OIL
if you are running the Amsoil bypass system you can change the oil when the lab says its no good.
I have a 2003 CC SB Lariat 2 wd with 310,000 miles I have not changed the oil in 2 years.
Just change the 2 filters every 20k and send in a sample.
I run Rotola T 5 W40 syn along with all fluids and grease are syn.
