Condensation is the main contaminate to be recconed with when changing oil on timetable rather than millage. In Fla. I would think 6 months is a start point if what few miles it is driven are in 50+ mile increaments at hi-way speed mostly. Short trips at low speed might warrant 4 month intervals. I am basing that on the assumption that the ccv doesn't do much other than put oil in the innercooler. I realy can't see how ccv can work very well without vacuum. Depending on how these opinions are viewed by the majarioty,I may start another thread regarding a modifyed ccv that has been rolling around in my head sometimes while

The ccv works w/ pressure - the max spec is 0.3 psig. It doesn't take much, but that is why I insist on a 1 inch hose for the ccv re-route. I frequently maesure the crankcase pressure. I am at or below 0.1 psig, but frequently at a vacuum under hard accelerations .... due to the high air flow rate through the turbo inlet duct.

my owners manual states 7,500 mi. under normal conditions. i do run out to 7,500 mi with a uoa every change with no issues. time based oc's are for the most part a waste. my 6.0 is a work truck, hauling up to 4000# daily running 150mi. down the interstate, 300 mile round trips. the only real reason i could see a time based oc prevelant is if the truck is going to be garaged for several months change before
