Napa gear oil?
 

I just bought a few bottles of this oil to run in my gsr tranny, it's 80w 90 gear oil, here is a link to the product http://napaonline.com/MasterPa...otive has anyone used this product and do you think its safe to try? It says it's made for manual transmissions w/ or without lsd in passenger vehicles so It seems like a good idea, I just need some opinions or reviews.

If your tranny is working fine.. then use OEM fluid https://honda-tech.com/forums/images/smilies/emthup.gif
If grind a little probably use penzoil PN: 3501 syncromesh

Gear oil and motor oil are not rated on the same viscosity scale, so 80w-90 gear oil is not nearly as "thick" as an 80w-90 motor oil would be. However, I do agree that sticking with Honda MTF or GM/Pennzoil Synchromesh is the best idea.
