If I delete all the codes will it wipe away where I am with my oil life from a dealer maintenance perspective? I don't know....can you please comment.
Codes are separate from the condition based service. That will remain in place. Even with the BT tool you can't delete individual codes but individual modules. If there is an issues with the car the code will most likely come right back, so no big deal.
