Unleaded race gas has MTBE, I believe, to deal with the tetra-ethyl lead that's been taken out (leaded gas). I could be wrong, but that's how I remember it.

At any rate, even if CA has attempted to phase out MTBE, use of race gas, en masse, would probably never occur and because of that, never be a concern as:

1) It seems only four places exist from the Pacific Ocean to Pasadena where racing fuel can be pumped straight into a tank. So logistically, these stations are difficult to get to for most people.

2) Joe Consumer would never think of using race fuel, but;

3) While the hot rodder sees the price of premium leveling out with race gas and might decide to fill up with a batch, the hot rodder constitutes a spec on the consumer pie chart of who uses what octane-level of gasoline.
