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?
