I think you worry too much about oil in general. Every engine will consume oil. Every and every time. As far as CEL, Iím sure there are other things to worry about. Donít take this the wrong way but in the grand scheme of things, the pale blue dot, etc.
Itís a car itíll break, itíll need fixing and you may not get to it right away. Cruise control is probably a vacuum or vacuum pump or some such.
P.S. I do my oil changes 4x year for 45,000 km annual mileage (Volvo) and 2x for Forester that does 12000-15000 km per year.
