Your mention of "annual" oil change brought up a concern I have. I replaced my 2010 Ram CTD with a 2018 Ram CTD. The oil change interval for the new synthetic oil was increased from 7500 to 15,000 miles. Unfortunately they also added a second fuel filter which is supposed to be replaced at the same interval. I have yet to have the first maintenance but am expecting a huge bill for the oil and filter changes.
The specs also call for an oil change every 6 months regardless of mileage. Ouch. I often do not use the truck for many months except to keep it charged up. Does oil rapidly deteriorate just sitting in a seldom used truck?
Learn to do it your self! I exceed the 6 mo sometimes but I do a Blackstone analysis every change, I run full 15k. Stick with FleetGuard, Mopar filters. I run AMZ/OIL 15-40 Signature series.
