I'm obsessing about this and need to pull the trigger. Have about 23K on car and I'm going to do complete drain and fill, have new pan filter and waiting on Magnefine to arrive. The filter came with a rubber pan gasket so I need to decide whether to use it or not.
OM states to use "Hyundai Genuine ATF SP-III, Diamond ATF SP-III, SK ATF SP-III or other brands metting (sic) the SP-III specification approved by Hyundai Motor Co." I will most likely not use the Hyundai fluid, I would use Eneos Type SP fluid from NAPA for $4.79/qt in it's place if I go that way. VI is 175, kin vis @100°C = 7.388 and @40° is 36.23.
Amsoil has a deal going for free registration for a 6 month period for wholesale pricing so I can get Amsoil OE for $6.41/qt or Signature series for $8.71/qt. What are the main differences between these fluids? OE has VI of 180, 100°C = 7.5 and 40°C is 36.5. Signature Series has 165 VI, 100°C=7.5 and 40°C is 38.5. (I'm surprised by this 165 number)
Finally on my list is Castrol Import Multi-Vehicle for $5.74/qt at Walmart. VI of 200, 100°C = 8 and 40°C is 36.6.
I live in Pennsylvania and get cold winters. The car often sits and is used mostly for short trips. I'm sure any would be fine. (Thanks to Tribosessive for his information about the Eneos SP fluid.) What do you think?
