I'd go once per year regardless of mileage personally. I wouldn't let any oil go over 8-10K either but I'm a little weird about keeping fresh fluids in my cars

Paging Subdriver!
I run Amsoil in my car currently and will change for more once the DIC reads 0%. I'm sure it can go longer but, I cannot adjust myself to run ANY oil that long. My car is a DD so I am just that particular.

I'm with you brother ! I run Mobil-1 but due to my health, often I don't put much over 2000 miles on the car in a whole year, and the DIC says it's at 86%. But the owner's manual says change it at 7000 miles or once a year. Since it only costs me $50.00 to have the oil changed I do it once a year. But I'm a little strange about clean oils.

Put another one in the "strange" column. DIC is your friend.

I run Amsoil in my Vette and in my TrailBlazer SS. I only put about 700-800 miles a year on my car and usually change the oil before I store it for the winter. That being said, I think I'm going to leave the old oil in it this year and change it next year before I store it. I don't think it's going to hurt anything.

Where do you get a Mobile 1 oil change for $50?

I can't imagine my oil getting that dirty in 700-800 miles.

You can't use your DIC to tell when to change the oil. The program is designed with the specs for Mobil one 5w-30. Nothing wrong with Amsoil though. Change your oil once a year.
