I sure hope it's still being sold--DOT3 is SPECIFICALLY called-for in every ABS system I've serviced (a couple), and in some other older cars. I bought some a year ago or so ago.

To make the numbering system on brake fluid even more confusing, DOT 5.1 is 
a non-silicone brake fluid, which is compatible with DOT 4 (and DOT 3, 
which I don't think is even sold any more.) 

Castrol GT-LMA is rated as DOT 5.1 and is an excellent choice for systems 
that have not been switched to silicone DOT 5 brake fluid. It has excellent 
moisture management and heat tolerance characteristics. 

But please, folks, let's not get started on preferences for silicone versus 
non-silicone fluids. If the car has never had its brake fluid changed, then 
it hasn't had the seals changed either, and should get replacement 
non-silicone (Dot 4 or Dot 5.1) fluid.
