It’s a good idea to change your oil every 12 months even if you don’t reach the mileage for the maintenance interval. The heat cycles from the engine creates condensation in the engine and the water reacts with the petroleum in the oil and produces some not nice stuff. I haven’t been reaching my interval but my car will still beep at me 30 days before the last oil monitor reset.
