ENEOS Gear Oil GL-5 75W90

Just wondering, can i use this for my transmission? I want to change the transmission fluid since my gears are not smooth.
I see it's the same as Motul 300 in regards to being 75W90.

Reason for wanting to use this is because I already use Sustina 0w20 oil from them and like the product.

Thanks

Well, according to my manual, the manufacture calls for a GL-3 oil in the MT......not, GL-5.

This is what Wiki tells me:

EP additives which contain phosphorus/sulfur compounds are corrosive to yellow metals such as the copper and/or brass used in bushings and synchronizers; the GL1 class of gear oils does not contain any EP additives and thus finds use in applications which contain parts made of yellow metals.

"GL-5 is not necessarily backward-compatible in synchro-mesh transmissions which are designed for a GL-4 oil: GL-5 has a lower coefficient of friction due to the higher concentration of EP additives over GL-4, and thus synchros can not engage as effectively. Also, transmissions which explicitly call for GL-4 oil may have been designed around this lower concentration of EP additives and thus may contain yellow metal parts which GL-5 will corrode".


Your call .....:)
