Ditto. I don't do anything special for my changes. Eventually it gets mixed in and changed with the next oil change.

It is exactly how I thought, but was hoping to be wrong. I want to run a more racing oriented oil for summer ( track days and time attack events ) and a thinner oil for winter ( I also daily drive it ).

Thank you clearing it up.
