I drain atleast 1-2oz per week from the PCV seperator. That equates to a 1/2 qt or more every oil change!!! (4 mos)
Normally that would be going straight into the UIM.

Stupid Ford! :rolleyes:
That is my only oil loss. It's been doing it since new due to Ford's idiotic design! IMO this is where everyone looses their oil too! (Outside of obvious leaks of course)
