His cars did last forever to the dislike of mom. Except for the 65 Chevy impala were the power steering hose ruptured driving back on vacation and the car caught on fire. Still remember standing a far bit back and seeing it go up in flames on the interstate in Indiana. We were 90 miles from home, heck of a taxi ride to end the vacation. Did get all new clothes and shoes except for what I was wearing!

I'm reading through this...I know this is an old post.
But I've wondered. With the oil cooler...there's gonna be a LOT of oil left in the system with a change. So...how much worse can it be to leave the filter in every-other change?
Not that I would recommend it; but the argument that leaving a filter in leaves a quantity of old oil in, was the one I grew up with. Now there's that elaborate oil cooler; and unless I break connections and drain it separately, there's going to be all that old oil in there. And probably twice as much as the tiny filter.
Hey...enquiring minds want to know!
