I have a 2007 Kia Sedona that needs to have the power steering fluid flushed . Hyundai / Kia spec. their PSF-III which they want over $22.00 a quart for ! Surely there is a good alternative to the PSF-III , however on-line searches are vague ...some say a regular power steering fluid meets the requirement and others say a ATF that meets Dexron III will meet the requirement. Any newer information - what are other late model Hyundai / Kia owners using as an alternative to the expensive PSF-III ?
