Autofrost GHG-X8 announced for Spring 00.  Now available from ATC Specialists, Inc as COOL TOPTMCOOL TOP is now out of production since modern R134a cars have better performance and the extra performance is no longer needed. Cooltop was intended for many of the poorly performing R134a cars of the '94-'98 period. Bobbie Burke has some remaining stock if you want to hoard some before it is gone.

Technical Discussions on Autofrost/R-406A; why they are better than R-134a and other blends. (Adobe Acrobat PDF file 236KB). Includes A/C operation explanations and diagrams. See why other alternative refrigerants often don't return oil to the compressor, causing it to fail. MINERAL OIL MISCIBILITY TESTS shows mineral oil miscibility test results with R12, R-406A/Autofrost, HOTSHOT, Freeze12, FRIGC FR-12, FX-56 (R-409A)

See what happens when you use a chlorinated refrigerant (Autofrost/R-406A, R-12, Freeze12, HOTSHOT, etc) in PAG oil designed for R-134a only systems. We say that chlorinated refrigerants should not be used with PAG oil, period. Other manufacturers state that [their chlorinated refrigerants] work just fine in PAG oil.
