Hyundai Lubricants

I have 2007 Sonita and the owners manual shows power steering fluid as PSF-4. My 2003 Sonitia used transmission fluid. Does anyone know what fluids I can use for the Power Steering and Transmission fluids in the 2007 Sonitia and a 2007 Tucson?

what??? Your 2003 Sonata used Transmission fluid in the Power Steering??


The answer to your last question is SP-III for the Automatic transmission fluid, available only at Hyundai dealers.

As for the Power Steering Fluid (PSF), again go to the dealer to buy it ...

SPIII for transmission fluid on all years. You shouldn't have put atf in your power steering in your 2003, that's not what it took. As for the 2007, yes PSF4 is required, otherwise your power steering pump will whine. PSF4 is available from your dealer, kinda pricey though, I think it's around $10-$12 for a 12 oz bottle.

I believe that he ATF+4 used in Chrysler products is the same fluid used in the Hyundai automatic transmission (available at Wal Mart under the MOPAR label for about $4.00 the quart).

NO NO NO NO NO!!!

the ATF+4 is NOT the same thing as the SP-III, if you want to blow your transmission go ahead, if you want to keep your transmission go with SP-III fuild ONLY!

This is not a joke I've seen Hyundai transmission die fast because of wrong fluids were pour into it (when I mean fast I mean less then 500 miles)

The true Hyundai ATF facts:

PS and AT fluids are ALL hydraulic. The old Chry/Mitsu/Hyun spec was MS7176/AFT+3, re-badged by Mitsu & Hyun as "Diamond" SP III", etc. It was a VERY high spec for heat, oxidation, and mostly foam resistance. Foam=trapped gas=compressability, the enemy of good hydraulics. The 1998 MS 9602/ATF+4 set an even higher standard, which was then followeded by a Chrysler licensed quality control contract to an independent company. Only Shell, Exxon/Mobil, and Valvoline ATF Synthetic met the REAL non-counterfeit specs in the U.S. for ATF+4 outside of rebadged OE labeled ATF/PS fluids (probably from one of those 3 companies). Afton Chemicals instead of Lubrizol became the main additive supplier for ATF+4 and its clones at that time. If you buy a Hyundai Power Steering-"IV" or "Hyundai ATF" bottle, you will find that you paid a BUNCH for the assurance that you got REAL ATF+4. Wal-Mart also sells the real deal, with Mopar or Valvoline/Exxon/Mobil/Shell bottles, for about 40% of the dealer cost. You pay, you decide.

Don't take my word, no matter how accurate it is!
Do your homework:

Check with Daimler/Chrysler, the API, the ILMA, Lubrizol, and Afton Chemicals. Lubrizol formerly, and some other companies like the current supplier of ATF+4 additives, Afton Chemical, supplied all of the additive packages.

I am purging the OE fill in my 2006 Santa Fe's Trans and Power Steering. I am using Valvoline Synthetic ATF+4, the only product that I have found that actually, provably beats a few of the already high standards of the OE Hyundai ATF+4 product bearing their own badge on the bottle AND IS API CERTIFIED. If any "know-it-all" wants to provide a PROVEN challenge to anything that I posted, more power to them. I believe independent testing by the API and other testing organizations is the ONLY way that you should form an opinion on lubricants.

-->A note on AMSOIL: Their synthetics, including their ATF, rate VERY high when objectively tested. I can't use their otherwise outstanding products in my Santa Fe as Amsoil did not pay for the API certification process. I will only hand the local Hyndai dealership service dept techs a product that I can PROVE meets the Hyundai specs for the 2006 model year, which means the API label MUST be on the bottle. That currently, evidently excludes Amsoil. Your vehicle, you decide.

Concerning the Amsoil ATF,


I have used it in my 2002 Elantra for 100,000 miles now. Problems reported: none. Did my transmission act differently with the Amsoil compared to the Hyundai ATF? Yes.....it smoothed out dramatically. Smoother shifts, longer service life, better product. Hope this helps.

Same experience here. The only I suggestion I'll make is when using a substitute in Kia/Hyundia/Mitshubishi trannys they should be flushed by pulling the cooler lines, not a power flush.

they should be flushed by pulling the cooler lines, not a power flush. What's the difference? if they had to take off a cowling to do the flush, does that mean they used the cooler lines?

A power flush is when a machine is used, which is not a good idea in high mileage situations due to the force pushing junk into small orfices.

There's an easy procedure to flushing by pulling the lines while a helper runs the engine and you add oil while it runs unit it clears.

Don't literally dozens in this manner.

I believe that he ATF+4 used in Chrysler products is the same fluid used in the Hyundai automatic transmission (available at Wal Mart under the MOPAR label for about $4.00 the quart).

That's also the feedback I get from dealer parts departments, not Hyundai but Daimler/Chrysler, some of whose trannys are made by Mitsubishi who also makes many of the Hyundai auto trannys.

The Hyundai parts department person told me my 2002 Elantra needed a fluid with the SP3 spec. The Diamler/Chysler parts guy said he was pretty sure the ATF+4 fluids they sold included the SP3 spec.

I decided to try it so I bought Valvoline full-synthetic at Schucks for $2 less per quart than Daimler/Chrysler or Hyundai was selling their stuff for. I just finished a 2x drain and flush and the tranny shifts and operates with absolute normality. If it was not the right stuff I think there would be some irregularity of operation as the friction coefficient is really the key in this matter.

A KIA parts man told me Pennzoil meets the PSF4 spec. The Hyundai-KIA PS fluid is green and I had my 09 KIA Rondio flushed at 36K mi cost me $75. well worth the money to keep it warrantied. I know, the PSF doesn't HAVE to be flushed until 60K miles but I am particular about maintenance. The PSF is probably hydraulic fluid but the difference is it controls seal swelling and protects pump parts from wear while providing the proper friction coefficent for proper system operation. NOTE: The use of fluids not specifically designed for use in power steering may deteroriate rubber parts in these systems. Way I figure it, replacing the PS pump and other parts with seals plus labor and my inconvenience would cost a heck of a lot more than maintenance performed by a KIA/Hyundai technician using the proper fluid. Took them half an hour and I was happy to pay the $75.00

I had them drain (not FLUSH) the auto tranny and refill using KIA ATF $80. I believe Valvoline or Mobil 1 would do just fine, but then, what if the tranny fails and has something other than the right KIA-Hyundai fluid in it? So do it yourself and save a few bucks but in so doing void the warranty and have to pay for a $1,500. to $2,000. tranny rebuild. :banghead: Then to, I get ready to sell it I have maintenance records showing I took real good care of it should get me a few more bucks for it. I know the synthetics are great but there are thousands of KIA's & Hyundias running with thousands of miles on them using the prescribed Hyundai/KIA fluids so that's good enough for me. High stress and high temps good cause to use synthetics but for every day normal driving like I do the factory fluids work fine. Same applies with engine oil, synthetics great IF you need it but for normal driving good ole dino oil works fine.

Added next day: Look at how dirty this fluid was at 40,500 miles so I did right having mine drained at 36K miles. I wonder why Hyundai-KIA says no change until 60K miles?? http://www.automotiveforums.com/vbulletin/showthread.php?t=969197
