91 octane is typically the highest octane gas you can find in California. Only at select pumps which are pretty rare (Maybe in big cities and at the racetracks) 87, 89, and 91 are the only octanes available. Not only do we have the most expensive gas in the country but also the worst octane rating. But we do have some nice mountain roads.
If there were any higher octane gas available, believe me, I would be filling up the scoob with it and cranking up the boost
