With a 5 qt. oil capacity and adding a qt. every 2 weeks you are getting an oil mix that is 20% new oil every 2 weeks. Every 2 1/2 mo. you've added the equivalent of a new oil change. By the time you hit your current 6,000 mi. OCI, you've turned over your oil approximately twice since the last OCI. Given that, I don't see why you'd ever have to change the oil. At the end of even 5,000 mi. almost all the oil that was in the engine at the beginning of that 5,000 mi. is gone and has been constantly replaced with 20% new oil every two weeks. I don't see that you ever have oil so old and worn out in the engine that you need to ever replace the oil. I'd run decent dino oil and regularly change the oil filter and never change the oil.
