<VV> Corvair oil

[BobHelt at aol.com]

Hi Jim,
 
All very true. But I would like to add that I believe Richard Widman in his 
 article and comments has indicated that the problem with GL-5 was not that 
it  would attack brass BUT that GL-5 was TOO SLIPPERY. Thus it would allow  
additional wear on the brass blocker rings (compared to GL-4).
 
Regards,
Bob Helt

As for  differential oil, they recommended their GL-5.  When ask about 
what  it would do to the brass syncro blocker rings in Corvair manual  
transmissions, they stated the sulfur compounds were tied-up in the  
molecules and would not attack  brass.
