Another oil thread-
My 450 was under extended mait, for the 1st 100k. When the oil change message came on it went to the dealer for whatever scheduled maint was then due. Seemed to be between 5000 and 7500 intervals. Is the oil change interval message something that is pre set and just pops up every XXXX miles or is the computer actually monitoring some types of operating conditions to determine when it lights up? Is this an end user parameter that can be set somewhere?
Somewhere around the 4th or 5th oil change caught the typewritter tick - took it back to dealer and they printed out the service bulletin saying it was normal and nothing to worry about, it went away after 1k or so and didnt come back until 2 changes later again stayed for 1k or so and went away.
So now going forward and being over 100k what oil should I be using and should I be adding something like Molly when its done? Vehicle is going to be used for heavy towing, hot weather highway miles. Live in south Florida so cold / winter is not really an issue.
Thanks for the education, I have really enjoyed this forum and learning about my powerstroke
