Which is why I mentioned the N20 for the oil specs, others may find this thread.

Oil change interval, depends on a lot of things which is why you should get an oil analysis done. as you can get a perfectly accurate for your car,your driving, and your living location recommendation for oil change intervals.

If a person drives very little you still need to change the oil. Water can get in the oil from humidity and condensation as well as combustion byproducts and fuel.

I have changed the oil on cars that sat a year and had a total of 4 miles put on them. But I lived where it is high humidity and had wide temperature swings. I have a friend that has a car in Airizona Desert that changes the oil every 5 years in his barely driven show car.

Personally with todays oils, a yearly oil change is a good idea if it's barely driven and in any place where humidity can cause condensation inside the motor.
