech Tips section for some info on oils as well as the Mods section where there are oil sample test results you can look at.
