Good God! What a great way to create an undesirable event for what could otherwise have been an uneventful trip (eg post #18). Now if you were going to be out on the road for over 10k mi. OK - I get that. But sticking to a regular oil change schedule on a long trip for the most part I find so 'diculous it's kinda ridiculous. Is it that essential, that critical and in the big scheme of things, a factor that can't wait till you get home or somewhere not on the road?
