Need information regarding the use of GL-4 or GL-5 as gear oil and
damage to the syncro in the transaxile. Been told by Amsoil that if
the GL-5 oil has a API MT-1 spec there is no problem with using it.
Also been told by Redline only use GL-4.

Amsoil stated the difference between the two are the EP additives, GL-
5 have 50% more, these EP additive will corrode the gear syncros,
but GL-5 with a MT-1 spec have additives to prevent this damage.

Does any one know more about this subject?
