There's just no cost benefit, since it's more than ordinary premium, because it's something like 94 octane instead of the usual 91, and only one brand has it.
The offerings from standard fuel supplies around here stop at 91 (R+M)/2. I remember visiting Washington state, and typical premium was 92. Basically the only way to get anything higher than that in California is via a mixture of street legal race gas. I also haven't seen any fuel here that is sold as free of oxygenates.
