Just received the results of my first oil analysis on my 2005 Jeep Liberty CRD. It was done by Oil Analyzers INC with a kit obtained via Amsoil. 51775 miles on the vehicle, 2200 miles on the oil, roughly 800 miles since adding an entire can of Lubro Moly MOS2 moly oil additive. Engine is a VM Motori 2.8 L inline 4 turocharged diesel, 7 quart sump capacity with a Mobil 1 M1-301 filter. Oil is Traveller All Fleet Premium Diesel 15W40 conventional API CI-4 obtained from Tractor Supply Company (note - Traveller has since switched over to the CJ-4 rating). For the past 18 months, vehicle has seen what would qualify as severe duty - roughly 90% stop and go driving in town, short commute less than 10 miles each way. Mann & Hummel Provent Crankcase Vent filter, EGR disabled.
