Okay, I've searched and could not find an answer to my question...maybe this is a stupid question to ask about a 3.2 Porsche motor, but here goes.

I am expecting to get my car on the 4th..if all goes well with the Super Ferry from the neighbor island Kauai.
When I do get it, one of the first things I'd like to do is change out the oil. The car has 95k miles on it BTW.
I would like to flush out as much of the dirty oil & sludge as possible, as from what I read it's difficult to do with the piping and cooler.

Here are the questions:
Has anyone ever tried using automatic transmission fluid to clean the internals before draining the oil? I know most engine flushes are similar to kerosene, but I've read/saw with other motors, ATF being used as a cleaner prior to an oil change.

Would ATF cause possible damage to the internal is run for 5 - 10 minutes?

Another question, is there a way to drain the oil in the cooler and lines? I mean an easy way that is, without having to remove the cooler.

Any advice with this is appreciated.
