You only do an immediate oil change (i.e. within 100 miles) if you add Seafoam to the crankcase. This is a way to clean the engine internals when you are planning an oil change.
When you run Seafoam through the Secondary air valve you don't need to change the oil, you will see the Seafoam and carbon deposits burn off in the white smoke.
