GL-5 is generally bad for brass but the Redline specifically says theirs is good for brass. I don't know on the other questions since as you said Redline information seems to contradict.

Joel - Sadly Red Line lube names are CONFUSING. ONLY the "NS" GL-5 is "modified" to play well with brass synchros. They claim it won't affect brass and meets the GL-5 Extreme Pressure requirements without being too "slippery" to allow the synchros to work.

The other Red Line GL-5 lubricants ARE NOT approved for use in transmissions (or transaxles with "yellow" metal.

Good point. I should have specified I was talking about the one in the previous link.

The red line MT-90 that I have is rated GL-4. Can I assume it is OK because of the GL-4 rating??? I hope so! Can someone get clarification. Thanks!!!
