Bought a new 2012 Nissan Rogue in March. It is the first vehicle I have owned in the past 20+ years where the manufacturer does not recommend a 5000 mile oil change interval. Nissan recommends a 3750 mile interval. Additionally, the dealer provides free oil changes for the first year of ownership and has been using Mobil1. Two questions.
-First, is there anything unique about the vehicle that would would motivate the manufacturer to recommend the 3750 mile interval as opposed to a 5000 mile interval?
-Second, was Mobil1 the factory fill?
I plan to put these questions to the dealer but would appreciate advice here before doing so.
