Power steering mix

[funkmiester]

Ok I don't have the words for this but I'll ask anyway. I asked my wife to top the engine oil up. I have a very slight sump leak despite fixing it a couple of times over the years. Anyway I get a call and a picture , "in here?" So she topped up the power steering fluid reservoir with engine oil. Then sent a picture. Yeah... No idea how much probably half a reservoir full. I'm being polite and not using any of the appropriate words, I mean we've only had the car for a ******** decade. She is half way down the motorway miles away. Anyone with any experience of mixing the fluids? It will have about 150 miles more on it by the time it gets home. Thoughts? Will a system flush do the job or has it pretty much destroyed all the pipes/seals already and I'm in for a new rack? Incidentally is a new rack an engine out job? Anyone any experience (like on a third world adventure) any of mixing them.
