PSF3 is what the manual calls for on power steering fluid for this Accent, though I can't find it! The dealer service department tells me they have never had PSF-3 or heard of it even after showing them my manual. They only stock PSF-4 and recommended it instead. From what I've seen PSF-4 and 3 are not compatible, 3 is clear while 4 is green. Some people say it's transmission fluid rebranded as power steering but SP-III is red. I know my mechanic got it when I had the engine swapped in December but I haven't been able to ask him yet where he got it, any idea where to get it?

Ok, I downloaded your owners manual, and it just says PSF-3.

My owners manual for a 1999 Elantra says PSF-3 or Dexron II.

I bought a bottle of Walmart Super Tech Power Steering Fluid last year. It has no designations or API specifications on the bottle. It's clear. I've been sucking out the reservior every few months and pouring in new fluid. I've had no ill effects for 20k miles. If it was wrong, I'd expect it to be noisy or leaking. It works fine.

It's up to you what you want to do, but if it was my car, I'd just buy the Walmart stuff and not worry about it.
