I am also from California where I believe the richest fuel is 91 octane (which sucks) but it'll have to do I guess. I suppose I could buy some of the products that supposidly boost the fuel's octane rating (bottles from Autozone, Pep Boys, etc.) but I'm not sure if this would be recommended...
You can add xylene or toluene to raise octane,it's better & cheaper than those octane boost cans.
Here are the formulas:
