Ok here is the deal, I have a buddy with a 2005 outback H6 similar to mine, his has 130,000 but he has been a naughty boy... he has not ever changed the antifreeze. It is factory fill. there is some brown sludge apparent in the cap and looking down in the radiator, it still has green fluid but is obviously well spent.
I have never done flushes because I believe in maintenance and get my fluid changed enough its never been sludge like that If ive ever felt necessary to flush i run a distilled run through, but I fear this wont be enough so what flush do you all recommend. I was looking to the schaeffers but they say not to be used with OAT antifreeze which is precisely what is in his vehicle....so any adice would be greatly appreciated
