OCHS in vista sells 100 octane, http://www.ochsoil.com/racefuel/sunocol(h).html

VP in Rancho SantaFe 95.5 and 100 octane
6089 La Flecha
Rancho Santa Fe, CA 92091

and theres always the one in Pacific Beach

You can also go to motorcycle or ATV shops and buy it in a 5-gallon can, if you're ever in a pinch. Also 110.
