Out of curiosity, since almost no one changes the transmission fluid with OEM fluid (according to the forums), and Subaru OEM Gear Oil is GL5 while the transmission recommends GL3/4, does that mean Subaru themselves do not make an OEM fluid suitable for our transmissions?

I really enjoy the oem shift feel but really can't make a decision if I want to buy their High Performance Gear Oil after reading too many forum posts that it will deteriorate my transmission because of the GL5 spec. Please enlighten me lol.

I wonder what was put in from the factory..
