As I understand it, all direct injected gas burners are subject some fuel bypass into the crankcase.

Ford is launching the EB program fleet wide except in the heavier trucks, I'm guessing that Ford isn't real concerned.

I'm certain about the Taurus models, but the F-150's can go up to 10K on a dump cycle or when the oil life monitor says to dump, which ever occurs first.

Currently I'm having the dealer dump mine on a 5000-6000 mile cycle.
