It's a part of the algorithm of the intelligent oil life monitor. Even if you barely drive it, the car's computer wants you to change the oil after a year. Maybe the oil isn't really burnt or contaminated. The additive package has not been depleted. You still have condensation. A little water sludge, which probably would have burnt off if you were driving the car more.
I just ordered some oil on Amazon. A 6 gallon box. Only $60. What did it cost them to ship a 6 gallon box of oil, and the customer gets free shipping?
