The 6 month recommendation is only there to account for drivers who are daily driving the car and doing short trips, which is much harder on the oil. If your mileage is low because you seldom drive the car, and not because you do short trips, the oil will be just fine for a year or longer. I'd personally go 3k miles/18 months with that kind of use.Go a whole year? I thought the norm was 6 months? I dont mind changing it. It makes me feel good. Lol.
