Even though I went through about a quart of pentosin, it never really went
anywhere besides the outside of the reservior. It did hit the hot exhaust
and burn off it looks like. I never really checked the steering right after
starting so can't help you there. But it does make sense it would take a
little while for the fluid to get to the foamy stage.
