Posting here because it’s the most broadly suitable. I need to change the PS fluid and filter in my car - it’s dirty. I don’t really know what‘s in it (will remember to go out and get some on a paper towel tomorrow to see what it looks like). I looked into it and apparently either Pentosin 7.1 or some similar mineral oil or Dex/Merc ATF are both acceptable. I’d just as soon fill it with ATF since I can get it down the street in 10 minutes, but if I’m changing fluids I need to make extra sure all the old stuff is drained. I was going to unbolt the steering box and drain it from there - seems a little easier than sucking it out of the reservoir and refilling ~4 times. If I drain it like that, will I get it all out?
