I made a small list of SFA:
Silicate free antifreezes (AF) 6/04
Peak Extended Life AF
Zerex ExtremeLife AF
Havoline Extended Life AF

Shell Dex-Cool
Maxol AF LLMXL
Something I didn't realize is found in the above reference. Silicates will turn into silica gel over a long period of time. It says antifreeze with silicates has a shelf life of 18 months. I've bought the stuff on sale and have some that's older than that! Guess it's off to the hazard waste recycler.
