Need power steering fluid recommendation?

[Oldblueaccord]

2025 my power steering is feeling a little old.

Any recommendations? Any one think the Honda fluid is still ok for our old cars?

I think I been using the Advanced Auto parts brand Honda equivalent.

I'm not sure you could put something in it that would hurt it. Afik it takes the plain "power steering fluid" some bottles still say Honda or Asian, but I doubt it makes a lot of difference. Now as far as what you could put in and feel, no clue lol. You could probably buy a fancy ATF.

Edit: Did some research

The original 08208-99961 fluid was a plain old mineral oil fluid. Honda's new fluids are backwards compatible. Honda recommends against atf because it contains more friction modifiers. You can use anything without friction modifiers, lower viscosity pretty much means better performance. Other things you can look for are anti wear additives and additives to swell seals if it leaks.

I found this here. Thanks for the part number.

Hot tip! order it online or pay the local dealers 10.95$ a 12 oz. bottle.

Yeah... Find somewhere selling it wholesale price like majestic Honda or maybe eBay. Any dealer part honestly, don't support their bs

I forgot I filmed it actually. Went down with the flu for 3 days that night.
