Lightbulb California Gas

I threw this up on another forum and figured I would add it here. It basically describes the gas used in California and the different seasonal blends. It also kinda explains why we pay loads more for gas. Happy readin'!

Back in 1999 Gov. Davis signed this law that basically damned all fuel economy and perminantly jacked up fuel prices in California. It mandated that California run off of fuel that was California Reformulated Gasoline (CaRFG). It basically called for more detergents and the general phase out (over 3 phases) of MTBE.

The 3rd and final phase (CaRFG3) started on January 1, 2004. Thats when MTBE was completely gone and ethanol took its place (as much as 10% by volume). There were limitations (to many to list) placed on gasoline used during certain months. This was to limit pollution during the hotter and heavier driven months. Thus the "summer blend". The reason the summer blend isn't used year round is because of the cost of producing the gas. Also the added detergents in the summer blend greatly reduce fuel economy.

The times that gases in California are used vary by location. They are divided by Air Basin's. Here is how it breaks down (summer blend use dates):


South Coast Air Basin and Ventura County: April 1 through October 31
This area includes Ventura, Los Angeles, Orange, West of San Bernardino, and West of Riverside Counties

San Diego Air Basin: April 1 through October 31
All of San Diego County

Mojave Desert Air Basin: April 1 through October 31
East of Kern, North East of Los Angeles, San Bernardino, East of Riverside Counties

Salton Sea Air Basin: April 1 through October 31
Imperial, Central of Riverside Counties

Great Basin Valley Air Basin: May 1 through September 30
Alpine, Inyo, Mono Counties

San Fransisco Bay Area Air Basin: May 1 through October 30
Santa Clara, San Mateo, Alameda, San Francisco, Contra Costa, Marine, Napa, South of Sonoma, and West of Solano Counties

San Joaquin Air Basin: May 1 through October 30
West of Kern, Tulare, Kings, Fresno, Madera, Merced, Stanislaus, San Joaquin Counties

Sacramento Valley Air Basin: May 1 through October 30
Sacramento, East of Solano, Yolo, West of Placer, Sutter, Yuba, Colusa, Glenn, Butte, Tehama, and Shasta Counties

Mountain Counties Air Basin: May 1 through October 30
Amador, Calaveras, Greater of Eldorado, Mariposa, Nevada, Central Placer, Plumas, Sierra, and Tuolumne Counties

Lake Tahoe Air Basin: May 1 through October 30
Alpine, East of Placer, and East of El Dorado Counties

North Coast Air Basin: June 1 through September 30
Alpine, East of Placer, and East of El Dorado Counties

Lake County Air Basin: June 1 through September 30
Lake County

Northeast Plateau Air Basin: June 1 through September 30
Siskiyou, Modoc, Lassen Counties

North Central Coast Air Basin: June 1 through October 31
Monterey, San Benito, Santa Cruz Counties

South Central Coast Air Basin (except Ventura County): June 1 through October 31
San Luis Obispo, Santa Barbara Counties

Here is a good map of it too.



Phew...now that just explains California gas. Arizona and Nevada have far fewer laws about fuel and that makes it cheaper and more effiecent in cars.

Yeah, this is true. Well, and the fact that Shoshone is right in the middle of BFE!
