Also would like to add,

I used aftermarket fluid( Some Bp brand) in my power steering pump in the past when I was still a Honda Noob.

Few months later started leaking.

I'm still contemplating whether it was the fluid or a faulty second hand pump I purchased.

-Having said that I have rebuilt my power steering pump
-Flushed all previous fluid out
-And now use Honda Power steering fluid.

Power steering is all happy again
And love my car again.

Just my 2 cents
