Cheap gas in Los Angeles.
 

Have been filling our FEH Hybrid at the Madrona Car Wash in Torrance, CA for the price of 2.69 (.10 discount due to car wash book). This is Chevron gasoline, seems to be the cheapest we can find.

Have been using these gasoline search sites:
Local - Los Angeles Gas prices
National - Gas Buddy
National - Gas Price Watch

Hope this helps.:)
