Geez, you gize, how much fiddling it it really worth to you???  Seems 
to me like it's worth dropping by a Sam's Club or Wal-Mart (etc.) and 
getting it there.  The few cents a quart you might save doesn't seem 
like it's worth the trouble.

Of course, this from a guy who runs Amsoil and has each case shipped 
in via UPS......but that's the only way I can get it.

'Scuse me if this is too obvious - but why not just run DOT 4 in it?  
Once it came out, I ditched my DOT 3 and started using 4.  As far as 
I know, you can use the later fluid in the earlier systems.

FWIW - I also use silicone fluid in my car....my 280 ZXT has a clutch 
slave cylinder which likes to get pitted from moisture - so I dumped 
the DOT 4 and put in silicone fluid.  It doesn't draw moisture and 
should preserve the cylinder. I figure the reason the clutch slave 
cyl. did this was that it doesn't get heated like the brake calipers 
do, so the water never got boiled.   The silicone fluid has a slightly 
LOWER boiling point than conventional DOT 4, so it's not for racing 
apps. - but for street use, it's neat stuff and non-hydroscopic!  
(But pricey...)
