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?
Certainly the oils of today are better/longer lasting, when compared to 10-20 years ago. I think the biggest reason for adding a 6 month time limit for changing, to the lengthy mileage change, is to allow for the short distance drives, that many do. Many short, stop and go drives, is similar to high mileage, when it comes to time to change.
I don't think you need to change oil every 6 months, on a late model vehicle, that is seldom driven, but is at least fully warmed up, when driven. In any case, I would not go much longer than a year.
